Inspection of the femur cross section in Fig.3b revealed dried up Haversian systems and very little apparent mineralization.
Samples from different interior locations were easily removed by hand with a with a stainless steel scoop-type instrument as shown in Fig.3c and placed in plastic bags for further study.
It is very slippery in wet, and crunchy in dry condition, according to paleontologist Otis Kline.
Triceratops and Hadrosaur locations: The exact location for the Triceratops femur is 47 degrees 6 minutes & 18 seconds North by 104 degrees, 39 minutes & 22 seconds West. The highest nearby point is approximately 201 m southwest of the find and is 669 m above sea level.
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.
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).
Six fragments from a single diamond exhibited essentially identical C-14 values – 69.3 ± 0.5 ka – 70.6 ± 0.5 ka BP as reported by Taylor and Southon.
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).
In light of the discovery of soft tissue in a T-Rex from the Montana Hell Creek Formation and RC dates for other fossils in the geological record it was decided to examine the bone interior of this femur, as Libby's team did with Smilodon and Schweitzer et al. 2a to 2d shows the support system including Plaster of Paris and wooden support base.
