soft tissue in dinosaur bones debunked

'Blood cells' found in dino fossils - BBC News Dinosaur Bones Fossil age is determined using two methods, relative dating and absolute dating. But I wanted to show the chemistry behind these ideas, and that it plausibly explains the soft tissues and cells were seeing in, for example, dinosaurs. This Wyoming fossil has upturned the evolutionists Geologic chart to not be so logical anymore. Evidence for the extraction of short segments of ancient DNA from dinosaur fossils has been reported on two occasions. Questions remain regarding how the predominant preservation pathways change under different environmental conditions, but Anderson believes that demystifying the general chemical theory behind the processes involved is an important first step. Since 2004, soft tissue has been discovered in fossils all over the world, Uniformitarian explanation Sea levels changed gradually over millions of years to produce the enormously thick sequences of sedimentary rocks that record the long history of geological time. You would have to invent a These two hypotheses, taken together, dont answer every question regarding soft tissue preservation in deep time. Dinosaur Soft Tissue Dinosaur Soft Tissue Issue is Here to Stay - Institute for Creation List of Dinosaur Soft Tissue Finds When Mary Schweitzer saw red blood cells in soft dinosaur tissue her supervisor said, Prove to me theyre not. Keep your eye on the issue: how could stretchable soft tissues, cells and proteins survive for tens of millions of years against all the forces that would degrade them in short order? And they need to be tested quickly, as soft tissue could degrade once exposed to modern air and humidity. In a new study published today (Nov. 26) in the journal Proceedings of the Royal Society B: Biological Sciences, Schweitzer thinks she has the answer: Iron. Schweitzer has also isolated organic compounds and antigenic structures in sauropod egg shells. Please copy/paste the following text to properly cite this HowStuffWorks.com article: The oldest fossils, microscopic in nature, were discovered in a 3.5 billion-year-old rock in Western Australia. Flexible fossil shows tyrannosaur's softer to explain how it could last tens of millions of years. Both of these reptiles were titanosaurs, or massive sauropods that lived around 66 million to 145 million years ago. Does it make the tissue completely indigestible to bacteria? Scientists have had two decades to think about soft tissue preservation in dinosaur bones. 15 January 2008. (1/2/2008) http://wrgis.wr.usgs.gov/docs/parks/gtime/radiom.html, USGS. But carbon-14 dating won't work on dinosaur bones. World's Largest Dinosaur Footprints Discovered in Australia, Lewin, Roger. "What we found was unusual, because it was still soft and still transparent and still flexible," Schweitzer told LiveScience. "How Do Scientists Determine the Age of Dinosaur Bones?" If the fragments were due to contamination, they should have mapped randomly onto all regions of the collagen fibers. At the ALS, researchers identified iron particles associated with soft tissues recovered from two Mesozoic dinosaurs. Such implications that are immediately apparent from examining the chemical framework are discussed. How many are there, and which one is Jesus in? I don't care what they say about me': Paleontologist Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. Schweitzer was the first researcher to identify and isolate soft tissues (such as collagen, a connective protein) from an ancient fossil bone (Appendix A). Read on to see what it takes to date a fossil and what volcanic ash has to do with it. In 2000, paleontologist Bob Harmon found a They may have thought that if the Triceratops is 68 million years old, as it is supposed to be under the geologic time scale, then it would be highly unlikely, if not impossible, for soft tissue remains to have been found there. What are the idle words referred to in Matthew 12:36? 2005: dissolving the minerals in a Cretaceous T. rex fossil sample revealed structures that looked like millimeter-long blood vessels that flexed and stretched like real tissue when tugged by tiny tweezers. Once the protein strand breaks, the fragments are held in close proximity by the contact points. Scientists have also made improvements to the standard radiometric measurements. The soft tissues found by Schweitzer and others are not mineral replacements of soft tissue; they are the original soft tissue. The last step may be the trickiest: Possibly the most controversial part of reconstructing a dinosaur's appearance is determining what, This is a question-begging argument, like saying Whats the problem with saying Corvettes evolved by chance, refuting intelligent design? Since 2004, soft tissue has been discovered in fossils all over the world, spanning the entire Deep Time continuum, as Dr Brian Thomas at ICR has shown. And Schweitzer has even recovered fragments of the more fragile and complex molecule, DNA. Her work has appeared in theSag Harbor Expressand has aired onWSHU Public Radio. Traces of dino blood, soft tissue found even in junk bones Schweitzer was able to retrieve proteins from this femur in 2007. Appendix A: A summary of Mary Schweitzers research (Service, 2017). It was filed under Christian, Creation, Spiritual and was tagged with Armitage, biblical time, blood cells, Blood vessels, dinosaur, discimination, geologic time, proteins, Schweitzer, soft tissue. In recent