List Of Fossiliferous Stratigraphic Units Of 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.

Proposed reclassification of South American gomphotheres

Some authors, Lucas, Mothé, Avilla et al., propose a reclassification of the South American gomphotheres as follows:Lucas, 2013Mothé et al., 2012Mothé et al., 2016aMothé et al., 2016b
* ''Stegomastodon'' is an exclusively North American genus
* ''Haplomastodon'' 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 platensis''
* ''Cuvieronius'' is the only remaining South American genus outside of ''Notiomastodon''

Evolution

* Lucas (2010, 2013) proposes that ''Notiomastodon'' evolved from ''Cuvieronius'' inside South America
* Mothé et al. (2012, 2015, 2016) propose that ''Notiomastodon'' and ''Cuvieronius'' reached South America in two separate migration wavesMothé & Avilla, 2015, p.33
