Etayoa bacatensis |
Etayoa is an ungulate of the family Carodniidae in the order Xenungulata that lived during the Early Eocene (~ 55 Ma) in northern South America.
Etymology[]
The genus of the type species Etayoa bacatensis was named by palaeontologist after Fernando Etayo Serna, who contributed extensively to the paleontology and stratigraphy research in Colombia.[2] The species epithet bacatensis refers to Bacatá,[3] the name in Muysccubun for the main settlement of the southern Muisca Confederation; the name of which has been used for the current Colombian capital Bogotá, founded in a different location than the original Bacatá.
Description[]
The type species fossil specimen consists of a partial mandible with teeth, found in the Bogotá Formation in the locality Ciudad Bolívar of Bogotá, Colombia.[1] The estimated size of the ungulate is the size of a dog.[4]

The finds of iguanians, including the fossil record of hoplocercines, and boine, caenophidian, and ungaliophiine snakes in the Bogotá Formation indicate a tropical forest environment, present just before the (EECO).[5] The abundant paleosols of the Bogotá Formation show an increase in chemical weathering across the Paleocene-Eocene (P-E) transition; the Paleocene–Eocene Thermal Maximum.[6]
