Fossil content
editThe formation has provided the following fossils:[1]
- Geochelone sp.[2]
- Eremotherium cf. laurillardi
- Notiomastodon platensis (described as Haplomastodon waringii)[3]
- 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.[4]
