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.[https://paleobiodb.org/classic/displayCollResults?collection_no=67633 Tablazo Formation] at Fossilworks.org
Fossil content
The formation has provided the following fossils:
- Geochelone sp.Cadena et al., 2017
- Eremotherium cf. laurillardi
- Notiomastodon platensis (described as Haplomastodon waringii)Cantalamessa et al., 2001
- 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.Reynolds et al., 2021
