East Slope, Sierra Pampa de Agnía (Jurassic to of Argentina)

Also known as Cañadón Puelman

Where: Chubut, Argentina (44.0° S, 69.5° W: paleocoordinates 41.8° S, 28.5° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Cerro Carnerero Formation, Late/Upper Toarcian to Late/Upper Toarcian (180.1 - 171.6 Ma)

• fossiliferous beds rest on Liassic beds with Harpoceras subplanatum, and below the Middle-Upper Jurassic Porphyritic Series. Called the "Cerro Carnerero" beds, which "include the Bajocian in their base and may extend into the Callovian". More recently (Rauhut 2003) assigned to late Toarcian-early Aalenian interval.

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; sandy tuff and gray, blue claystone

• The remains were discovered in a bed of sandy tuff and bluish gray clay, which form part of a continental sedimentary series mixed with porphyritic conglomerates with partly encrusted round pebbles, and bluish gray cineritic clays with sandy intercalations and clays in lesser amounts.
