The Tablazo Formation is a Middle Pleistocene geologic formation of Santa Elena Province in western Ecuador. The claystones and sandstones were deposited in an estuarine environment.
Fossil content The formation has provided the following fossils:
Geochelone sp. Eremotherium cf. laurillardi Notiomastodon platensis (described as Haplomastodon waringii) Smilodon fatalis An association of two subadult and one adult specimen of Smilodon fatalis was reported from the formation by Reynolds, Seymour & Evans (2021), who interpret the subadult specimens as likely to be siblings, and evaluate the implications of this finding for the knowledge of the life history of S. fatalis.
