Fossils of a new dromaeosaur date to the end of the Age of Dinosaurs
Carbondated dinosaur bones are less than 40, years old. Researchers technique found a reason for the puzzling survival of soft dating and collagen in dinosaur bones – the bones are younger than anyone ever guessed. Carbon C dating of multiple samples of bone dating 8 dinosaurs found in Fossils, Alaska, Colorado, and Montana revealed that they are only 22, to 39, years old. Since dinosaurs dating thought to be over 65 million years old, the news is stunning – and more than some can tolerate. After the AOGS-AGU conference in Singapore, the abstract was removed from the conference website by two chairmen because they could not accept new 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 dinosaur this letter: They did not look at the data and they never fossils with the researchers. They did not like the test results, so fossils censored them.

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.
And we call these ghost ranges or lineages. What these ghost ranges do, when combined with trees that illustrate the relationships between different organisms, is alter the timings or dates of important events based on exactly how we time-scale the trees and the ghost and true ranges of species. This uncertainty in dating and the methods we use actually has quite important implications for significant events in the evolutionary history of dinosaurs.
A team led by Graeme Lloyd of Macquarie University, Australia, recently set out to investigate three questions:. What was the origination time for Dinosauria all dinosaurs?

Finding measurable C14 in the bones would therefore invalidate the consensus belief that dinosaurs lived and died over 65 million years ago. Secular paleontologists consider it a waste of time to test for C14 in dinosaur bone. But if you do, you never know. In the spring issue of their peer-reviewed CRS Quarterly , they published a special report with results of their iDINO project : an investigation into soft tissue remains in dinosaur bones. This issue was prepared and printed before the announcement in Nature Communications.
The bombshell announcement is that measurable C14 has been found in dinosaur bones. Brian Thomas and Vance Nelson report:. Measurable amounts of radiocarbon have been consistently detected within carbonaceous materials across Phanerozoic strata. Under uniformitarian assumptions , these should no longer contain measurable amounts of radiocarbon.

The age of fossils can be determined using stratigraphy, biostratigraphy, and radiocarbon dating. Paleontology seeks to map out how life evolved across geologic time. A substantial hurdle is the difficulty of working out fossil ages.

Who Discovered the First Dinosaur Bone?
Carbon 14 C dating is used to establish the age of skeletons, fossils, and other items composed of material that was once alive. Very precise analysis from modern mass spectrometers can establish the date the living material in the sample stopped taking in carbon from the environment the point of death.
Because C has such a short half-life radioactively decaying into Nitrogen 14 , all detectable C should have disappeared well before , years. But careful analysis by researchers has substantiated the presence of Carbon 14 in dinosaur bones. Critics suggested that the samples became contaminated with modern Carbon

Are you afraid of snakes? What about lizards and other reptiles? It’s understandable to be cautious around such creatures if you encounter them in the wild. But what if you had bigger and fiercer creatures to worry about?
Radiocarbon dating methods. Dinosaur for ensuring RC fossils are valid in situations demanding a careful investigation or try to pinpoint an absolute RC date.
And the result of this accepted method dates dinosaur fossils to around 68 million years old. However: Consider the C decay rate. The theoretical limit for C dating is , years using AMS, but for practical purposes it is 45, to 55, years. If dinosaur bones are 65 million years old, there should not be one atom of C left in them. Dinosaurs are not dated with Carbon, yet some researchers have claimed that there is still Carbon in the bones.
So what needs to be done about this inconsistency?

One of the tricks you learn hunting dinosaurs in Canada is to look for orange. Dinosaur bones are dull browns, tans, and greys. Walk over and you may well find a dinosaur bone weathering out. The orange is lichen, growing on the bone.

By Carolyn Gramling. March 26, at pm. A wolf-sized warrior, kin to the fierce, feathered Velociraptor , prowled what is now New Mexico about 68 million years ago. Dineobellator notohesperus was a dromaeosaur, a group of swift, agile predators that is distantly related to the much larger Tyrannosaurus rex. The discovery of this new species suggests that dromaeosaurs were still diversifying, and even becoming better at pursuing prey , right up to the end of the Age of Dinosaurs, researchers say March 26 in Scientific Reports.
That age came to an abrupt close at the end of the Cretaceous Period about 66 million years ago, when a mass extinction event wiped out all nonbird dinosaurs. The new find suggests otherwise. Analyses of muscle attachment sites on the fossilized forelimbs suggest the dinosaur was unusually strong for a dromaeosaur, with a very tight grip in its hands and feet. That grip, Jasinski says, was likely stronger than that of its famous kinfolk, Velociraptor and Utahraptor , giving the new species extra weaponry in its pursuit of prey.
Like many other dromaeosaurs, D.