decades, soft, squishy tissues have been discovered inside fossilized dinosaur bones. (LogOut/ Each of them typically exists in igneous rock, or rock made from cooled magma. WebT-Rex in soft Tissue!Tyrannosaurs Rex, the most popular Dinosaur in the world touted to have lived over 70 million years ago has been found in soft tissue. All these explanations proposed to explain soft tissue in dinosaur bones are tentative and not robust because they involve historical science in which the results of experiments done over a short period of time (maybe a few years) are applied to a long period of time (thousands and millions of years). Thomas T, 2019, Does the Toast Model explain fossil protein persistence?, Institute for Creation Research. My two topics are The Cells Design and Dinosaur Blood and the Age of the Earth.. Did you know that in 2013 a scientist was fired by a University because of his research into soft tissue in dinosaur bones? Subjects: Scientific Evidence for a Young Earth? Tracy V. Wilson Some researchers say that the detailed, external bone surface texture on the face of, say, the T. rex is just like that of a crocodilian. New Scientist. You can watch the tissue stretch in the video. A chemical framework for the preservation of fossil vertebrate cells and soft tissues. At the end of the Cretaceous Period, dinosaurs went extinct. Change). According to new research, iron in the dinosaur's body preserved the tissue before it could decay. That gives him an escape valve. Schweitzer and her colleagues first raised this question in 2005, when they found the seemingly impossible: soft tissue preserved inside the leg of an adolescent T. rex unearthed in Montana. John Morris from the Institute of Creation Research writes: Indeed, it is hard to imagine how soft tissue could have lasted even 5,000 years or so since the Flood of Noahs day when creationists propose the dinosaur was buried. This means that soft tissue in dinosaur bones provides another reason (besides, living fossils, coastal geomorphology, fossilization of large animals and orally-transmitted Aboriginal stories) to be skeptical of the uniformitarian (geologic) time scale. In response to these claims, researchers mapped collagen fragments isolated from theT. They admit it exists, but can only make up stories Since 2004, soft tissue has been discovered in fossils all over the world, spanning the entire Deep Time continuum, as Dr Brian Thomas at ICR has shown. Does he deal adequately with all the objections, like temperature fluctuations, percolating water, radiation and all? "The free radicals cause proteins and cell membranes to tie in knots," Schweitzer said. One of the most provocative pieces of evidence young-earth creationists cite for a 6,000- to 10,000-year-old Earth is the discovery of soft-tissue remains in a dinosaur specimen that dates around 68 million years old. Sauropod skulls consist of delicate bones held together by soft tissue and may have been prime targets for predators, Poropat writes in the Conversation. The specimens Schweitzer works with, including skin, show evidence of excellent preservation. Scientists have excavated the first near-complete skull of a sauropod to ever be found in Australia. And so all of you skeptics eat crow; away with you! Fossils can't form in the igneous rock that usually does contain the isotopes. Based on similarities in the part of the skull surrounding the brain, the bones at the back end of the jaw joint and the curved and conical teeth, the new fossil supports the idea that these two dinosaurs were close relatives, per the statement. How does he know it could? The study by Anderson also delves into the processes of carbonization and sulfurization, in addition to the best conditions for preservation.

Think of the nucleus as a pyramid of building blocks. Rare 95-Million-Year-Old Dinosaur Skull Uncovered in Australia. Iron is also highly reactive with other molecules, so the body keeps it locked up tight, bound to molecules that prevent it from wreaking havoc on the tissues. The result is like a radioactive clock that ticks away as unstable isotopes decay into stable ones. According to the laws of chemistry and physics, within a few hundred thousand to a million years, all proteins in soft tissue structures should be hydrolyzed and completely degraded. Exercise: LAAs paper is open-access. dinosaur The controversial discovery of 68-million-year-old soft tissue from the bones of a Tyrannosaurus rex finally has a physical explanation. Also proteins like collagen, hemoglobin, osteocalcin, actin, and tubulin were found. 5. And tests seemed to confirm the presence of collagen. Amino acid sequencing of several samples have shown matches with the known collagens of chickens, frogs, newts and other animals. Despite very good reasons to believe that collagen could survive for tens of millions of years in the matrix of dinosaur bones, some in the scientific community have questioned the soft-tissue finds.2 They claim these materials resulted from bacterial contamination of the fossils with microbially derived structures, thus creating a false appearance of blood vessels and cells. Scientists have had two decades to think about soft tissue preservation in dinosaur bones. Such a thing could hardly happen today, for soft tissue decays rather quickly under any condition. To preserve the chemistry of potential soft tissue, the specimens must not be treated with preservatives or glue, as most fossil bones are, she said. Based