Have you ever seen a plesiosaur?
Maggy Horvath found a 100 million year ago plesiosaur in the Alberta oil sand mine. She was digging for crude oil. It has limbs looking like paddles or turtle flippers. Its a 20-metre long reptile that swam in ancient tropical seas. The plesiosaur had a mouth full of sharp, pointy teeth. Maggy Horvath must have felt surprised to discover such a rare old sea creature!
