- Comments
- DhLh-VP2: Comment by R.E. Morlan: The sample was a left tibia of a bison with the proximal end missing. Measurements of the distal end (breadth = 7.8 cm; depth = 6.0 cm) show that this bison was almost certainly an adult male. These measurements are near the upper end of the size range for modern Plains bison bulls, and it is possible that an older chrono-subspecies such as ~B. bison occidentalis< is represented. The manner of removal of the proximal end of this bone is consistent with damage caused by large carnivorous mammals. However, no definite tooth-marks are preserved. The bone lay on the surface for a brief period (a few months?) prior to burial as shown by longitudinal cracking similar to Behrensmeyer's (1978) stage 1 weathering. While in the active layer, the bone was etched by plant roots, but the degree of etching is quite modest and the extent of etching is scattered and localized. Interruption of the etching process suggests a relatively short interval of time before deeper burial was achieved. There is no evidence of human intervention in the dismemberment or defleshing of this bison.
