Polyacrodus aff. brevicostatus, Lower Glen Rose


Polyacrodus aff. brevicostatus, Canyon Lake

Albian, Cretaceous

Jan, 2024


I believe it is likely P. brevicostatus instead of P. parvidens because it is low crowned, has more than 2 pairs of lateral cusplets, and has labial nodes present on all cusps/cusplets. I'll admit it's hard to be super confident in an ID as most papers are pretty old/inaccessible.
