They do have the fused nasals early on.

They do have these special little teeth at the front of the jaw very early on.

They're feathered early on.

Definitively, we have...

skeletons with feathers on them that are early tyrannosaurs uh at least until the early cretaceous um

But yeah, they're knocking around as relatively small animals in Europe and Asia.

We have a couple from the UK.

We have a whole bunch from China.

There's stuff from like Kyrgyzstan and places like this.

I think there's a relatively early one from Russia.

And then when they get into the early Cretaceous, they start getting quite a bit bigger.

So something like Eutyrannus, if you want to.

There you go.

So Eutyrannus is fuzzy.

We have three specimens definitively feathered.

Um, it gets to six, seven meters long.

There's something funny looking about the sexy smaller earlier version of the T-Rex.

But again, this is seven, eight meters, maybe weighs half a ton or a ton.

Like we are very much on the menu for an animal that size and it's massive and dangerous.

Quite what triggered them, there's general patterns in evolution of size change.
