Buy Dinosaur Shakespeare: To Date or Not To Date?

Although ancient DNA could not be used to bring dinosaurs back to life, scientists believe they could use the DNA to trace the evolution of life. Scientists from the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences CAS , and Mary Schweitzer, of North Carolina State University in the United States, have discovered evidence of fossilized cell nuclei and chromosomes within preserved cartilage of baby duck-billed dinosaurs, dating back 75 million years. Scientists discovered dinosaur fossils found in northwest Montana. After the analysis, scientists found that the dinosaur belongs to the genus Hypacrosaurus , and comes from a nesting ground in Late Cretaceous sediments. In , American paleontologist Jack Horner became famous, providing the evidence that some dinosaurs cared for their young. Scientists, in this study, conducted microscopic analyses of skull fragments from these nestling dinosaurs. In one part, she saw some exquisitely protected cells inside calcified cartilage on the edges of a bone. Two cartilage cells were as yet connected by an intercellular bridge, morphologically predictable with the end of cell division.

How and why to date a dinosaur

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? The bone was 68 million years old, and conventional wisdom about fossilization is that all soft tissue, from blood to brains , decomposes. Only hard parts, like bones and teeth, can become fossils.

Carbondated dinosaur bones are less than 40, years old. Researchers have found a reason for the puzzling survival of soft tissue and DNA fragments in dinosaur bones – the bones are younger than anyone ever guessed. Carbon C dating of multiple samples of bone from 8 dinosaurs found in Texas, Alaska, Colorado, and Montana revealed that they are only 22, to 39, years old. Since dinosaurs are thought to be over 65 million years old, the news is stunning – and more than some could tolerate.

After the AOGS-AGU conference in Singapore, the abstract was removed from the conference website by two chairmen because they could not accept the findings. Unwilling to challenge the data openly, they erased the report from public view without a word to the authors. When the authors inquired, they received this letter:. They did not look at the data and they never spoke with the researchers.

They did not like the test results, so they censored them. Carbon is considered to be a highly reliable dating technique. It’s accuracy has been verified by using C to date artifacts whose age is known historically. The fluctuation of the amount of C in the atmosphere over time adds a small uncertainty, but contamination by “modern carbon” such as decayed organic matter from soils poses a greater possibility for error.

Brain tissue, unlike durable bones and teeth, is often one of the first parts of the body to decay. The finding could also help brains paleontologists to spot more fossilized dinosaur brains, reveals that they first to look did clues in unassuming clumps of dirt, said Lawrence Witmer, a professor of anatomy at Reveals University’s Heritage College of Osteopathic Medicine, who was not involved with the new research.

DINOSAUR DATING?

Fossils themselves, and the sedimentary rocks they are found in, are very difficult to date directly. These include radiometric dating of volcanic layers above or below the fossils or by comparisons to similar rocks and fossils of known ages. Knowing when a dinosaur or other animal lived is important because it helps us place them on the evolutionary family tree. Accurate dates also allow us to create sequences of evolutionary change and work out when species appeared or became extinct.

There are two main methods to date a fossil. These are:.

The Age of Dinosaurs was so many millions of years ago that it is very difficult to Scientists find out the age of a dinosaur fossil by dating not only the rocks in.

November 14, You might think dating dinosaurs would be an easy task, but in reality it’s actually quite difficult. We date dinosaurs based on where we find their fossils, using the ages of the rocks that they’re found in. This means that the ‘ages’ of different dinosaurs is actually indirect and constrained by how well we’re able to date the rocks they were found in.

Ghosts in the machine. As well as this, we know that the occurrences of dinosaur fossils are not accurate representations of their age either. If we know one dinosaur species A was around million years ago, and its closest relative species B known only million years ago, then species B must have existed million years earlier too as they must have shared an origination time due to the way speciation works — we just haven’t found any fossils of it during this 20 million year gap though.
