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.
Fig.3a shows the Triceratops femur dissection using carefully cleaned saw with the bone supported by wood frame and plaster of Paris cast.
Possibly the RC dated femur bone belongs to the Triceratops remnants from "Lone Ridge." Thus testing for C-14 in other bones seems to be the next step in the ongoing research.
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.
Materials and Methods Geology of the Montana Badlands: Most of the strata are the brownish-grey sediments of the Hell Creek formation thought to date back 65 million years (when the Rocky Mountains were rising in the West and there was much volcanic activity).
At that time, much of the region was part of river-plains similar to the present southeastern United States with sub-tropical climate and vegetation of the Cretaceous period or the Age of Reptiles.
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, 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.
Total organic carbon and/or dinosaur bone bio-apatite was then extracted and pretreated to remove potential contaminants and concordant radiocarbon dates were obtained, all of which were similar to radiocarbon dates for megafauna. Walter Libby's team of collagen from "dense mid-shaft femur bones" of twelve extinct saber tooth tigers, [Smilodon] from the Le Brea Tar Pits of Los Angeles CA.
It contains much volcanic material such as bentonite, or clays such as montmorillonite or vermiculite.
It is very slippery in wet, and crunchy in dry condition, according to paleontologist Otis Kline.
did with the T-Rex "hind limbs." The Triceratops femur bone was discovered in what is called "popcorn clay." Since the bone was so huge (122 cm long and 20 cm through the shaft area) and completely intact [hard, and neither crushed nor deformed, ideal for extracting possible bone collagen] it was sawed open in late July 2005 near the proximal end, as shown in Fig. The Triceratops femur was resting on a layer of popcorn clay in an apparent, almost aseptic sand and fine clay matrix.
It can also be seen from Fig.1a that the femur was located very close to the surface.
