The Acasta gneiss is the oldest known exposed rock on Earth. According to Wikipedia, the rock body is exposed on an island about 300 kilometres north of Yellowknife, Northwest Territories, Canada. The rock of the outcrop was metamorphosed 3.58 to 4.031 billion years ago and is the oldest known intact crustal fragment on Earth.[1]

This next model is someone else entirely. The front of its top jaw comes down in a point, and the front of its bottom jaw comes up in two points which surround the top-jaw point. The model of scaphonyx is about 15" long.
Pterodactyl.
Closer look. That bone around (in?) the eye......
Ok-to-touch cast of the skeleton of a teeny tiny pterosaur.
Ok-to-touch life-size model of an allosaurus head. I should have touched this one, too, so you could see how big it is....
