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).Abstract: The discovery of collagen 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.Perhaps the most informative documentation of Figs.1 and 2 is that they show the sequence of excavating a 122 cm long Triceratops femur from discovery, to pedestal, to plaster, to separation. Photos 3a-3c are of Triceratops femur bone during and after sawing; photo 3d is a portion of Glendive MT Dinosaur and Fossil Museum field research station; photomacrograph 3e is of material from bone interior containing bone collagen.
summarized these extensive mammoth RC dating studies but collagen content was not discussed. reported on C-14 dating of small mammoths on Wrangell Island in the Arctic Ocean north of Siberia: The eight mammoth bones, tusks and teeth gave RC ages at 4000 to 5000 RC years BP using purified collagen. Three dacite components from the final lava flow of A. Furthermore, fossil materials other than dinosaur bones and amber that should be free of C-14 but contain significant amounts include anthracite coal, fossil natural gas, fossil wood and marble resulting from the metamorphism of limestone.
The Hadrosaur location was in a dry wash which flows into Frank Creek, then into Glendive Creek and then into the Yellowstone River just North of Glendive Montana in the NW ¼, NE ¼ of Sec.
32, T16N, R56 E, Dawson County, Montana about 13 km south-east of the Triceratops location according to Otis Kline (2). 1 and Fig 2 were taken during excavation for the Triceratops femur.
It can also be seen from Fig.1a that the femur was located very close to the surface.
Because of its proximity to the surface, the paleontologists had to contend with some roots of living plant material before reaching the bone.
