[14][15][16] Blood-derived porphyrin proteins have also been discovered in a mid Eocene mosquito fossil. Tracy V. Wilson Large numbers of collagen fibrils in turn assemble, with the aid of other proteins, into collagen fibers. Soft fibrillar bone tissue was discovered inside the fossil brow horn of a Triceratops horridus. The soft tissues found by Schweitzer and others are not mineral replacements of soft tissue; they are the original soft tissue. Under the biblical explanation of geologic history (see Appendix B), the dinosaurs were buried during the global flood about 4.5k years ago. Where they should be three separate bones, these bones have grown together, Carrano said. By using radiometric dating to determine the age of igneous brackets, researchers can accurately determine the age of the sedimentary layers between them. The most widely known form of radiometric dating is carbon-14 dating. Scientists have had two decades to think about soft tissue preservation in dinosaur bones. I still havent (Service, 2017). When paleontologist Mary Schweitzer found soft tissue in a Tyrannosaurus rex fossil, her discovery raised an obvious question -- how the tissue could have survived so long? So far, there is every indication that the dinosaur soft tissuesincredible as it seemsare real biological leftovers from their once-living hosts. Do proposed solutions beg the question or toss answers into the futureware bin? Numerous collagen triple helices assemble in a staggered fashion to form a larger structure called a collagen fibril. Based on the analysis of these samples, scientists estimate that the Earth itself is about 4.5 billion years old. For example, see these RTB resources for probable explanations for the T. rex soft tissue. 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 in 2015 fibers and cellular structures were discovered preserved in 75 million year old dinosaur specimens. ]]>. This is what archaeologists use to determine the age of human-made artifacts. The research, headed by Mary Schweitzer, a molecular paleontologist at North Carolina State University, explains how proteins and possibly even DNA can survive millennia. National Conference on Christian Apologetics. Schweitzer was able to retrieve proteins from this femur in 2007. According to new research, iron Look at how he begs the question: The fossil fuels used daily by society consist of original biomolecules of ancient plants and microorganisms that have been chemically transformed into carbonaceous macromolecules referred to as kerogens (Tissot and Welte, 1984; Tegelaar et al., 1989; Vandenbroucke and Largeau, 2007). (1/2/2008) http://evolution.berkeley.edu/evosite/evo101/IIE1aAtomicclocks.shtml, USGS. I have heard there are seven heavens. 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. [See Images of a Near-Complete T. rex]. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Scripture index This information has also helped determine the age of the Earth itself. So it cannot block water and oxygen indefinitely, which readily react with fragile molecules even underground. The discovery of soft tissue in dinosaur bones by Mary Schweitzer was unexpected and scientists have struggled to find a robust explanation. Dinosaurs' iron-rich blood, combined with a good environment for fossilization, may explain the amazing existence of soft tissue from the Cretaceous (a period that lasted from about 65.5 million to 145.5 million years ago) and even earlier. A thigh bone from a 70-million-year-old Tyrannosaurus rex has given fossil experts an unexpected treasure: well-preserved soft tissue. The controversial discovery of 68-million-year-old soft tissue from the bones of a Tyrannosaurus rex finally has a physical explanation. Yeah, those frogs were preserved via crosslinking with formaldehyde. Armitage was fired because of the intellectual intolerance that other scientists felt toward creationists. How Are Dino Tissues Preserved in Deep Time? Photograph B shows the demineralized bone in (A) after air drying. 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. Soft tissue impressions are usually of the skin. A Brief History of Steamboat Racing in the U.S. Texas-Born Italian Noble Evicted From Her 16th-Century Villa. The same is true if you take a block away from one of the pyramid's sides, making the rest unstable. This entry was posted on November 4, 2019 by George Hawke. This is what archaeologists use to determine the age of human-made artifacts. Which needs less demystifying? The structures appear to be genuine remnants of soft tissue; they are not fossilised. Perhaps both the dinosaur tissue and kerogens are young. They've even found chemical reactions consistent with the presence of DNA, though Schweitzer is quick to note that she hasn't proven DNA is really present. 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. Does he face the objections to the crosslinking hypothesis presented by Dr Kevin Anderson in the link above? Draw the Dinosaur's Face. Even if the individual protein strands break down, the fiber would still remain largely intact because of all the association points. And so all of you skeptics eat crow; away with you! Service R F , 2017, I dont care what they say about me: Paleontologist stares down critics in her hunt for dinosaur proteins, Science, Portland, Oregon, 13 Sep, 2017. Three options present themselves for the presence of molecules and blood vessels in creatures that purportedly passed on eons ago. As remarkable as the discovery of soft tissue in dinosaur fossils seems to be, it cannot be used to argue legitimately for a young earth. Rare 95-Million-Year-Old Dinosaur Skull Uncovered in Australia. The bone was 68 million years old, and conventional wisdom about fossilization is that all soft tissue, from blood to brains, decomposes. Follow Stephanie Pappas on Twitter and Google+. 