Classical reconstruction of a Triceratops (Wikimedia Commons) Until recently, Carbon-14 dating was never used to test dinosaur bones, as the analysis is only reliable up to 55,000 years.Scientists never considered it worthwhile to run the test since it is generally believed that dinosaurs have been extinct for 65 million years, based on radiometric dating of the volcanic layers above or below fossils, a method which the Paleochronology Group states has “serious problems and gross assumptions must be made”.The new facility is the second-largest dinosaur museum in the state, dwarfed only by the Museum of the Rockies in Bozeman."We are totally different from the Museum of the Rockies in that we present fossils and all the exhibits in the context of biblical creation," said Otis E. Lafferty, Dispatch Science Reporter A Columbus creation science group says Soviet tests confirm dinosaurs and humans were contemporaries as recently as 10,000 years ago, some 66 million years after dinosaurs were supposedly eliminated in a mass extinction.

Ivanov, a researcher at Moscow State University, used a technique called laser mass spectroscopy, which measures small quantities of chemicals, to analyze samples of the bones. The press release comes out in November 1991 discussing the discoveries of "Soviet scientists". This suggests to me that someone, observing the soviet union starting to dissolve, has timed the press release so that no one can check the source. Laser Mass Spectrography is only one step in carbon dating.It is the ratio between the isotopes C-12 and C-14 that defines the age.Columbus Dispatch, The (OH) November 3, 1991 CREATIONISTS SAY DINOSAURS LIVED WITH MAN Author: Michael B.Lafferty, Dispatch Science Reporter A Columbus creation science group says Soviet tests confirm dinosaurs and humans were contemporaries as recently as 10,000 years ago, some 66 million years after dinosaurs were supposedly eliminated in a mass extinction.This is then incorporated into plants by photosynthesis, and animals acquire 14C by eating the plants.

When the animal or plant dies, it stops exchanging carbon with its environment, and from that point the amount of 14C it contains begins to reduce as the 14C undergoes radioactive decay.But a quote from Genesis clues in visitors that the 20,000-square-foot building, which opened in Glendive this summer, is not your standard natural-history museum. Later he then went on the the University of Illinois to start his studies as a National Institutes of Health postdoctoral fellow, and later he became a professor of microbiology at Mississippi State University.Instead, the museum, located in an area of Montana known for world-class dinosaur fossils, offers a literal, biblical account of creation. At MSU he taught graduate level molecular genetics courses and also was the major professor for many doctoral and masters students.The Triceratops brow horn was excavated by palaeontologist Otis Kline Jr, microscope scientist Mark Armitage, and microbiologist and avocational palaeontologist Kevin Anderson, in May 2012, and two horn samples (GDFM 12.001a and GDFM 12.001b) were given to the Glendive Dinosaur and Fossil Museum in Montana.The samples were then sent to the University of Georgia, Center for Applied Isotope Studies for Carbon-14 dating, which yielded an estimated date of 33,570 ± 120 years for the first sample and 41,010 ± 220 years for the second.In short, he has no – and apparently no intention of getting – any actual education. Indeed, he has somehow managed to become president of the Southern California Society for Microscopy and Microanalysis and a member of the American Society of Parasitologists.
