Rio Aguaytia (= Podocnemis bassleri type locality) (Miocene of Peru)

Where: Peru (8.2° S, 75.3° W: paleocoordinates 8.5° S, 73.5° W)

• coordinate stated in text

When: Contamana Group, Late/Upper Miocene (11.6 - 5.3 Ma)

Environment/lithology: terrestrial; gray sandstone

• It was obtained in "a gray arkosic sandstone and conglomerate with lime carbonate nodules belonging to the Transition Beds" of the Contamana group.

Size class: macrofossils

Collected by H. Bassler in 1937; reposited in the AMNH

• This skull was donated to the Museum by the late Harvey Bassler in 1937, one of the many fruits of his explorations of eastern Peru. The skull was prepared in 1937 by Jeremiah Walsh. Further preparation was done in 1940 by John Germann, and photographs then were made. The skull was to have been described by its discoverer, but after the latter's death in 1951 the project of describing the fossil was turned over to Llewellyn I. Price during his Guggenheim visit to this country, and a preliminary description with sketches and investigations into the geology of its occurrence were then made by him. After the return of Mr. Price to Brazil, however, the pressure of other work and his own great distance from the specimen so delayed publication that he in turn gave over the task to the present author, generously surrendering the notes and sketches already made.
