Carbonemys cofrinii is an extinct podocnemidid turtle known from the Middle Paleocene Cerrejón Formation of northeastern Colombia. The formation is dated at around 60 to 58 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), making it one of the world's largest turtles.[2][3]

The jaws of Carbonemys were massive and would be powerful enough to eat crocodylians, that were abundant in the first neotropical forest of the Cerrejón Formation.[4] This turtle coexisted with the giant boid, Titanoboa.
