Dating Dinosaur Fossils

The team has been searching under the high summer sun without success for the fossil-rich strata that braid through the arid rangeland here.
Several tests were done by the University of Georgia using accelerator mass spectrometry. The age for all these fossils was found to be less than 50, years. Each of the two thousand meeting participants was given a disc which included the abstract of the carbon dating report. However, the abstract of the Miller presentation was removed from the website for the conference. If the accepted ages of millions of years for dinosaurs were to be found to be in error, this would be a problem to evolution.
The dinosaur dates reported below and discussed in the AOGS paper discussed throughout this article, included triceratops, hadrosaur, allosaurus, and acrocanthasaurs.
Dinosaur fossil dating back 166 million years discovered on Isle of Eigg
A new species of dinosaur believed to have lived million years ago and estimated to have been up to four metres in length has been discovered on the Isle of Wight. Four bones found at the popular seaside resort of Shanklin last year belong to a new species of theropod, palaeontologists from the University of Southampton have said. Vectaerovenator inopinatus belongs to a group of dinosaurs that includes Tyrannosaurus rex, and its remains are currently being displayed at the Dinosaur Isle Museum in Sandown on the south-east coast of the Isle of Wight.
But what other dinosaur remains have been discovered in Britain – and when exactly did the prehistoric creatures roam around on our lands?
Fossils are the remains, imprints, and traces of once-living organisms Most of the actual dinosaur bones which have been discovered to date have been.
Philip J. The American Biology Teacher 1 February ; 82 2 : 72— The recent discovery of radiocarbon in dinosaur bones at first seems incompatible with an age of millions of years, due to the short half-life of radiocarbon. However, evidence from isotopes other than radiocarbon shows that dinosaur fossils are indeed millions of years old.
Fossil bone incorporates new radiocarbon by means of recrystallization and, in some cases, bacterial activity and uranium decay. Because of this, bone mineral — fossil or otherwise — is a material that cannot yield an accurate radiocarbon date except under extraordinary circumstances. Science educators need to be aware of the details of these phenomena, to be able to advise students whose acceptance of biological evolution has been challenged by young-Earth creationist arguments that are based on radiocarbon in dinosaur fossils.
The recent discovery of radiocarbon in dinosaur fossils has the potential to generate much puzzlement, because radiocarbon has a half-life too short for measurable amounts of original radiocarbon to remain in fossils that are millions of years old. Many of the other dinosaur-based anti-evolution arguments from YEC authors are less worrisome, because they are plainly absurd e.
That is because students and science educators often lack knowledge of the finer details of radiocarbon dating and the fossilization process that show how radiocarbon in dinosaur bones is consistent with an age of millions of years. Appropriate responses to such YEC arguments are therefore not always at hand.
Dinosaur DNA and proteins found in fossils, paleontologists claim
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.

How Do Scientists Determine the Age of Dinosaur Bones?
Date: June 18, ; Source: Field Museum; Summary: Scientists went looking for preserved collagen, the protein in bone and skin, in dinosaur fossils.
New evidence has emerged indicating that dinosaurs prowled previously unknown areas of Scotland during the Jurassic age, after a researched stumbled upon a fossil while jogging along a beach. The rare new find is the first of its kind to be uncovered on the Hebridean isle of Eigg, and anywhere outside of Skye. Researchers believe the limb bone is thought to have belonged to a stegosaurian dinosaur, like the renowned Stegosaurus. The fossil dates to the middle of the Jurassic age — the same age as fossils uncovered on Skye — and is the first dinosaur fossil to be found from the age on Eigg following finds of marine reptiles and fish documented by 19th-century geologist and writer Hugh Miller.
The bone was uncovered by Elsa Panciroli, a research affiliate at National Museums Scotland, during fieldwork funded by National Geographic Society with The Isle of Eigg Heritage Trust allowing permission for the project to be undertaken. Globally, middle Jurassic fossils are rare and until now the only dinosaur fossils found in Scotland were on the Isle of Skye. The constant action of waves has left the fossil badly damaged, but an expert team of palaeontologists were able to extract it from the rock for closer study.
Analysis of the bone, focusing on the shape and miscrostucture, has allowed experts to establish that it formed part of the hind limb of a stegosaur.

CNN Allosaurus was a fierce predator at the top of the dinosaur food chain millions of years before Tyrannosaurus rex claimed its “king of the dinosaurs” title and researchers have now discovered the earliest known species of Allosaurus.

The fossil was found in Madagascar.
Uranium technique raises dinosaur question
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.

A fossil from Classical Latin : fossilis , literally “obtained by digging”  is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons , stone imprints of animals or microbes , objects preserved in amber , hair, petrified wood , oil, coal, and DNA remnants.
The totality of fossils is known as the fossil record. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ages of rocks and the fossils they host. There are many processes that lead to fossilization, including permineralization , casts and molds, authigenic mineralization , replacement and recrystallization, adpression, carbonization , and bioimmuration.
Today’s knowledge of fossil ages comes primarily from.
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.