9/28/1991. Blood vessels, red blood cells, and soft and stretchy ligaments were found in the bone. Its interesting to note that scientists are exploring the second alternative, but not the first one! Appendix A: A summary of Mary Schweitzers research (Service, 2017). Such implications that are immediately apparent from examining the chemical framework are discussed. And tests seemed to confirm the presence of collagen. Exercise: LAAs paper is open-access. Heads I win, tails you lose Collagen fibers comprise one of the chief components of connective tissue, are embedded in the bone matrix, and help form blood vessels. Researchers estimate Ann was likely about 50 feet from head to tail. You cant prove something is true. Then a blatant assertion is made to sweep away the issue: Because we didnt realize that these processes could come from the same starting place and share a step, the hypotheses have been presented as separate, Anderson says. How do scientists know the bones are really 68 million years old? At that time, Australia, Antarctica, New Zealand and South America were all connected in a southern landmass known as Gondwana. 5. Blood-derived porphyrin proteins have also been discovered in a mid Eocene mosquito fossil. | READ MORE. Language links are at the top of the page across from the title. The mapping study supports the bioauthenticity of the collagen fragments. [5], In 2000, Bob Harmon, chief preparator of paleontology at the Museum of the Rockies, discovered a Tyrannosaurus skeleton in the Hell Creek Formation in Montana. The bones of these various specimens are articulated, not scattered, suggesting they were buried quickly. 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. Fossils can't form in the igneous rock that usually does contain the isotopes. 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. Evidence for the extraction of short segments of ancient DNA from dinosaur fossils has been reported on two occasions. Other techniques include analyzing amino acids and measuring changes in an object's magnetic field. Red blood cells could be clearly viewed using a thrift store microscope! "How do geologists date rocks? Collagens abundance further explains its presence in dinosaur fossils. 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. Unfortunately, these elements don't exist in dinosaur fossils themselves. After a two-year retrieval process, Jack Horner, director of the Museum, gave the femur bone to Schweitzer. Some of the isotopes used for this purpose are uranium-238, uranium-235 and potassium-40, each of which has a half-life of more than a million years. (2018) are, in many cases, subsequent steps of a single, unified reaction mechanism, and not separate hypotheses. The discovery of Ann is helping uncover more details about D. matildae. [11] published in PLoS ONE (30 July 2008) challenged the claims that the material found is the soft tissue of Tyrannosaurus. The window between 100 and 95 million years ago was one of the warmest in Earths geologically recent history, meaning that Antarctica, which was more or less where it is now, had no ice, Poropat says in a statement. [13] The extraction of protein, soft tissue, remnant cells and organelle-like structures from dinosaur fossils has been confirmed. In recent years, researchers have found 1) epithelial cell and osteoclast remnants; 2) the remains of blood vessels, and 3) heme, and hemoglobin components in the partially fossilized Tyrannosaurus rex femur. (LogOut/ Dinosaur bones, on the other hand, are millions of years old -- some fossils are billions of years old. Let him consider seriously the possibility that dinosaur soft tissue is probably only a few thousand years old and watch him get fired real fast. (1/2/2008) http://museumvictoria.com.au/prehistoric/what/fossilage.html#absolute, University of California at Berkeley. This is about 20,000 times older than the biblical explanation, which is a huge difference (more than 4 orders of magnitude). "The problem is, for 300 years, we thought, 'Well, the organics are all gone, so why should we look for something that's not going to be there?' (1/2/2008) http://space.newscientist.com/article/mg13117884.900-rock-of-ages--cleft-by-laser-if-you-want-to-date-a-rockget-a-laser-thats-the-message-for-geologists-interested-in-the-preciseageof-anything-from-moon-rocks-to-hominid-fossils-.html, Museum Victoria. 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. "I'd like to find a honking big T. rex that's completely articulated that's still in the ground, or something similar," she said. But after a volunteer found a bone that turned out to be part of the brain case, Poropat tells the Guardian, that then made all the other bits fall into place.. For a scientist committed all his life to Deep Time, stretchable soft tissue is hard for someone like Landon Anderson to accept in bones believed to be tens of millions of years old. 2009: protein (collagen) fragments were isolated from a 80 million year old (geologic time scale) hadrosaur fossil. Even a polymer shield strong enough to resist microbes would develop cracks. The discovery is the latest in several recent - and controversial - soft tissue finds by archaeologists: researchers last November claimed the controversial discovery of Radiometric dating isn't the only method of determining the age of rocks. And they need to be tested quickly, as soft tissue could degrade once exposed to modern air and humidity. While the oldest known rocks on Earth are about 3.5 billion