Priosphenodon is an extinct Rhynchocephalian known from the Late Cretaceous of Argentina.[1] It is believed to have been a fairly large herbivore, having a longer snout than modern tuatara, with teeth specialised for shearing plant matter.[1] In fact, a recent study found several structural similarities to mammal teeth.[2] Two species are known, P. avelesi and P. minimus.[3]
Fossils of the genus have been found in the Candeleros and Cerro Barcino Formations in Argentina.[citation needed]