on the analysis of these samples, scientists estimate that the Earth itself is about 4.5 billion years old. Draw the Dinosaur's Face. "How do geologists date rocks? Get the latest stories in your inbox every weekday. Resurrected Vinyl on Twitter: "@JesseDornfeld Well the The discovery of soft tissue in dinosaur bones was unexpected and scientists have struggled to find a robust explanation. L ast year at about this time, it was disclosed that scientists had made an amazing discovery of a Tyrannosaurus rex thigh bone that still retained well-preserved soft tissue (which included blood vessels and cells). Does he face the objections to the crosslinking hypothesis presented by Dr Kevin Anderson in the link above? There is a lot left to explore. Change), You are commenting using your Facebook account. Nicknamed Ann, the long-necked specimen is just the fourth of the species Diamantinasaurus matildae ever uncovered. Trace Fossils In cases such as with coalified fossil wood, for example, this conversion of biomolecules towards kerogen macromolecules can preserve original tissue morphology (Gupta et al., 2007a; Gupta, 2015; Mustoe, 2018). Structure of Dinosaur Collagen and the Age Iron chelators increased fossil tissue immunoreactivity to multiple antibodies dramatically, suggesting a role for iron in both preserving and masking proteins in fossil tissues. Artwork by Scott Hartman reveals the bone structure of T. rex. The controversial discovery of 68-million-year-old soft tissue from the bones of a Tyrannosaurus rex finally has a physical explanation. According to new research, iron in the dinosaur's body preserved the tissue before it could decay. As the award recipient Schweitzer was the keynote speaker and presented on her research. How do scientists know the bones are really 68 million years old? Original article on LiveScience. Armitage was fired because of the intellectual intolerance that other scientists felt toward creationists. Darwinians Struggle with Dinosaur Soft Tissue CEH Remember that Mary Schweitzer shocked 60 Minutes host Leslie Stahl and dinosaur paleontologist Jack Horner by showing the tissue was still stretchable. ), Fixatives like formaldehyde keep the tissues from degrading in part, they make them less digestible to bacteria, says Landon Anderson, doctoral candidate at NCState and lead author of a study in Earth Science Reviews. This is a world famous area for finding fossil dinosaur remains. How does he deal with it? Yet Landon Anderson (hence LAA, to distinguish from Kevin Anderson), puts cells and soft tissues in scare quotes so as to raise doubt in the readers mind. Fossils represent the biological evolution of species. Before the law suit on this dismissal went to court, CSUN settled, paying compensatory damages, lawyers fees, and money for lost wages. "Understanding Evolution for Teachers: Radiometric Dating." Cookie Policy The tissue must be something else, perhaps the product of a later bacterial invasion, critics argued. Did Dinosaurs Turn into Birds? | Answers in Genesis These are complex molecules that continually tend to break down to simpler ones. Give me time in the future and all your doubts will fall. You would have to invent a Armitage believes that if dinosaurs have soft tissue in their bones, then something is wrong with the belief system that says the world is billions of years old. The big question is, why are the soft tissues still there in dinosaur bones when artificial decay experiments show soft tissues can last thousands of years but not millions of years? To read the time on this radioactive clock, scientists use a device called a mass spectrometer to measure the number of parent and daughter atoms. Using a mass spectrometer, they carried out chemical analysis of the putative The earths geological and climatological history has determined the current geomorphological and geological structure of the earth. rex femur onto molecular models of human and rat collagen fibers. Only hard parts, like bones and teeth, can become fossils. how collagens structural features allow fragments to survive for eons, Design of Life: Its a Matter of Physical Evidence & Logic, Judge Phil Ginn Condemns UN Demonic Proposal to Legalize Consensual Sex with Minors, Rely on Christ Instead of the Government in the Face of Religious Attacks, Says Judge Phil Ginn, Judge Phil Ginn Calls for Truth and Love in the Face of Heretical Easter Sermon, The Message of the Gospel is the Only Antidote for the Malaise So Prevalent in America Today, says Judge Phil Ginn, James D. San Antonio et al., Dinosaur Peptides Suggest Mechanisms of Protein Survival,, Thomas G. Kaye, Gary Gaugler, and Zbigniew Sawlowicz, Dinosaurian Soft Tissues Interpreted as Bacterial Biofilms,. The researchers also analyzed other fossils for the presence of soft tissue, and found it was present in about half of their samples going back to the Jurassic Period, which lasted from 145.5 million to 199.6 million years ago, Schweitzer said. "[8], Schweitzer previously announced similar discoveries in 1993. Blood-derived porphyrin proteins have also been discovered in a mid Eocene mosquito fossil. 2023 Smithsonian Magazine One (Biblical) is based on recorded history in the Bible and the other (Uniformitarian) is based on assuming that the present (processes today) is the key to the past (ancient processes) and on the hypothetical geologic time scale. To determine the ages of these specimens, scientists need an isotope with a very long half-life.

