Dinosaur soft tissue carbon dating

dinosaur soft tissue carbon dating

How long does soft tissue last in a fossil?

Soft tissue normally will deteriorate over time. Soft tissue should not last 65 million years, yet it has been found in a dinosaur fossil which “has” to be at least that old. This is so contrary to conventional theory that the discovery met with disbelief at first. 13, 14.

How old are carbon-14-dated dinosaur bones?

Carbon-14-dated dinosaur bones are less than 40,000 years old. Dinosaur bones with Carbon-14 dates in the range of 22,000 to 39,000 years before present, combined with the discovery of soft tissue in dinosaur bones, indicate that something is indeed wrong with the conventional wisdom about dinosaurs. However,...

How old is C-14 dating for dinosaurs?

The theoretical limit for C-14 dating is 100,000 years using AMS, but for practical purposes it is 45,000 to 55,000 years. The half-life of C-14 is 5730 years. If dinosaur bones are 65 million years old, there should not be one atom of C-14 left in them.

Why was collagen found in a dinosaur bone?

The discovery, and later confirmation, of collagen in a Tyrannosaurus-Rex dinosaur femur bone was reported in the journal SCIENCE. This is a remarkable find because collagen, being a soft tissue present in most animals, is supposed to decay in a few thousand years. Collagen is the main protein found in connective tissue of animals.

How old are soft tissue fossils?

Soft tissues have been found in numerous dinosaur and other creature’s fossils, and many of these tissue specimens have been found to contain measurable radiocarbon, Carbon-14. These Carbon-14 tests have yielded dates of only 18,000 to 50,000 thousands of years old.

Is it possible for soft tissue to survive for 80 million years?

The reality is that we don’t know, with any precision, how fast proteins degrade under the conditions found in dinosaur fossil bones. Thus, it is incorrect to claim that we know that it is impossible for soft tissue to survive in any form for 80 million years.

What happens to soft tissue during fossilization?

Unlike bones and teeth, which can survive for hundreds of millions of years, soft tissues are among the first materials to disappear during the fossilization process. Even so, scientists have found intact soft tissue in dinosaur bones before.

What other soft tissues have we found in Dinosaur remains?

We now know that DNA, collagen, elastin, and laminin have been authenticated as existing in fossil dinosaur remains as well as in other organisms supposedly predating the dinosaur era on the evolutionary time scale. What about whole soft tissues found in supposedly ancient remains? We have been finding them for years!

What did dinosaurs have in common with collagen?

Blood cells found in dino fossils. And in another fossil fragment, they found fibrous features with a banded structure similar to that seen in modern-day collagen - found in the tendons, skin and ligaments of animals.

What is the source of collagen in bones?

These were probably derived from the iron-rich blood cells of the living dinosaur and would have provided the internal environment for the preservation of collagen. Within a rib, the scientists found fragments of proteins, likely from the collagen in the bone’s vascular canals.

Can you find soft tissue in dinosaur bones?

Scientists Find Soft Tissue in 75-Million-Year-Old Dinosaur Bones. Even so, scientists have found intact soft tissue in dinosaur bones before. The most famous case dates to 2005, when Mary Schweitzer of North Carolina State University found collagen fibers in the fossilized leg bone of a Tyrannosaurus rex.

What did scientists find inside a 195 million year old bone?

Dinosaur surprise: Scientists find collagen inside a 195-million-year-old bone. A piece of the 195-million-year-old Lufengosaurus rib, where bits of collagen were found. Dinosaur paleontology has long been the domain of bones and teeth – but now soft tissues could be changing the game.
