Did Megafauna and Dinosaurs Live at the Same Time?
The discovery of collagen and soft tissue in a Tyrannosaurus-rex dinosaur femur bone was recently reported in the journal Science. Its geologic location was the Hell Creek Formation in the State of Montana, United States of America. When it was learned in 2005 that Triceratops and Hadrosaur femur bones in excellent condition were discovered by the Glendive (MT) Dinosaur & Fossil Museum, permission was asked and received to saw them in half and collect samples for radiocarbon (RC) testing of any bone collagen that might be extracted. Indeed both bones contained collagen and conventional dates of 30,890 +/- 380 for the Triceratops and 23,170 +/-170 for the Hadrosaur were obtained using an Accelerated Mass Spectrometer. Total organic carbon and bio-apatite were then extracted and pretreated to remove potential contaminants and concordant radiocarbon dates were obtained, all of which were similar to radiocarbon dates for megafauna. A study of radiocarbon literature for dating of both megaf
