  author={Federico L. Agnolin and Pablo Chiarelli},
  journal={Pal{\"a}ontologische Zeitschrift},
In this note we reassess the position of putative pedal phalanges of some South American noasaurid theropods (Abelisauroidea). Noasaurids were considered as to be distinctive abelisauroids with a peculiar “sickle claw” on the second toe of the foot, convergently developed with that of deinonychosaurians. Among noasaurids, the Argentinean species Noasaurus leali (latest Cretaceous) and Ligabueino andesi (Early Cretaceous) are known from incomplete specimens, including dissarticulated non-ungueal… Expand
A hypertrophied ungual phalanx from the lower Barremian of Spain: Implications for the diversity and palaeoecology of Spinosauridae (Theropoda) in Iberia
Abstract An enlarged theropod manual ungual (CSC1-4) from the Weald facies of Spain is described. The claw was found in the fossil locality of Cana Seca 1, Teruel province, within the El CastellarExpand
A New Specimen of Velocisaurus unicus (Theropoda, Abelisauroidea) from the Paso Córdoba Locality (Santonian), Río Negro, Argentina
The new material shows that Velocisaurus is remarkable in having a very short, stout, and anteriorly bowed femur, which indicates that this taxon belongs to a still poorly understood radiation of gracile-limbed abelisauroids. Expand
New abelisaurid remains from the Anacleto Formation (Upper Cretaceous), Patagonia, Argentina
Abstract New theropod remains with abelisaurid affinities from the Upper Cretaceous (Anacleto Formation, lower Campanian), NW Patagonia, Argentina, are here described. The specimen (MPCN-PV 69)Expand
First elaphrosaurine theropod dinosaur (Ceratosauria: Noasauridae) from Australia — A cervical vertebra from the Early Cretaceous of Victoria
Abstract Elaphrosaurinae is an enigmatic clade of gracile ceratosaurian theropod dinosaurs known from the Late Jurassic of Africa (Elaphrosaurus bambergi) and Asia (e.g., Limusaurus inextricabilis),Expand
Comments on “Ornithocheirus hilsensis” Koken, 1883 – One of the earliest dinosaur discoveries in Germany
Based on a detailed morphological comparison of the original figures, the lost holotype of “Ornithocheirus hilsensis” is identified as the distal part of the proximal pedal phalanx from digit I of aExpand
A new desert-dwelling dinosaur (Theropoda, Noasaurinae) from the Cretaceous of south Brazil
The recovered skeletal parts show that the new dinosaur was just over 1 m long, with a unique anatomy among theropods, and a phylogenetic analysis nests the new taxon within the Noasaurinae clade, which is unresolved because of the multiple alternative positions that Noasaurus leali can acquire in the optimal trees.

Evolution of the carnivorous dinosaurs during the Cretaceous: The evidence from Patagonia
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: Abelisauridae,Expand
The theropod dinosaur Elaphrosaurus bambergi Janensch, 1920, from the Late Jurassic of Tendaguru, Tanzania
Elaphrosaurus is placed within a dichotomous Noasauridae as part of a Jurassic subclade, here termed Elaphrosaurinae, that otherwise includes taxa from eastern Asia and underscores the long and complex evolutionary history of abelisauroids, which is still only beginning to be understood. Expand
Ceratosaur palaeobiology: new insights on evolution and ecology of the southern rulers
The results presented here suggest that abelisaurids had different soft tissues on the skull which might have been associated with evolution of a strong cervicocephalic complex and should have allowed derived taxa to have low-displacement headbutting matches. Expand
An Articulated Pectoral Girdle and Forelimb of the Abelisaurid Theropod Majungasaurus crenatissimus from the Late Cretaceous of Madagascar
ABSTRACT Abelisaurid theropods are common members of Cretaceous Gondwanan faunas and are characterized by a bizarre, highly reduced forelimb. Unfortunately, forelimb elements are rarely preservedExpand


Abstract We describe the osteology of the new small theropod dinosaur Masiakasaurus knopfleri, from the Late Cretaceous Maevarano Formation of northwestern Madagascar. Approximately 40% of theExpand
These materials illustrate that the appendicular skeleton of abelisaurids was specialized over the typical condition in basal theropods, particularly through the development of enlarged muscle attachment processes. Expand
A New Abelisaurid (Dinosauria, Theropoda) from the Lameta Formation (Cretaceous, Maastrichtian) of India
Many isolated dinosaur bones and teeth have been recovered from Cretaceous rocks in India, but associated remains are exceedingly rare. We report on the discovery of associated cranial andExpand
The Gondwanian theropod families Abelisauridae and Noasauridae
The theropod families Abelisauridae and Noasauridae appear closely related because of shared derived characters such as the short anterior area of the maxilla, the small or absent preantorbitalExpand
A large Cretaceous theropod from Patagonia, Argentina, and the evolution of carcharodontosaurids
It is suggested that carcharodontosaurid radiated in Gondwana sharing with spinosaurids the role of top-predators until their extinction in Cenomanian–Turonian times, and offers a better understanding of the evolution of Southern theropod faunas. Expand
The Phylogeny of Ceratosauria (Dinosauria: Theropoda)
A new cladistic analysis of Ceratosauria from the Late Jurassic‐Late Cretaceous of North and South America, Europe, Africa, India and Madagascar suggests that Elaphrosaurus and its relatives are the most basal ceratosaurs, followed by Ceratosaurus and Noasauridae + Abelisauridae (= Abelisauroidea).
