What did Hill suggest accounted for the comparative abundance of bison limb bones relative to other bison bones at the Agate Basin site?
a. Bison long bones contain little in the way of meat and marrow, making them undesirable for transport back to camp.
b. Bison are large animals that would be extremely difficult to carry whole; long bones would be preferentially transported because of their high-utility (meat and marrow).
c. Carnivore activity resulted in the natural accumulation of limb bones at the site; limbs are the easiest part of the skeleton for carnivores to remove.
d. The limb bones were the only bones to remain after carnivores scavenged the rest of the axial and appendicular skeletons.
e. The archeologists overlooked most bison bones that were broken, thus excluding all except the limb bones that were relatively intact.
Question 2
If you have a site dominated by bones from the axial skeleton, you have
a. a kill site.
b. a camp site.
c. mostly upper and lower leg bones, scapulae, clavicles, pelves, metapodials, and phalanges.
d. mostly cranial bones, mandibles, vertebrae, ribs, sacrum, and tail bones.
e. mostly all the parts of the animal.
