Blood vessels, red blood cells, and soft and stretchy ligaments were found in the bone. But people like her never seem to question their deep time evolutionary assumptions. Amino acid sequencing of several samples have shown matches with the known collagens of chickens, frogs, newts and other animals. | READ MORE. Does he face the objections to the crosslinking hypothesis presented by Dr Kevin Anderson in the link above? Schweitzer is set to search for more dinosaur soft tissue this summer. Photograph C shows regions of demineralized bone showing fibrous character (arrows). But after several years of debate, its generally agreed that the soft tissue discovered by Mary Schweitzer is authentic. These are chemical elements, like carbon or uranium, that are identical except for one key feature -- the number of neutrons in their nucleus. Red blood cells could be clearly viewed using a thrift store microscope! My two topics are The Cells Design and Dinosaur Blood and the Age of the Earth.. The recent discovery of preserved cells and soft tissues in certain dinosaur bones seems incompatible with an Fossils represent the biological evolution of species. Since the moon and the Earth probably formed at the same time, this supports the current idea of the Earth's age. Even if the individual protein strands break down, the fiber would still remain largely intact because of all the association points. They found the proteins really did come from dinosaur soft tissue. According to new research, iron In relative dating, fossils are compared to similar fossils and rocks, the ages of which are known. But as compelling as this evidence for a young earth might seem, the preservation of dinosaur soft tissue for 68 million years can be readily explained. Do proposed solutions beg the question or toss answers into the futureware bin? The half-life of the isotope being measured determines how useful it is at dating very old samples. As the award recipient Schweitzer was the keynote speaker and presented on her research. This information has also helped determine the age of the Earth itself. 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. Significantly, Landon Anderson does cite the published work by Mark Armitage and Kevin Anderson in Acta Histochemica (2013) in his list of soft tissue reports. How many are there, and which one is Jesus in? (1/2/2008) http://wrgis.wr.usgs.gov/parks/gtime/ageofearth.html, Special Offer on Antivirus Software From HowStuffWorks and TotalAV Security. This means that isotopes with a short half-life won't work to date dinosaur bones. ), 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. In most cases, microbes feast on a dead animal's soft tissue, destroying it within weeks. Where they should be three separate bones, these bones have grown together, Carrano said. That was about 65 million years ago. 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). What are the idle words referred to in Matthew 12:36? Notice that the press release admits that these biological tissues and cells exist. That idea is not considered by LAA. 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. 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 But it doesnt explain totally un-crosslinked soft dinosaur tissues (Thomas, 2019). In 2000, paleontologist Bob Harmon found a Scientists have also made improvements to the standard radiometric measurements. 15009 Lancaster Highway | Charlotte, NC 28277704-847-5600 |[emailprotected] 2022 | All Rights Reserved, Affiliation, Authorization, & Accreditation, 3 Reasons You Should Consider a Seminary Education, 8 Essential Facts for Effective Christian Apologetics, 24 Questions about Christianity & Social Justice. It sounds pretty mystical to appeal to futureware. Version 1.2 (1/2/2008) http://pubs.usgs.gov/gip/geotime/, USGS. 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. The stretchy material, which The biblical explanation allows for catastrophic events (such as the flood of Noah), whereas the Uniformitarian explanation minimizes the role of catastrophic events (because it has a preference for gradual events). Her first report of the preserved tissue ( Science, 25 March 2005, p. 1952) was based on preliminary tests. Importantly, Schweitzer and her colleagues have figured out how to remove the iron from their samples, which enables them to analyze the original proteins. Later research by Kaye et al. Havent you seen bicycles, tanks and Model T Fords before?. At that time, Australia, Antarctica, New Zealand and South America were all connected in a southern landmass known as Gondwana. Do some careful reading and see whether his chemical framework for soft tissue preservation makes plausible chemical sense and answers all the objections to the crosslinking hypothesis brought up by Kevin Anderson and Brian Thomas, or whether LAA is desperately looking for rescue devices to preserve deep time. 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. Why was Judah the most prominent tribe of Israel? Read on to see what it takes to date a fossil and what volcanic ash has to do with it. How does he deal with it? Scientists have had two decades to think about soft tissue preservation in dinosaur bones. Some day over the rainbow, Ill prove all; Does it render tissue impenetrable to cosmic rays, radon in the soil, or bioturbation? Part of HuffPost Science. Scientists have excavated the first near-complete skull of a sauropod to ever be found in Australia. Perhaps both the dinosaur tissue and kerogens are young. These two hypotheses, taken together, dont answer every question regarding soft tissue preservation in deep time. [12] Atoms may have an equal number of protons and neutrons. Follow us @livescience, Facebook & Google+. The extreme temperatures of the magma would just destroy the bones. "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. [13] The extraction of protein, soft tissue, remnant cells and organelle-like structures from dinosaur fossils has been confirmed. From the paper by Landon Anderson. Subjects: Scientific Evidence for a Young Earth? It potentially describes the preservation, says Landon Anderson of NC State. A