Estancia Laguna Palacios "2005 Quarry" (Cretaceous to of Argentina)

Where: Chubut, Argentina (44.9° S, 69.4° W: paleocoordinates 51.6° S, 46.7° W)

When: Lower Member (Bajo Barreal Formation), Cenomanian to Cenomanian (100.5 - 89.8 Ma)

• Upper part of the Lower Member of the Bajo Barreal Formation (Upper Cretaceous; Fig. 2), Chubut Group. The age of the Lower Member of the Bajo Barreal Formation is widely regarded as Cenomanian–Turonian (e.g., Archangelsky et al., 1994; Bridge et al., 2000; Lamanna et al., 2002; Ibiricu et al., 2012).

Environment/lithology: fluvial; lenticular, graded, coarse-grained, green sandstone

• UNPSJBPV 1007 was recovered from the base of a 1.25-m-thick, fining upward fluvial deposit of lenticular geometry and erosive base. The specimen comes from a coarse green sandstone with numerous mudstone clasts in the matrix.

Size class: macrofossils

Collected in 2005

Collection methods: quarrying, surface (in situ), mechanical,

• UNPSJB-PV, Universidad Nacional de la Patagonia San Juan Bosco Laboratorio de Paleovertebrados, Comodoro Rivadavia, Argentina

•Other vertebrate fossils recovered from the ‘2005 Quarry’ include the partial skeletons of a turtle (M.C.L., pers. observ.) and an abelisaurid theropod dinosaur (Lamanna et al., 2011, 2012), as well as several isolated theropod teeth.
