Good thing we didn't find this one first, or the band would have been called Wee-Rex...  Lightly Touch a Finger Cymbal might not have been as big a hit.

...or if they hang out in a Pteranodon nest.

Serious question: how do they determine that it's a full grown mini-T-Rex and not a juvenile T-Rex?

Little t-rex is still 20 feet long. Not sure that wouldn't be intimidating if met in the flesh.

Because -- and there is controversy here -- they've already found juvenile T-rexs. Their proportions are different. Think a small bodied, gangly looking T-rex. This is more like a regularly shaped T-rex scaled down.

So, more of a Tyrion Rex, then?

Awww...for a moment, I thought a currently living creature had been found in the Artic that looked like a minature T-Rex.

As vertebrates grow, certain skull bones fuse together. The degree of fusion of cranial elements can be used to estimate the maturity of the individual at the time of death. This is a useful tool, but not foolproof.

You can also do histological work (cutting certain bones and looking at internal growth patterns) to estimate age, but this is an ongoing area of intense research, and growth patterns in various groups of dinosaurs show significant variation.
