Sulphur River Skull Fragment


Tony G.

Recommended Posts

I think this is a skull fragment, but I cannot figure out from what.  Found in the North Sulphur River near Ladonia, Texas.  Found in a pile of gravel and rocks in the center of the river bed.  No other associated bones were found.  I labeled the photos Back, Front, Top, Bottom (Because thats what they look like to me).  Any help identifying it is greatly appreciated.

Nice find!!! I can tell it's bone, I just don't know what specific bone it is.

Do you have other images of additional angles?  Parts of it suggest elements from the bottom of a mosasaur skull...but not sure from these photos.

This looks like part of a brain case missing the occipital condyle. I've attached a pic of a triceratops brain case missing the same thing. Thought they sort of looked similar(ish).

Compare it to anything you can find on the basioccipital - basisphenoid for mosasaurs. 

 

Here are figures 10 and 17 from Russell's Systematics and Morphology of American Mosasaurs:
