My Jurassic Park: Pachycephalosaurid Domes & Teeth from Hell Creek Fm

[Troodon]

If you look at a skull, see attached, its made up of elements that are fused together.  Some of the elements are indeed pretty robust but in general it's still pretty thin especially were they come together.    Domes are the most solid portion of the skull but the elements that attaches to it are not.

How common of a find are the spike clusters vs other components of the skulls?

[Troodon]

Finding a full spike cluster is super rare and I've only seen a handful collected or for sale.   Single nodes from clusters or other parts of the skull is what is typically found and much more common .   Skull domes from more mature animals or other types of Pachycephalosaurid's is probably the next type of skull part found, rare but they are out there. 

 

Let me add that the most common skull item found are the teeth.   Most sold has Pachy are actually Thescelosaurus and can be difficult to ID.

A cool new skull element was at my doorstep today.   Love it when the mailman rings the door and presents you with a package of goodies.

Very interesting skull material thank you for sharing

Picked up a few new items at the Tucson show.  No repair on any of these specimens

Dave Evans believes this might be a new species.  Will need to get in contact with him to follow-up

Great fossils as always. Ironically, what impresses me is how consistent your photography techniques are.

Thanks on both counts

I have not photographed any of my Pachy material other that those items associated with the skull, less teeth.  Just picked up this cool tooth so its a good place start.

 

The only completely rooted Canine (Fang) tooth I've seen so it has a good home.  Have quite a few crowns some a bit larger.

Best canine tooth I've ever seen

Well Dave was correct back in 2019.  A good match for the new species just described Platytholus clemensi

Have not changed photo ID
