Description
A modern relative, the northern caiman lizard (Dracaena guianensis)

Paradracaena colombiana[1] was first described as Tupinambis huilensis by Estes in 1961, later named Dracaena colombiana by Sullivan and Estes in 1997.[2] These ground dwelling insectivore-carnivores were described from fossils found in fluvial and lacustrine clays of the Middle Miocene (Laventan in the SALMA classification) Villavieja Formation in Colombia.[3] They share a number of features with extant caiman lizards, such as large teeth and a robust quadrate, but also bear more primitive characteristics, such as a higher tooth count.[4]
