Dinosaur remains from the Lower Cretaceous of the Chubut Group, Argentina
Cretaceous Research, 2003Abstract Some fragmentary dinosaur remains from the uppermost Hauterivian–Barremian La Paloma Member of the Cerro Barcino Formation of northern Chubut, Argentina are described. Together with the fauna from the La Amarga Formation of Neuquen, Argentina, this material represent the oldest known Cretaceous dinosaur fauna from South America.

Hydrography and Circulation of the Chubut River Estuary (Argentina)
Estuaries, 1989The hydrography and circulation of the Chubut River were investigated under exceptionally low river discharge. The frontal zone formed by the entrance of the tide in the estuary may be observed as far as 4.5 km from the mouth, showing that the salt intrusion due to tidal effects reaches further inland than during normal river discharge.

Massive corals in Paleocene siliciclastic sediments of Chubut (Argentina)
Facies, 2005A horizon with large, massive corals in growth position was discovered in the Paleocene, probably upper Danian, part of the Maastrichtian–Paleocene Lefipan Formation of Chubut (Patagonia, Argentina). All corals belong to one species, the cosmopolitan Haimesiastraea conferta Vaughan, which survived the end-Cretaceous mass extinction.

Early Jurassic protobranch bivalves from Chubut, Argentina
Journal of Paleontology, 2019AbstractKnowledge on Early Jurassic marine fossil invertebrates from Argentina is very uneven. Particularly, faunas from Chubut Province received less attention and were thought to be poorer than those from the Neuquén Basin. Nevertheless, an updated revision of bivalves shows that some groups, such as the Protobranchia, were relatively more diverse in
