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.

Did Mary Schweitzer discover 65 million year old dinosaur fossils?

Editor’s Note: Paleontologist Mary Schweitzer made worldwide headlines in 2005 for announcing that she had discovered soft tissue preserved in 65 million year old dinosaur fossils. Those who deny the scientific evidence for the old age of the earth have attempted to leverage this discovery to cast doubt on dating methods.

How old is the carbon 14 in dinosaur bones?

C14 is considered a fast decay, and it can only date objects that are younger than 50,000 years old. This presents a problem since dinosaurs are 65-250 million years old. That means the Carbon14 in the bones is non-existent. How do we date dinosaur bones?

What is the difference between carbon 14 dating and dinosaur 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. Dinosaur bones, on the other hand, are millions of years old -- some fossils are billions of years old.

How can you tell how old a dinosaur bone is?

The most widely known form of radiometric dating is carbon-14 dating. This is what archaeologists use to determine the age of human-made artifacts. But carbon-14 dating wont work on dinosaur bones. 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.

What is the age of a dinosaur fossil?

C14 is considered a fast decay, and it can only date objects that are younger than 50,000 years old. This presents a problem since dinosaurs are 65-250 million years old. That means the Carbon14 in the bones is non-existent.

Did Mary Schweitzer discover fresh dinosaur tissue?

That’s the title of an article in Discover magazine 1 about Dr Mary Schweitzer’s discoveries of fresh dinosaur tissue (which we’ve earlier reported on— Dinosaur bone blood cells found, Creation 16 (1):9, 1993; Sensational dinosaur blood report! 19 (4):42; 1997; Dino soft tissue find, 27 (4):7, 2005).

What did Schweitzer and Wittmeyer find in another dinosaur?

Schweitzer and Wittmeyer have now found probable blood vessels, bone-building cells and connective tissue in another T. rex, in a theropod from Argentina and in a 300,000-year-old woolly mammoth fossil. Schweitzer’s work is “showing us we really don’t understand decay,” Holtz says.

What was the first thing scientists discovered about dinosaurs?

It was big news indeed last year when Schweitzer announced she had discovered blood vessels and structures that looked like whole cells inside that T. rex bone-the first observation of its kind. The finding amazed colleagues, who had never imagined that even a trace of still-soft dinosaur tissue could survive.

Did Schweitzer prove dinosaurs had elastic skin?

Schweitzer has not proved that the elastic tissue she found actually consists of molecules from the original dinosaur. Poinar ticks off a list of tests Schweitzer could have conducted, including searching for the building blocks of proteins and then sequencing them to determine their origin.
