AMAZING Triceratops Occipital Brain Case Skull Dinosaur Tooth Fossil Fossils
Here is a great addition to your collection! Your looking for something different! You have a rex tooth and a trike horn.
Maybe you have a small dinosaur skeleton. So what else do you need!
How about the natural endocast of a triceratops brain?
This fossil is the Occipital and partial brain case of a HUGE Triceratops horridus. The pictures do not justify the size of this piece. The Occipital is 4.5 inches in diameter.
So many amazing things about this fossil.
1. There is the natural surface where the brain lived. You can see in the picture of the Triceratops brain the triangular area that matches.
2. There is a small cretaceous sharks tooth stuck to the surface of the piece that came to rest when this piece was in loose sediment. How many cretaceous sharks teeth are associated with Dinosaurs?
3. ITS BIG
4. If you look at the side you will see 3 protruding features.
This is a natural endocast of the actual brain. Very rare and curious. When the case was more complete, natural river fine sediment filled the brain cavity. As the bone broke away it left this positive impression of some of the neural stems so you can see and touch it. This is not rock but hardened silt so it is beyond amazing that this feature did not break off in the mud.
Put all this together and you have something that has value beyond dollars.
This beautiful piece has been prepped and stabilized. The occipital has 40% restoration The tooth and endocast are all natural and as found.
