Computational simulations of potential Pachycrocuta bite damage based on a ~1.2 Ma ravaged hippopotamus femur from Fuente Nueva 3 (Orce, Granada, Spain)

Q: What does this research mean for the field?

The extinct giant hyena Pachycrocuta brevirostris produced remarkably large, deep, and circular tooth pits on dense cortical bone, the size and morphology of which can serve as a diagnostic reference for identifying its activity in the fossil record. Novelty: ClaimNovelty.NOVEL_FINDING. Consensus alignment: ConsensusAlignment.NEUTRAL.

Key Points

To characterize the tooth pit morphology and feeding damage of the extinct giant hyena Pachycrocuta brevirostris using computational modeling on a damaged Early Pleistocene hippopotamus femur.
Digitized carnivoran tooth marks from a ~1.2 Ma hippopotamus femur from Fuente Nueva 3 using three-dimensional microscopic techniques.
Applied artificial intelligence algorithms to simulate the morphological bite variability and damage patterns of Pachycrocuta brevirostris.
Simulations demonstrated that Pachycrocuta brevirostris produced distinctively large, deep, and circular tooth pits on dense cortical bone.
Generated a diagnostic reference framework to distinguish giant hyena bone modification patterns in the prehistoric fossil record.
