For close to five decades, a perplexing fossil discovered during the construction of Islington subway station has kept its secrets hidden — until now. Researchers from Trent University, in collaboration with the Royal Ontario Museum and the Royal Alberta Museum, have uncovered 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 study, further analysis revealed that the fossil is most closely related to whitetail and mule deer. However, it is likely a distinct species that diverged approximately 3 million years ago. This fossil, named Torontoceros hypogaeus or the “horned Toronto deer from underground,” is estimated to be nearly 12,000 years old and is considered a unique specimen shedding light on ancient life.
Describing the fossil’s habitat, Oliver Haddrath, a collections technician at the Royal Ontario Museum, remarked that it appears to have been suited for a broader, more open environment compared to the forested landscapes of recent centuries. The surroundings would have been more tundra-like, influencing the physical characteristics of this deer.
Looking ahead, Schafer expressed the researchers’ interest in delving deeper into the reasons behind the species’ extinction. Climate factors are known to have played a role, with Schafer suggesting that a combination of genetic issues and environmental challenges might have hindered the species’ adaptation.
The Royal Ontario Museum had possessed the fossil since its discovery, but technological limitations had hindered the identification process. With advancements in DNA analysis, the museum can now unravel mysteries surrounding ancient specimens and their evolutionary history.
Although the gallery housing the fossil is currently undergoing renovations at the Royal Ontario Museum, once it reopens, visitors will have the opportunity to marvel at Torontoceros hypogaeus on display, offering a glimpse into the ancient past.
