List of fossiliferous stratigraphic units in Colombia
Several stratigraphic units in Colombia have provided fossils. The richest formations are the Devonian Cuche and Floresta Formations, the Cretaceous Paja Formation, the Paleocene Cerrejón Formation and the Miocene La Venta site. The latter is the richest Konzentrat-Lagerstätte in northern South America and comprises the formations of the Honda Group.
Fossiliferous stratigraphic units
''Formations are ordered according to their youngest age''Proposed reclassification of South American gomphotheres
Some authors, Lucas, Mothé, Avilla et al., propose a reclassification of the South American gomphotheres as follows:Stegomastodon is an exclusively North American genusHaplomastodon is a South American genus, but synonymous with Notiomastodon- as Notiomastodon was defined earlier, all Haplomastodon species should be considered part of Notiomastodon
- all formerly described species as Stegomastodon sp., Haplomastodon sp. and Notiomastodon sp. belong to a single species; Notiomastodon platensisCuvieronius is the only remaining South American genus outside of ''Notiomastodon''
Evolution
- Lucas proposes that Notiomastodon evolved from Cuvieronius inside South America
- Mothé et al. propose that Notiomastodon and Cuvieronius reached South America in two separate migration waves
