Maybe it was just a few thousand years old — trapped by sediment in a catastrophic worldwide flood and fossilized. Since her initial discovery, Schweitzer, a molecular paleontologist at North Carolina State University, has found red blood cells, blood vessels, bone cells and even hemoglobin and collagen. A supposedly million-year-old duck-billed dinosaur bone has also yielded soft tissue. The Christian Science Monitor reported this January that scientists found collagen, a protein basic to animal tissue, in an allegedly million-year-old fossil of a Lufengosaurus dinosaur in China. But Schweitzer, a conservative evangelical Christian who adheres to evolutionary theory, floated the theory in that iron may have preserved the soft tissue much like formaldehyde. If shown to be true, her theory would take wind out of the sails of the young earth Christians. Schweitzer got her start in paleontology after studying molecular biology.

Why is carbon-14 dating not used for dating dinosaur bones/fossils?

The main point of the debate seems to be the following: Over the past decades, several research groups of self-proclaimed creationist scientists have claimed discoveries of dinosaur bones that they have managed to date, using radiocarbon dating methods , at some age which is a lot below the ‘usual’ i. The age that these groups claim to find is usually on the order of thousands or tens of thousands of years old. The particular example you bring up is one of the most famous such cases.

Dinosaur bones have been dated, based on the half life of certain elements, at millions of years. Actually, most dates for dinosaurs are done by geological column dating. Scientists see what depth the bones were found, and translate it to a date based on uniformitarian assumptions. You’ve surely seen a geologic column picture with dates to the side.

Definition Triceratops skeleton, Natural History Museum of Los Angeles County Under phylogenetic nomenclature , dinosaurs are usually defined as the group consisting of Triceratops , Neornithes , their most recent common ancestor MRCA , and all descendants. In traditional taxonomy, birds were considered a separate class that had evolved from dinosaurs, a distinct superorder.

However, a majority of contemporary paleontologists concerned with dinosaurs reject the traditional style of classification in favor of phylogenetic taxonomy; this approach requires that, for a group to be natural, all descendants of members of the group must be included in the group as well. Birds are thus considered to be dinosaurs and dinosaurs are, therefore, not extinct.

Birds are classified as belonging to the subgroup Maniraptora , which are coelurosaurs , which are theropods, which are saurischians , which are dinosaurs. Norman, and Paul M. Barrett in suggested a radical revision of dinosaurian systematics.

Posted on June 23, 3 Comments Dinosaur bones are supposed to be around 65 million years old, right? But what happens if you date them using carbon dating, which is theoretically useful for dating organic materials that are much younger, having died up to 50, years ago? This should be a no-brainer, right? The theory predicts that the test results should say that the bones are at least 50, years old.

Q: Unreliable carbon dating puts dinosaur bones over years old My goodness. That would be very unreliable indeed. Radiocarbon dating cannot be used to date anything that hasn’t been alive in the last 50, years or so. It works by measuring the carbon remaining in a once living thing.

James Scott What in the world is this supposed to mean?: The way that the scientific method works is that when scientists discover any empirical data that contradicts their theory or hypothesis, scientists become obliged to either throw out their theory or revise it, so that their theory conforms to the facts. They are not supposed to reinterpret the facts so that the facts conform to their theory.

That would be a violation of the scientific method! And that is precisely what I detect here. Instead of drawing an inference to the best explanation which would be that these bones are not 75 million years old, they are absurdly claiming that it is somehow possible after all for soft tissue and red blood cells to be preserved in natural volatile conditions for over 75 million years.

Give me a break. Llamaman the cells are preserved within bone pretty much a sealed canister and encased in rock sorry but what part of that is volatile conditions? Jon Tennant James, thanks for your question. Susie and the other researchers are going to use this discovery of a basis to investigate your main question there!

Ancient Dinosaur Depictions

The first 3 dinosaur fossils led to the recognition of a new group of animals, the dinosaurs. The first nearly-complete dinosaur skeleton in New Jersey spurs modern paleontology. People have been finding dinosaur fossils for hundreds of years, probably even thousands of years. The Greeks and Romans may have found fossils, giving rise to their many ogre and griffin legends.

* Studies Carbon Dating Mosasaur and Dinosaur Bones: Saving RSR a lot of money, including in connection with soft tissue, scientists have begun reporting carbon dating of Mesozoic-layer (not era) fossil bones.

This is what archaeologists use to determine the age of human-made artifacts. But carbon dating won’t work on dinosaur bones. The half-life of carbon is only 5, years, so carbon dating is only effective on samples that are less than 50, years old. Dinosaur bones, on the other hand, are millions of years old — some fossils are billions of years old. To determine the ages of these specimens, scientists need an isotope with a very long half-life. Some of the isotopes used for this purpose are uranium , uranium and potassium , each of which has a half-life of more than a million years.

Unfortunately, these elements don’t exist in dinosaur fossils themselves.

How Do Scientists Determine the Age of Dinosaur Bones?

Carbon , Radiometric Dating and Index Fossils Carbon dating is used to determine the age of biological artifacts up to 50, years old. This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be millions of years old. This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers.

Adapted from Dinosaurs: The Very Latest Information and Hands-On Activities From the Museum of the Rockies, by Liza Charlesworth and Bonnie Sachatello-Sawyer.A Scholastic Professional Book. Way back in , Robert Plot, the curator of an English museum, described and drew a thigh bone that he believed belonged to a giant man.

Jack Cuozzo click to enlarge. It was taken by the author in Bernifal Cave, one of the caverns in France that is renowned for Neanderthal art. Mammoth drawings are not unusual in such cave art, but the depiction of an apparent theropod dinosaur is remarkable. In BC, under the reign of King Nebuchadnezzar, a Babylonian artist was commissioned to shape reliefs of animals on the structures associated with the Ishtar Gate.

Many centuries later German archaeologist Robert Koldewey stumbled upon the blue-glazed brick and that gate was rediscovered in The animals appear in alternating rows with lions, fierce bulls rimi or reems in Chaldean , and curious long-necked dragons sirrush. The lions and bulls would have been present at that time in the Middle East.

C-14 Dating of Dinosaur Bones

Tweet NaturalNews A recent archaeological discovery that throws a wrench into the conventional theory of evolution has reportedly cost a California professor his job. Mark Armitage, a former scientist at California State University, Northridge CSUN , was reportedly fired after claiming to have unearthed a dinosaur fossil that still contains soft, flexible tissue, suggesting that it can’t be millions of years old.

A year veteran in his field, Armitage has published many studies over the years in peer-reviewed journals.

Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.

Is it because the results routinely show man and dinosaurs lived at the same time, thus totally destroying the religion of evolutionism, or is there another reason? Why are the bones assumed to be millions of years old? And if they are, why do they have C14 in them according to those that have tested them? Anything even over , years old should have no detectable C14 in them.

Scientists routinely use C14 dating on the bones of mammoths, giant sloths, saber tooth tigers, and other similar ancient animals. Why when they show C14 in them, that indicates they are tens of thousands of years old according to the test; however, if the exact same tests are done on the bones of
