For almost five decades, a mysterious fossil discovered during the construction of Islington subway station has remained enigmatic, until now. A recent study conducted by Trent University, in collaboration with the Royal Ontario Museum and the Royal Alberta Museum, has established a connection between the fossil and two deer species prevalent in North America.
According to Aaron Schafer, an associate professor at Trent University involved in the research, further analysis revealed that the fossil is closely related to whitetail and mule deer but likely represents a distinct species that diverged approximately 3 million years ago. Dubbed “Torontoceros hypogaeus” or the “horned Toronto deer from underground” by scientists, the fossil is estimated to be nearly 12,000 years old, offering insights into the ancient environment.
Oliver Haddrath, a collections technician at the Royal Ontario Museum, noted that the deer’s physical characteristics suggest it was adapted to a wider, more open landscape compared to the forested areas of recent centuries. The habitat was likely more tundra-like, shaping the evolution of this unique deer species.
Looking ahead, Schafer expressed the researchers’ interest in unraveling the factors that led to the extinction of this species. Climate changes and genetic issues due to a potentially small population are believed to have played a role in its demise.
Despite being in the possession of the Royal Ontario Museum since its discovery, the fossil’s origin remained a challenge until recent technological advancements. The introduction of a DNA lab has enabled researchers to address previously unanswerable questions and place ancient samples within their genetic lineage, as highlighted by Haddrath.
Although the gallery showcasing the fossil at the Royal Ontario Museum is presently undergoing renovations, once reopened, the “Torontoceros hypogaeus” will be available for public viewing, shedding light on this intriguing archaeological find.
