Where: Chubut, Argentina (44.9° S, 69.4° W: paleocoordinates 51.6° S, 46.7° W)
• coordinate stated in text
• small collection-level geographic resolution
When: Lower Member (Bajo Barreal Formation), Middle Cenomanian to Middle Cenomanian (99.6 - 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).
• bed-level stratigraphic resolution
Environment/lithology: fluvial; lenticular, graded, coarse-grained, green sandstone
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.

Katepensaurus goicoecheai n. gen. n. sp.
Katepensaurus goicoecheai n. gen. n. sp. Ibiricu et al. 2013 sauropod UNPSJB-PV 1007, associated partial skeleton: 3 anterior to middle cervical vertebrae (UNPSJB-PV 1007/1–3), 3 middle to posterior dorsal vertebrae (UNPSJB-PV 1007/4–6), & 2 caudal vertebrae (UNPSJB-PV 1007/7 & 1007/8). Newly identified holotypic material includes: fragment of R frontal (UNPSJB-PV 1007/29), indeterminate neural arch fragment & partial cervical ribs (UNPSJB-PV 1007/35–36), incomplete anterior dorsal vertebra (UNPSJB-PV 1007/13), incomplete anterior to middle dorsal vertebra (UNPSJB-PV 1007/12), incomplete anterior to middle dorsal neural arch (UNPSJB-PV 1007/31), 3 incomplete anterior caudal vertebrae (UNPSJB-PV 1007/9–11), possible metapodial fragment (UNPSJB-PV 1007/33), possible fragment of R astragalus (UNPSJB-PV 1007/32), & numerous indet. elements (UNPSJB-PV 1007/19–28,30,32 and 34). Many of these latter (e.g., UNPSJB-PV 1007/14– 16) are probably partial dorsal or anterior caudal neural spines.
