Arroyo Picún Leufú (Jurassic of Argentina)

Also known as Herbstosaurus type

Where: Neuquén, Argentina (39.2° S, 70.1° W: paleocoordinates 37.3° S, 32.1° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Vaca Muerta Formation, Tithonian (152.1 - 145.0 Ma)

• "Originally, the holotype was cited as from the Middle Jurassic (Callovian) levels of the Lotena Formation (Casamiquela 1975)...However, in the same nodule with the pterosaur was found the ammonite Berriasiella sp., which undoubtedly belongs to the upper levels of the Tithonian, in the Vaca Muerta Formation, which is also exposed in this area."

• bed-level stratigraphic resolution

Environment/lithology: coastal; poorly lithified sandstone

• "Nearshore marine"
• "sandy arkose" quite close to where block was found

Size class: macrofossils
