This article is about the fossil site in Colombia. For the archeological site in Mexico, see La Venta.

La Venta is a settlement between the modern Tolima Department and Huila Department, Colombia. Nearby, one of the richest Neogene fossil assemblages in the whole of South America is known. It provides a glimpse of how life in the region was like before the main wave of the Great American Interchange.

Fossil site[edit]

Most glyptodonts – like this one – have been found in Patagonia, but they lived at La Venta too.

The fossils occur in Middle Miocene rocks of the Villavieja Formation and La Victoria Formation. The La Venta fauna contained ancient species of animal genera and families still alive today, as well as some entirely extinct prehistoric lineages. These animals lived some 13.8 to 12 million years ago in the Laventan age, which was named after La Venta. At that time, the climate of the region was wetter than today and there was much forest of trees similar (and probably related) to the sapino (Goupia glabra) of our time.
