Puesto Hernández, PH 1297 [MAU] (Cretaceous to of Argentina)

Also known as Rincón de los Sauces

Where: Neuquén, Argentina (37.4° S, 69.1° W: paleocoordinates 42.2° S, 49.4° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Plottier Formation (Neuquén Group), Late/Upper Coniacian to Late/Upper Coniacian (89.3 - 83.5 Ma)

• middle-upper part of formation

• bed-level stratigraphic resolution

Environment/lithology: alluvial fan; paleosol/pedogenic, concretionary, brown, red, calcareous, cherty/siliceous conglomerate and yellow sandstone

• fluvial system of sandy-gravel channel interfaces, deposited in a dense fluid ("fangoso")
• "an alternation of yellowish quartzite sandstones and solid fangolites of red color...the fossiliferous level belongs to a level of red-brown fangolites approximately 3 m thick, characterized by the presence of an elevated content of heterometric detrital grains of sand and microconglomerate size, of natural silica and carbonate. The detritals are encountered irregularly distributed, observed in addition to the presence of carbonate nodules of possible pedogenic origin and small cylindrical galleries of transported invertebrates, which are not encountered 'in situ'." Deposit associated with "plant strings".
