Show Us Your Dinosaur Jaws!

Show us your dinosaur jaws!

I recently got my first piece. A partial dentary of a juvenile Edmontosaurus from the Hell Creek. After scanning it with photogrammetry I also mirrored the jaw to create the right side of the jaw as well. Quite happy with how the scan turned out too.

I am sorry Lord Trilobite for I am not worthy. You see your highness, I am but a poor man who does not own any dinosaur jaws. Or teeth. Or vertabraes. Or, well you get the point. But nice specimen you have.

Doesnt work at my place

But looks great ! Sry also dont have a jaw ....

Nice jaw from a very young Edmontosaurus. Love how you mirrored the other side, gives it a interesting perspective.

Really neat jaw and scan! That's a nice addition.

This is my only jaw. It's a small, partial Baryonyx jaw with a single tooth in it.

[LordTrilobite]

Wow, aren't Baryonyx fossils really rare?

The jaw comes from Sussex in England. Any dinosaur fossils from Europe or England are hard to find unless it's a washed up chunk of bone.

Sometimes bigger is not better but all dinosaur jaws are a treasure. Here is a tiny jaw from the Hell Creek Formation of Montana that I don't belive I've posted. I believe it compares favorably (see reference source) to the theropod Richardoestesia gilmorei but not positive. At only 5cm, three unerupted teeth are clearly visible, 2 poking through the remains of the erupted teeth.

Incredible! Both the jaw and teeth are in perfect condition. Is that a self find?

No, I wish it was

I have a chunk of jawbone from a Hell Creek Edmontosaurus, but this one is from an adult. It's about 6 inches in its longest dimension.

I think Troodon should be 'banned' from posting on this topic He has so many jaw-dropping specimens...makes the rest of us poor in comparison!

I’ve just found this topic, and seen this jaw, amazing jaw!! I’ve never seen a Baryonyx jaw!!

[Runner64]

Thanks @dinosaur man unfortunately, it’s no longer in my collection but still a cool piece!

[LordTrilobite]

It's been a while. By now I have more dinosaur jaw pieces. So here are two more models.

 

Another piece of Edmontosaurus from Hell Creek. Not the most complete, but it has a number of teeth still in place.

 

Here's another piece of hadrosaur lower jaw from Aguja formation. This one is likely from Kritosaurus.

Spinosaurid jaw from the Kem Kem Beds in Morocco.

According to the finder the tooth has been found at the same dig site but not in the jaw. The tooth has later been mounted by an European re-seller to make a nice display (the tooth can be detached). The jaw is 100% sand-glue-mixture free. 

 

Left: 

Small jaw from the Kem Kem Beds in Morocco. It seems to fit spinosaurid better than crocodile.

 

Middle:

Jaw fragment from Uzbekistan, Bissekty Fm. Not sure what it is. Crocodile maybe? I will show it to a palentologist soon to get his opinion. 

Again, the tooth has not been found in the jaw.

I recently got this partial mosasaur jaw in the mail! Seller stated it is a lower jaw from the Mososaur prognathodon. 16.3cm (6 1/2") long. From Khouribga, Morocco. There are 4 teeth; however, the three large teeth are not original.

Here's a piece of a hadrosaur jaw from Drumheller Alberta. I think it's corythosaurus but not sure if it can be identified to a species level. 8 cm long
