Patagonia has yielded the most comprehensive fossil record of Cretaceous theropods from
Gondwana, consisting of 31 nominal species belonging to singleton taxa and six families …

Tetanuran theropods represent the majority of Mesozoic predatory dinosaur diversity and
the lineage leading to extant Aves. Thus their history is relevant to understanding the …

The Cretaceous terrestrial strata of the Neuquén Basin (northern Patagonia, Argentina) are
described together with their tetrapod records. Six local tetrapod assemblages are identified …

Recent fieldwork in the Upper Cretaceous (Maastrichtian) Maevarano Formation, northwest
Madagascar, has yielded important new skull material of the abelisaurid theropod …

Recent discoveries and analyses have drawn increased attention to Ceratosauria, a
taxonomically and morphologically diverse group of basal theropods. By the time of its first …

Abelisauroid predators have been recorded almost exclusively from South America, India
and Madagascar, a distribution thought to document persistent land connections exclusive …

Theropods have traditionally been assumed to have lost manual digits from the lateral side
inward, which differs from the bilateral reduction pattern seen in other tetrapod groups. This …

In this paper, we present an updated revision of fossil vertebrates from the Chubut Group,
