Anisomyon cf. cassidarius, Arcadia Park

Anisomyon cf. cassidarius, Denton Co.

Turonian, Cretaceous

Jan, 2023

Anisomyon are limpet-like gastropods found throughout Cretaceous strata. They are conic in shape and have a characteristic single ridge running from the center to the edge of the shell. These gastropods are known from the uppermost Arcadia Park, but little research has been dedicated to them. Anisomyon cassidarius has been reported from the Lower Turonian to Santonian and shares some visual similarities with my specimen. Surprisingly, this is not my first example of Anisomyon; I have a larger one from the NSR!
