Cetotherium is an extinct genus of baleen whales from the family Cetotheriidae.
La Venta is a fossil locality located in the modern departments of Tolima and Huila in Colombia. This site is one of the richest Neogene fossil assemblages in South America and represents the best-known Cenozoic fossil site outside of Argentina. It provides a glimpse of what life in the region was like before the main wave of the Great American Interchange.
Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 1991.

Kronokotherium is an extinct herbivorous marine mammal of the family Desmostylidae in the order Desmostylia.
Metacarcinus is a genus of crabs formerly included in the genus Cancer. It includes nine exclusively fossil species and five extant species, of which four are also known from the fossil record. The monophyly of this genus was not supported by a molecular study using the cytochrome oxidase I gene.
Matutidae is a family of crabs, sometimes called moon crabs, adapted for swimming or digging. They differ from the swimming crabs of the family Portunidae in that all five pairs of legs are flattened, rather than just the last pair, as in Portunidae. Crabs in the Matutidae are aggressive predators.
Hepatella is a genus of crabs in the family Aethridae, containing these species:
Uruguaytherium is an extinct genus of astrapotherid mammal from the Late Oligocene to Early Miocene of South America. It was named by the Argentinean paleontologist Lucas Kraglievich in 1928, from a fragmentary fossil found in the Fray Bentos Formation of the department of Río Negro in Uruguay, and the type species is U. beaulieui. The related genera Xenastrapotherium and Granastrapotherium, which make up Uruguaytheriinae with Uruguaytherium, are also from South America, although them colonizated the equatorial zone. The holotype specimen of Uruguaytherium is a partial mandible (the left mandibular ramus), with a preserved third molar, or M3.
This list, 2014 in molluscan paleontology, is a list of new taxa of ammonites and other fossil cephalopods, as well as fossil gastropods, bivalves and other molluscs that have been described during the year 2014.
Vampalus is a genus of cetotheriid mysticete from Miocene (Tortonian) marine deposits in the Russian Caucasus. The type species, V. sayasanicus, is based on PIN 5341/1, a complete skeleton. The cetotheriid Eucetotherium helmersonii was mistakenly assigned to Vampalus by Tarasenko and Lopatin, who were unaware that Kellogg (1931) fixed "Cetotherium" helmersonii as the Eucetotherium type species.
Zygiocetus is an extinct genus of cetotheriid mysticete in the subfamily Cetotheriinae. The type and only species is Zygiocetus nartorum, known from the Late Miocene (Messinian) of Adygea in the Russian Caucasus.
