We know Peterborough was incorporated as a city in 1905 (she’s looking pretty good at 115), and we think that if we asked most Ontarians to point to where Peterborough would be on a map, they could tentatively point somewhere between Ottawa and Toronto.
If we were to ask you where the physical location of Peterborough 400 million years ago (hint… it was under water) or even 750 million years ago, you might not know where to look.
Check out the cool site The Dinosaur Database that has a slick animated map to help you find out how the very spot that we are standing on changes over time. Our planet has sure changed through history!
