Dating the age of dinosaurs

Dinosaurs supposedly died out 65 million years ago. Carbon-14 dating was recently performed on dinosaur fossils,1 and the results were presented at the Western Geophysics Meeting in Singapore, August 2012, a gathering of approximately two thousand scientists.1 The carbon-14 dating involved precautions against contamination.

The data was challenged by Thomas Stafford as poor science due to assumed contamination from modern C-14 with younger surficial calcium carbonate.Footprints, flowers, even droppings; all of these things can be turned into fossils under the right conditions.A fossil only becomes a fossil when it has reached a certain age.Accelerated Mass Spectrometer (AMS) dating of dinosaur bone bio-apatite from 170 grams of bone fragments and milligram surface scrapings of an Acrocanthosaurus dinosaur gave ages of 25,750 ± 280 and 23,760 ± 270 respectively.No collagen was detected and only bone bio-apatite was RC dated.When it was learned in 2005 that Triceratops and Hadrosaur femur bones in excellent condition were discovered by the Glendive (MT) Dinosaur & Fossil Museum, Hugh Miller asked and received permission to saw them in half and collect samples for C-14 testing of any bone collagen that might be extracted.

Indeed both bones contained collagen and conventional dates of 30,890 ± 380 radiocarbon years (RC) for the Triceratops and 23,170 ±170 RC years for the Hadrosaur were obtained using the Accelerated Mass Spectrometer (AMS).

Types of Fossils There are two main types of fossils: body fossils and trace fossils.

A body fossil is the physical remains of an animal. Some very small organisms, called microbacteria, leave behind microscopic particles called filaments.

A Triceratops brow horn discovered in Dawson County, Montana, has been controversially dated to around 33,500 years, challenging the view that dinosaurs died out around 65 million years ago.

The finding radically suggests that early humans may have once walked the earth with the fearsome reptiles thousands of years ago.
