Carbonemys cofrinii is an extinct giant podocnemidid turtle known from the Middle Paleocene Cerrejón Formation of the Cesar-Ranchería Basin in northeastern Colombia. The formation is dated at around 60 to 57 million years ago, starting at about five million years after the KT extinction event.[1]
Discovery
In 2005, the holotype specimen was discovered in the Cerrejón coal mine by a North Carolina State University doctoral student named Edwin Cadena. It had a shell that measured about 1.72 metres (5 ft 8 in) and estimated at 1.8 metres (5 ft 11 in) for complete carapace,[1] making it one of the world's largest turtles.[2][3]
Paleobiology
Carbonemys’ relatively massive jaws[1] indicate that it had a powerful bite. It was likely an omnivore, consuming plants and mollusks as well as smaller reptiles, which were diverse and abundant in its neotropical freshwater habitat.[4][5] Its cohabitants included other turtles like the smaller podocnemid Cerrejonemys, the giant boid (constrictor) Titanoboa, and crocodylomorphs such as the dyrosaurids Cerrejonisuchus, Acherontisuchus, and Anthracosuchus.
