}} Dracaena colombiana is an extinct species of caiman lizards from northern South America. Fossils of Dracaena colombiana have been found in the Honda Group of Colombia. The species was described as a member of the tegus; Tupinambis huilensis by Estes in 1961. DescriptionDracaena colombiana[1] was first described as Tupinambis huilensis by Estes in 1961, later named Paradracaena 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]Distribution{{see also|Honda Group, Colombia#Fossil content}}Apart from the type locality in the Honda Group, fossils attributed to the genus Paradracaena were recovered from the Pebas and Solimões Formations of the Amazon Basin of respectively Peru and Brazil.[5][6] See also{{portal|Colombia|Neogene|Paleontology|Reptiles|Prehistory of South America}}
