New record of snakes from the Cretaceous of Patagonia (Argentina)

Abstract

New remains of snakes from the Late Cretaceous (La Colonia Formation; Campanian-Maastrichtian) of Argentina increase the record of the earliest Patagonian snakes. They include the southernmost record of the madtsoiid snake Alamitophis, another probable madtsoiid, perhaps a boid, and a snake incertae sedis.
