Bite marks on a baby bison pelvis?
According to Research Associate Chris Shaw, these marks were made by a carnivore. There are two clearly defined depressed fractures on the anterior medial (inner) surface of this ilium (part of the pelvis) and one on the lateral (outer) surface, suggesting that this animal was bitten by a carnivore hard enough for their teeth to puncture the bone. These sorts of paleo-pathologies are not very common at Rancho La Brea and this is the first evidence of possible bite marks identified from Project 23. In Box 1, excavators have found the remains of several baby bison. This individual (catalog number P23-10498) was very young when it became mired in the asphalt.
