.4" Fossil Crusher Fish (Ptychodus) Tooth - Kansas

This is a fascinating, .4" wide tooth from a Crusher Shark (Ptychodus mortoni) a genus of shell-crushing sharks from the Late Cretaceous period.

Paleontologists conjecture that these crusher sharks grew to be about 4-5 meters long. Given their teeth, we can assume they probably crushed and ate large shelled animals such as giant clams and ammonites.

Comes in a small acrylic display case.
