Mysterious dinosaur a swimmer? Dinosaurs are often appreciated for their size and oddity. In this regard, the North African carnivorous theropod Spinosaurus, with its huge dorsal sail and a body larger than Tyrannosaurus rex, has long stood out. This species also stands out because of its history. The unfortunate loss of the type specimen during World War II left much of what we know about Spinosaurus to be divined through speculation and reconstruction. Ibrahim et al. now describe new fossils… 

Semi-aquatic adaptations in a spinosaur from the Lower Cretaceous of Brazil

Comments on the ecology of Jurassic theropod dinosaur Ceratosaurus (Dinosauria: Theropoda) with critical reevaluation for supposed semiaquatic lifestyle

Ceratosaurus is a genus of carnivorous theropod that is characterized by distinctive horns located midline of its nasal and above of its eyes. The type species of this genus, Ceratosaurus nasicornis

Convergent Evolution of Jaws between Spinosaurid Dinosaurs and Pike Conger Eels

A suite of craniodental characters unexpectedly shared by spinosaurs and pike conger eels are reported, providing an additional convincing argument regarding the decades-long and widely debated lifestyle of spinosaurs.



A long-snouted predatory dinosaur from africa and the evolution of spinosaurids

The close phylogenetic relationship between the new African spinosaurid and Baryonyx from Europe provides evidence of dispersal across the Tethys seaway during the Early Cretaceous.

Oxygen isotope evidence for semi-aquatic habits among spinosaurid theropods

It is concluded that spinosaurs had semiaquatic lifestyles, i.e., they spent a large part of their daily time in water, like extant crocodilians or hippopotamuses, and sheds light on niche partitioning between large predatory dinosaurs.


Abstract Spinosaurid theropod dinosaurs appear to represent convergent morphological evolution toward a crocodylian-like cranial morphology, previously linked to the possibility that spinosaurs

A Basal Dinosaur from the Dawn of the Dinosaur Era in Southwestern Pangaea

A previously unidentified basal theropod is described, its contemporary Eoraptor is reassessed as a basal sauropodomorph, the faunal record of the Ischigualasto Formation is divided with biozones, and the formation is bracketed with 40Ar/39Ar ages.

Early Evolution and Higher-Level Phylogeny of Sauropod Dinosaurs

The cladistic analysis presented here focuses on higher-level relationships among sauropods, and identifies Neosauropoda as a new taxon that includes Haplocanthosaurus, Camarasaurus, and Titanosauriformes.

Predatory Dinosaurs from the Sahara and Late Cretaceous Faunal Differentiation

Late Cretaceous (Cenomanian) fossils discovered in the Kem Kem region of Morocco include large predatory dinosaurs that inhabited Africa as it drifted into geographic isolation. One, represented by a

Baryonyx, a remarkable new theropod dinosaur

The study so far suggests that the Surrey dinosaur was a typical large theropod in certain respects, resembling, for example Allosaurus, however, it differs sufficiently from all known dinosaurs to merit designation as the representative of a new species, genus and family.

The skull and neck of the basal theropod Herrerasaurus ischigualastensis

The skull of Herrerasaurus ischigualastensis has a rectangular profile and a transversely narrow snout and other features of the skull constitute dinosaurian synapomorphies, such as the loss of the postfrontal and small post-temporal opening.

Microanatomy of the amniote femur and inference of lifestyle in limbed vertebrates

The femoral microanatomy of 155 species of extant amniotes of known lifestyle is studied to demonstrate a possible link between some basic parameters of bone structure and specific lifestyles, as well as phylogenetic relationships between taxa.


Abstract An analysis of 80 thin-sections of the long bones of a relatively large and presumably adult specimen of Confuciusornis sanctus, a basal bird from the Early Cretaceous of China, reveals
