What kind of dinosaur was on Doctor Who last night?

Well the tardis did that dinosaur a bigger favor than captain Jack.

And I suppose it could be silurian genetic inhancements, or that silurians particular brand of braggadocio. Do they ever even say the dinosaur was from earth's past? In various doctor who stories dinosaurs have been taken off earth maybe it's a tyrannosaur that got to evolve on a low gravity moon eh?

Ah Captain Jack!

OK, another question, on "Dinosaurs on a Spaceship", the dinos were more or less "normal" size, yet Vastra recalls them being much larger. What gives?

Younger specimens perhaps? Makes sense to populate a new world with younger animals than old ones past their breeding prime.

They had populations on the ship, most of it including the nest was to small to fit a 70 meter tall animal in