chemical framework for the preservation of fossil vertebrate cells and soft tissues (Landon A. Anderson, Earth Science Reviews, May 2023 issue). "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?' The research, headed by Mary Schweitzer, a molecular paleontologist at North Carolina State University, explains how proteins and possibly even DNA can survive millennia. In many cases, they are one and the same.. Microscopy images of "soft tissues" isolated from bones of the Cretaceous dinosaur Brachylophosaurus canadensis (MOR 2598 and GPDM 328), along with extant Armitages attorney said that the state would never have paid such a huge sum unless it was very concerned about losing in court. And Schweitzer has even recovered fragments of the more fragile and complex molecule, DNA. Be especially wary of distractions and sidesteps. In addition, the oldest known moon rocks are 4.5 billion years old. (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. 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 Fossil age is determined using two methods, relative dating and absolute dating. Dont be thrown off balance by acronyms (ITMs, KLMs, MLMs, etc.) So believing proteins could last for tens of millions of years takes enormous faith. Photograph B shows the demineralized bone in (A) after air drying. 5. For example, see these RTB resources for probable explanations for the T. rex soft tissue. Ever since Mary Schweitzer found soft, stretchy tissue in a T. rex fossil in 2004, scientists have been trying to come to grips with how some biological tissues and cells could preserve within ancient critters. 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. In fact, the chemistry from this paper potentially describes preservation for a variety of original cellular tissues, including vertebrates and other organisms trapped within amber, carbonized traces of ancient feathers and skin, and even dinosaur mummies.. As shown in Appendix B, this belief is largely due to their naturalistic worldview. A thigh bone from a 70-million-year-old Tyrannosaurus rex has given fossil experts an unexpected treasure: well-preserved soft tissue. The same is true if you take a block away from one of the pyramid's sides, making the rest unstable. Using the basic ideas of bracketing and radiometric dating, researchers have determined the age of rock layers all over the world. Cookie Policy So it cannot block water and oxygen indefinitely, which readily react with fragile molecules even underground. Chronological index. ]]>. [6], Schweitzer was the first researcher to identify and isolate soft tissues from an ancient fossil bone. 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. Such implications that are immediately apparent from examining the chemical framework are discussed. At the end of the Cretaceous Period, dinosaurs went extinct. Why was Noahs family saved while the rest died in the flood. [14][15][16] Blood-derived porphyrin proteins have also been discovered in a mid Eocene mosquito fossil. Collagens abundance further explains its presence in dinosaur fossils. They also argue that the collagen fragments derive from bacterial proteins with structural homology to collagen. 9/28/1991. 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? Fossils, however, form in sedimentary rock -- sediment quickly covers a dinosaur's body, and the sediment and the bones gradually turn into rock. 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. They then tested the iron-as-preservative idea using modern ostrich blood vessels. By using radiometric dating to determine the age of igneous brackets, researchers can accurately determine the age of the sedimentary layers between them. They soaked one group of blood vessels in iron-rich liquid made of red blood cells and another group in water. But there are a number of different chemical pathways that can result in crosslinking. 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. It forms minuscule iron nanoparticles and also generates free radicals, which are highly reactive molecules thought to be involved in aging. Heads I win, tails you lose Both of these ages are assigned according to the geological time scale. Where they should be three separate bones, these bones have grown together, Carrano said. The controversial discovery of 68-million-year-old soft tissue from the bones of a Tyrannosaurus rex finally has a physical explanation. As Ive previously pointed out, it is not all that surprising that collagen (or at least fragments of it) could survive 68 million years in an environment devoid of water, oxygen, and microbes given its structure. The fossil horn was found in the famous Hell Creek Formation near Glendive, Montana. [17], In the developing field of paleoproteomics, Schweitzer has also discovered that iron particles may play a part in the preservation of soft tissue over geologic time. Scientists can't tell whether the clock ran down a few days or millions of years ago. AiGUSAs Dr. David Menton 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. Scientists have had two decades to think about soft tissue preservation in dinosaur bones. | 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. If endogenous, putative dinosaur soft tissues should contain diagenetically unstable proteins and phospholipids, vulnerable to hydrolysis, although the released fatty You can't predict when a specific unstable atom, or parent, will decay into a stable atom, or daughter. Not only is Ann the first Diamantinasaurus uncovered with a mostly preserved skull, but its also the first fossil of the species with a preserved back foot, per the statement. These soft tissues are composed mainly of proteins, which are believed to completely degrade within about four million years. "Understanding Evolution for Teachers: Radiometric Dating." According to new research, iron in the dinosaur's body preserved the tissue before it could decay. And tests seemed to confirm the presence of collagen. "Determining the Age of Rocks and Fossils." What did David mean when he wrote that he was fearfully made in Psalm 139:14? 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?
