Where: Chile (52.1° S, 70.0° W: paleocoordinates 52.7° S, 64.2° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Palomares Formation, Santacrucian (17.5 - 16.3 Ma)

• "The geology of the Fell cave is illustrated by Bird (1988, p. 136, Fig. 48), who shows that the roof of the cave is formed by a volcanic conglomerate, the sides for stratified sandstones, and the floor for bentonite clay. Nevertheless, the observations of the authors of this work suggest that bentonite clay and sandstones stratified represent the Palomares Formation in Chile (Santa Cruz Formation in Argentina, see below). Therefore, the remains of glyptodon reported by Emperaire (1988) they would come from bentonite clays of the Palomares Formation, which have below of the last archaeological level. Another argument that supports this Suggestion is that Gliptodontes are very common in the Santa Cruz Formation of southern Argentina (just north of the Chilean border, see Scott, 1903), and have not been registered in Pleistocene deposits in the southern part of Argentina and Magallanes, Chile. Therefore, the Fell Cave archaeological site would be 18-15 Myr younger than the fossil glyptodon and its Stratigraphic proximity consists only of a coincidence.
