Overview
Fossil evidence discovered near Drumheller has presented a prehistoric 'cold case' involving an Albertosaurus carcass. Analysis of bite marks on the fossil suggests two primary, yet divergent, possibilities regarding the post-mortem interactions. These scenarios include a small raptor scavenging on an apex predator, or a juvenile Albertosaurus engaging in cannibalism.
Research Context
The discovery focuses on an Albertosaurus, an apex predator of its time. The location of the find is near Drumheller. The presence of specific bite marks on the fossilized remains forms the central evidence for the investigation into what transpired after the animal's death.
Findings
The fossilized Albertosaurus specimen exhibits bite marks. The characteristics of these bite marks are consistent with two distinct interpretations of post-mortem activity. One interpretation suggests that a small raptor fed on the remains of the Albertosaurus. The second interpretation posits that a baby Albertosaurus was involved in an act of cannibalism on the deceased individual. These two potential explanations are presented as the primary deductions from the observed fossil evidence.
Why This Matters
The analysis of these fossil bite marks provides insight into potential feeding behaviors and ecological interactions among prehistoric animals, specifically involving an apex predator. The discovery near Drumheller offers a glimpse into post-mortem processes and predator-prey or intra-species interactions that are preserved in the fossil record.
