Paraptychodus washitaensis, Medial Tooth, North TX

Albian, Cretaceous

July, 2023

 

For sure a top 3 shark tooth in my collection. The crown is in pristine condition and measures just over 15 mm across with a crown height of 10 mm! Sadly the root is chewed up unlike my lateral specimen.

The holotype tooth in NMMNH Bulletin 81 has a pretty shredded root. As I recall, yours is in much better condition. Those medial file Paraptychodus remind me a lot of Ptychodus decurrens and Ptychodus occidentalis medial teeth. The big difference is the primitive root structure and smaller size in Paraptychodus. Yours is a beauty!