Also see: Lots of limestone New research from an interdisciplinary team of scientists provides further response to this question by demonstrating how collagens structural features allow fragments to survive for eons.1. Dinosaur soft tissues preserved as polymers - EARTH Magazine But you can disprove it. During the excavation of Ann, which took place in 2018, the skulls pieces were found scattered over a roughly 100-square-foot area with the animals back leg bones. 2007: microstructures commonly seen in modern collagen were seen in a T. rex sample. Scientists have had two decades to think about soft tissue preservation in dinosaur bones. That was about 65 million years ago. The discovery is the latest in several recent - and controversial - soft tissue finds by archaeologists: researchers last November claimed the controversial discovery of But this claim is based on experiments that are unrepresentative of the conditions under which these dinosaur remains were preserved. But does that prove that kerogens are millions of years old? He put the fossil under his microscope and found unmineralized, undecayed soft tissue. The mapping study supports the bioauthenticity of the collagen fragments. Mark Armitage participated in a dig at the Hell Creek Formation, in Montana, a world-famous dinosaur graveyard. A thigh bone from a 70-million-year-old Tyrannosaurus rex has given fossil experts an unexpected treasure: well-preserved soft tissue. Photograph B shows the demineralized bone in (A) after air drying. (2018) are, in many cases, subsequent steps of a single, unified reaction mechanism, and not separate hypotheses. As shown in Appendix B, this belief is largely due to their naturalistic worldview. Why does the Bible describe death as sleep? "Once we can get the chemistry behind some of these soft tissues, there's all sorts of questions we can ask of ancient organisms," Schweitzer said. Her first report of the preserved tissue ( Science, 25 March 2005, p. 1952) was based on preliminary tests. This means that the soft tissue is about 4.5k years old. The soft tissues are collagen, a connective protein. This forced closeness allows for broken strands to occasionally rejoin and reform the original protein. Schweitzer earned a B.S. If endogenous, putative dinosaur soft tissues should contain diagenetically unstable proteins and phospholipids, vulnerable to hydrolysis, although the released fatty "Geologic Time." Fossils represent the order of burial during the flood. However we have no reason to believe that they were not literal years, genesis is very specific, even to odd numbers. Sometimes a dinosaur carcass has been preserved as a natural mummy with widespread skin impressions. The discovery of soft tissue in dinosaur bones was unexpected and scientists have struggled to find a robust explanation. The American Biology Teacher (2021) 83 (5): 298302. The recent discovery of preserved cells and soft tissues in certain dinosaur bones seems incompatible with an age of millions of years, given the expectation that cells and soft tissues should have decayed away after millions of years. The soft material was present in pre- and post-decalcified bone. One of the most provocative pieces of evidence young-earth creationists cite for a 6,000- to 10,000-year-old Earth is the discovery of soft-tissue remains in a dinosaur specimen that dates around 68 million years old. 2017: the study done in 2009 was repeated in order to answer critics. soft tissues recovered in Montana / Nonfossil These undated photos provided by the journal Science show demineralized fragments of tissues lining the marrow cavity of a Tyrannosaurus Rex femur. Your Privacy Rights Observations on life; particularly spiritual, Being fruitful in work, service & relationships, Six reasons to be skeptical of the geologic time scale. A thigh bone from a 70-million-year-old Tyrannosaurus rex has given fossil experts an unexpected treasure: well-preserved soft tissue. But people like her never seem to question their deep time evolutionary assumptions. As the soft tissue in dinosaur bones can be explained readily under the biblical time scale, this supplies a more realistic explanation of the presence of soft tissue in dinosaur bones than the uniformitarian (geologic) time scale. News reports around the world tell of red-blood-cell-like and collagen-like structures found in 75 million year-old dinosaur bones long stored in the British Museum. They also argue that the collagen fragments derive from bacterial proteins with structural homology to collagen. Soft fibrillar bone tissue was discovered inside the fossil brow horn of a Triceratops horridus. [14][15][16] Blood-derived porphyrin proteins have also been discovered in a mid Eocene mosquito fossil. Notice that the press release admits that these biological tissues and cells exist. Dinosaur So to determine the age of sedimentary rock layers, researchers first have to find neighboring layers of Earth that include igneous rock, such as volcanic ash. The substance left behind was a stretchy material that showed blood vessels, bone-building cells known as osteocytes and other organic features when observed under Eventually, some of the blocks can fall away, leaving a smaller, more stable structure. This fall I will be presenting at the 2016 National Conference on Christian Apologetics. Soft Tissue in Dinosaur The extreme temperatures of the magma would just destroy the bones. At that time, Australia, Antarctica, New Zealand and South America were all connected in a southern landmass known as Gondwana. They seem so fresh that it appears as The most widely known form of radiometric dating is carbon-14 dating. The half-life of carbon-14 is only 5,730 years, so carbon-14 dating is only effective on samples that are less than 50,000 years old.
