For almost five decades, a mysterious fossil discovered during the construction of Islington subway station has remained a puzzle until recent breakthroughs. Researchers from Trent University, in collaboration with the Royal Ontario Museum and the Royal Alberta Museum, have established a connection between the fossil and two deer species commonly found throughout North America.
According to Aaron Schafer, an associate professor at Trent University involved in the study, further analysis revealed that the fossil is closely linked to whitetail and mule deer but likely represents a distinct species that diverged approximately 3 million years ago. Named “Torontoceros hypogaeus” or the “horned Toronto deer from underground” by scientists, this unique fossil is estimated to be nearly 12,000 years old and offers insights into the ancient environment.
Describing the fossil’s features, Oliver Haddrath, a collections technician at the Royal Ontario Museum, noted that it appears to have been suited for a broader, more open habitat compared to the forested areas seen in recent centuries. This suggests a tundra-like landscape that influenced the evolution of this deer species.
Looking ahead, Schafer expressed the researchers’ interest in unraveling the factors that led to the species’ extinction, speculating that climate change and genetic challenges may have played significant roles. Despite the fossil being in the possession of the ROM since its discovery, advances in DNA technology have now enabled scientists to uncover previously unanswerable questions and place ancient samples into their evolutionary context.
Although the gallery housing the fossil at the ROM is currently undergoing renovations, once reopened, visitors will have the opportunity to view the remarkable “Torontoceros hypogaeus” on display, shedding light on a fascinating chapter of natural history.
