A 2,000 kg boulder that is over a billion years old dug up from Toronto's Bloor Street

At first glance, it might look like it came from outer space, but experts say a giant rock unearthed during the construction of a downtown Toronto parkette originated right here on Earth, where it's believed to date back over a billion years. The 2,000-kilogram granite boulder turned up during the digging for a parkette in the Bloor-Annex business improvement area — and is estimated to be 1.1 to 1.4 billion years old.
