Researchers have discovered the first baby tyrannosaur fossils in Alberta and Montana. Experts say the fossils are a rare discovery, as little is known about young tyrannosaurs and their development, according to a study published in the Canadian Journal of Earth Sciences on Monday. The study, led by Greg Funston, was based on two fossils: a small toe claw found in Morrin, Alta., and a small, lower jawbone found in Montana. Tyrannosaurs have been well-researched but fossils from tyrannosaur eggs or embryos have never been found — until now. The claw was found after a large sediment was taken from a dig expedition in Alberta several years ago, Powers said.
