“…A recent visit to the collections of the Indian Statistical Institute resulted in the identification of an isolated humerus that was inadvertently excluded from the forthcoming publication (Novas et al 2010). Although incomplete, the humerus exhibits a suite of abelisaurid features which provide additional anatomical information for the newly erected taxon (Novas et al 2010).…”

“…The collection includes premaxilla, cervical, dorsal, sacral, and caudal vertebrae, portions of pectoral and pelvic girdles, and several hindlimb bones. This new material, housed at the Geology Museum of the Indian Statistical Institute, Kolkata, provides comprehensive anatomical information on this new Indian abelisaurid and will be published soon, warranting a new genus and species (Novas et al 2010).…”

The Lameta Formation (Upper Cretaceous, Maastrichtian) of India has yielded abundant fossils of abelisaurid theropods, including bones from the cranium, vertebral column, pectoral and pelvic girdles, and hindlimb. However, the forelimbs of Indian abelisaurids remain unknown. Here we describe an abelisaurid humerus from exposure of the Lameta Formation near the village of Rahioli in northwestern India. This new material exhibits derived traits that are distinctive of Abelisauridae, for example an articular head that is hemispherical in proximal view, thus establishing the specimen as the first abelisaurid humerus from India.

“…Based on the relative abundance of carnivorous dinosaurs, abelisaurids were probably the most numerous theropods in the Bauru Basin as was also the case in Late Cretaceous paleoecosystems in most other parts of Gondwana (e.g. Patagonia, Madagascar, India; Bonaparte, 1991;Novas et al, 2008Novas et al, , 2010Canale et al, 2009). …”

“…Although broken, the preserved part of the centrum has a foramen that, based on its location and shape, could correspond to a pneumatic foramen. This type of pneumatic opening is also present in the axis of the abelisauroid Masiakasaurus (Carrano et al, 2002(Carrano et al, , 2011 and the abelisaurids Carnotaurus (Bonaparte et al, 1990;Méndez, 2014), Majungasaurus (O'Connor, 2007), Rahiolisaurus (Novas et al, 2010), and Compsosuchus (Novas et al, 2004) The right fi bula, MPMA 08-0069-13, is almost completely preserved ( Figure 5). The bone is 40 cm in total length, almost 10 cm in proximal width, and 5 cm in transverse length.…”

MPMA 08-0016-95 is similar to the axes of Carnotaurus, Ceratosaurus and Masiakasaurus (Carrano et al, 2011) in that the odontoid process surpasses the anterior edge of the axial intercentrum (Figure 4), whereas in Majungasaurus, Rahiolisaurus andCompsosuchus Matley &Huene, 1933 (Novas et al, 2004), the anterior edge of the axial intercentrum is reached but not exceeded by the odontoid process (Méndez, 2010).…”

-Isolated bones of abelisauroid theropods from the Bauru Group (Late Cretaceous, Brazil), are described. They correspond to three individuals represented by fused ischia and part of the ilium, a partial axis, and a right fi bula, respectively. The fossils come from different sites in the municipalities of Ibirá (axis and fi bula) and Monte Alto (ilium and ischia), São Paulo State, from Maastrichtian beds of the São José do Rio Preto and the Marília formations (Bauru Group), respectively. The specimens provide new information on abelisauroids which are still poorly known in the Brazilian fossil record, and on the distribution of this diverse group of theropod dinosaurs in South America. These discoveries indicate that abelisauroids were the most common large predatory dinosaurs in the outcrops where they come from.

We present the pelvic and hindlimb musculature of the abelisaurid Skorpiovenator bustingorryi, constituting the most comprehensive muscle reconstruction to date in ceratosaur theropods. Using extant phylogenetic bracket method, we reconstructed 39 muscles that can commonly found in extant archosaurs. Through the identification of bone correlates, we recognized thigh and hindlimb muscles including knee extensors, m. iliofibularis, m. flexor tibialis externus, mm. caudofemorales, mm. puboischiofemorales, and crus muscles important in foot extension and flexion (e.g., m. tibialis anterior, mm. gastrocnemii). Also, autopodial intrinsic muscles were reconstructed whose function involve extension (m. extensor digiti 2–4), flexion (mm. flexor digitorum brevis superficialis), interdigital adduction (m. interosseus dorsalis) and abduction (m. interosseous plantaris, m. abductor 4). Abelisaurids like Skorpiovenator show a deep pre‐ and postacetabular blade of the ilia and enlarged cnemial crests, which would have helped increasing the moment arm of muscles related to hip flexion and hindlimb extension. Also, pedal muscles related to pronation were probably present but reduced (e.g., m. pronator profundus). Despite some gross differences in the autopodial morphology in extant outgroups (e.g., crocodilian metatarsus and avian tarsometatarsus), the present study allows us to hypothesize several pedal muscles in Skorpiovenator. These muscles would not be arranged in tendinous bundles as in Neornithes, but rather the condition would be similar to that of crocodilians with several layers formed by fleshy bellies on the plantar and dorsal aspects of the metatarsus. The musculature of Skorpiovenator is key for future studies concerning abelisaurid biomechanics, including the integration of functional morphology and ichnological data.
