Fernando Etayo Serna is a Colombian paleontologist and geologist. His contributions on the paleontology in Colombia has been mainly on the descriptions of ammonites and Etayo has helped describing many fossiliferous geologic formations of Colombia. Etayo obtained his MSc. degree in geology and geophysics from the Universidad Nacional de Colombia in 1963, and his PhD in paleontology from the University of California, Berkeley in 1975.^[1]

Biography

In 1962, Etayo Serna published his first work about the species Codakia orbicularis and Codakia orbiculata.^[2]^[3] He has defined many geologic formations of Colombia in the 1960s and 1970s.

Etayo, together with fellow paleontologist María Páramo, collaborated in describing the first dinosaur fossil found in Colombia, Padillasaurus from the Paja Formation, close to Villa de Leyva, Boyacá.^[4]^[5] His work has been focused on the descriptions of the various ammonites found in the same formation.^[6] He also co-authored the 2016 publication about Stenorhynchosaurus munozi, found in the same formation.^[7]

Etayo has published in Spanish and English.^[8] In 1975, the year Etayo received his PhD degree, he was awarded the Louderbach Memorial Award in Stratigraphy from the University of California, Berkeley.^[1]

The ungulate Etayoa bacatensis, found in the Late Paleocene to Early Eocene Bogotá Formation south of Bogotá, has been named in honour of Etayo.^[9]