years old, researchers have found zircon crystals that are 4.3 billion years old [source: USGS]. These regions are the most protected within the collagen fiber. They also argue that the collagen fragments derive from bacterial proteins with structural homology to collagen. Have evolutionists and believers in Deep Time been able to get a grip? Scientists who had to break a dinosaur bone to remove it from its sandstone location say they have recovered 70-million-year-old soft tissues from inside the bone. But this claim is based on experiments that are unrepresentative of the conditions under which these dinosaur remains were preserved. Traces of dino blood, soft tissue found even in junk bones New Scientist. "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. Yes, proteins do break down into amino acids or peptides that crosslink to form N-heterocyclic polymers. By entering your email and clicking Sign Up, you're agreeing to let us send you customized marketing messages about us and our advertising partners. Atoms may have an equal number of protons and neutrons. In most cases, microbes feast on a dead animal's soft tissue, destroying it within weeks. They then tested the iron-as-preservative idea using modern ostrich blood vessels. 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. 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,. Absolute dating, on the other hand is used to calculate the precise age of fossils through radiometric dating. 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. 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. really did come from dinosaur soft tissue, Paleo-Art: Illustrations Bring Dinosaurs to Life, Dinosaur Detective: Find Out What You Really Know. 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). Another alternative is that its not really soft tissue, but even hard-core evolutionists agree thats what it is. But it doesnt explain totally un-crosslinked soft dinosaur tissues (Thomas, 2019). He put the fossil under his microscope and found unmineralized, undecayed soft tissue. The ratio of parents to daughters can tell the researcher how old the specimen is. Scientists have excavated the first near-complete skull of a sauropod to ever be found in Australia. Dont be thrown off balance by acronyms (ITMs, KLMs, MLMs, etc.) Why was Noahs family saved while the rest died in the flood. Subjects: Scientific Evidence for a Young Earth? Follow us @livescience, Facebook & Google+. This fall I will be presenting at the 2016 National Conference on Christian Apologetics. So believing proteins could last for tens of millions of years takes enormous faith. But for some people, the discovery raised a different question. But you can disprove it. Her first report of the preserved tissue ( Science, 25 March 2005, p. 1952) was based on preliminary tests. Also proteins like collagen, hemoglobin, osteocalcin, actin, and tubulin were found. Scientists at Imperial College London have discovered what appear to be the remnants of soft tissue and red blood cells in poorly preserved dinosaur bones dating back 75 million years. All rights reserved. Scientists have had two decades to think about soft tissue preservation in dinosaur bones. 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. To determine the ages of these specimens, scientists need an isotope with a very long half-life. Both of these ages are assigned according to the geological time scale. 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. TUESDAY, SEPTEMBER 01, 2009. 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. Controversial T. Rex Find Finally Has An Explanation, Copyright 2013 LiveScience, a TechMediaNetwork company. Still, Morris question is not unreasonable. At least six possible explanations (including bacterial contaminants) have been suggested for this preservation of soft tissue in dinosaur bones, but they have all been refuted (Thomas, 2019). If the fragments were due to contamination, they should have mapped randomly onto all regions of the collagen fibers. rex femur onto molecular models of human and rat collagen fibers. Since the moon and the Earth probably formed at the same time, this supports the current idea of the Earth's age. Biblical explanation The global flood about 4.5k years ago and associated tectonic activity and volcanism produced enormously thick sequences of sedimentary rocks over a short period of time. These undated photos provided by the journal Science show demineralized fragments of tissues lining the marrow cavity of a Tyrannosaurus Rex femur. The resemblances between the skulls of Diamantinasaurus and the similarly aged Sarmientosaurus from southern South America are pretty striking.. Somewhere over the rainbow, my views true; Microscopy images of "soft tissues" isolated from bones of the Cretaceous dinosaur Brachylophosaurus canadensis (MOR 2598 and GPDM 328), along with extant As the award recipient Schweitzer was the keynote speaker and presented on her research. On the dig he and others uncovered the largest Triceratops horn ever found at that location. How to read the Bible in chronological order. This news coincides with the release of the film Jurassic World, in which fictional scientists resurrect dinosaurs using dino DNA that "iron chelators" somehow preserved for millions Eight protein fragments were found from a 80 million year old (geologic time scale) hadrosaur fossil. But a surprising number of fossil specimens also contained soft tissues, including structures resembling blood vessels, tubular nerve projections, collagen and Amino acid sequencing of several samples have shown matches with the known collagens of chickens, frogs, newts and other animals.
