Wow 3 ft. long still seems huge to me! Laying those eggs must have hurt!

*Baby tyrannosaurs were only the size of a Border Collie dog when they took
their first steps, a team of palaeontologists has discovered.*

Researchers from Edinburgh University examined fossilised remains of a tiny
jaw bone and claw found in Canada and the US.

They have been revealed, in 3D scans, to belong to a baby tyrannosaur -
cousin of the T-Rex dinosaur.

They are the first-known fossils of tyrannosaur embryos.

It suggests the creatures which lived more than 70 million years ago were
only about 3ft (91cm) long when they hatched, despite being able to grow to
40ft (12.2m) in length and weighing about eight tonnes.
