Article
Amblyrhynchus cristatus, the marine iguana, is unique amongst the ~7000 species of living limbed lizards as it has successfully evolved adaptations that allow it to live in both terrestrial and marine environments. This species is endemic to the Galápagos Archipelago and has evolved a specialized feeding behaviour, consuming primarily the algae tha...
Article
Squamates present a unique challenge to the homology and evolution of tooth attachment tissues. Their stereotypically pleurodont teeth are fused in place by a single “bone of attachment”, with seemingly dubious homology to the three‐part tooth attachment system of mammals and crocodilians. Despite extensive debate over the interpretations of squama...

Article
The development of the iliosacral joint (ISJ) in tetrapods represented a crucial step in the evolution of terrestrial locomotion. This structure is responsible for transferring forces between the vertebral column and appendicular skeleton, thus supporting the bodyweight on land. However, most research dealing with the water‐to‐land transition and b...

A new marine lizard showing exceptional soft tissue preservation was found in Late Cretaceous deposits of the Apulian Platform (Puglia, Italy). Primitivus manduriensis gen. et sp. nov. is not only the first evidence of the presence of dolichosaurs in a southern Italian Carbonate Platform, filling a palaeogeographic gap in the Mediterranean Tethys,...
Article
Mosasaurs assigned to the genus Tylosaurus have been reported from the North Atlantic Circle Basin, including the Western Interior Seaway in North America and Europe, from the Turonian of Chihuahua, Mexico, to the early Maastrichtian of Belgium. The youngest record of Tylosaurus in North America is from the middle Campanian of the Pierre Shale, Sou...
Conference Paper
Full-text available
Based on the morphology of the sacral region, mosasauroids can be divided into: (1) plesiopelvic taxa, where a bony articulation between the pelvic girdle and sacral ribs is retained; and (2) hydropelvic taxa, where such articulation is lost. However, the question concerning the mode of the plesiopelvichydropelvic transition in mosasauroids remains...
Article
Full-text available
Mosasauroids were a successful lineage of squamate reptiles (lizards and snakes) that radiated during the Late Cretaceous (95–66 million years ago). They can be considered one of the few lineages in the evolutionary history of tetrapods to have acquired a fully aquatic lifestyle, similarly to whales, ichthyosaurs and plesiosaurs. Despite a long his...

Conference Paper
Full-text available
The analysis of secondary aquatic adaptations in different groups of amniotes was performed from a comparative and morphometric point of view, in order to define the main features that contribute to a body plan (bauplan) suitable for an aquatic lifestyle. Seventeen taxa from amongst the mesosaurs (Amniota, Mesosauridae), ichthyosaurs (Ichthyosauria...

The analysis of vertebrate material from the Salento Peninsula (Italy), currently stored at the Museum of Paleontology of the University of Rome 'Sapienza' and the Natural History Museum in Verona, led us to conduct a preliminary field survey and prospection in order to localize suitable outcrops for paleontological excavations. As a result, new st...

The illegal trade of fossils has always been a threat to the scientific relevance of specimens eventually recovered from the black market. In 2008, a huge private collection including hundreds of fossils was seized by the authorities of the Cultural Heritage in the town of Serrapetrona (Macerata, Marche, Italy). Most of the specimens were devoid of...
Article
Full-text available
The first ophthalmosaurid ichthyosaur from the Upper Jurassic deposits of the Central–Northern Apennines (Marche, Italy) is here described for the first time. The specimen is relatively complete and is referred to Gengasaurus nicosiai gen. et sp. nov. based on a unique combination of characters, including a peculiar condition of the preaxial access...
Conference Paper
Full-text available
A new specimen belonging to the family Dolichosauridae (Squamata, Pythonomorpha) was recovered in Upper Cretaceous sediments of the Apulian Platform. To date, dolichosaurs are known from the Cenomanian-Turonian deposits of southeast England, France, the US, the Middle East (Lebanon), the Balkan Peninsula (Croatia, Slovenia), and possibly Australia....

Full-text available
An extraordinarily preserved and almost complete specimen of an aquatic lizard (Squamata, Pythonomorpha), showing preservation of soft tissues (mineralized scales and muscles), was recently donated to the Museum of Paleontology of the “Sapienza” University of Rome. Unfortunately, the only information about the locality of provenance is based on an...

A collection of fossil vertebrates from the Salento Peninsula (Italy), and housed at the Natural History Museum of Verona, prompted new fieldwork in the area. The attention was focused on the northern sector of the Salento Peninsula, and led to the study of an abandoned quarry near Manduria (Taranto, Italy). The preliminary results of this investig...

The recovery of an exceptionally well preserved pythonomorph lizard from the Apulian Platform (southern Italy), together with other well-preserved and undescribed vertebrate remains in the collections of the Natural History Museum of Verona from the same deposits, led to an investigation of some interesting but so far understudied fossil localities...
Conference Paper
Full-text available
A new pythonomorph lizard gen. et sp. nov. with exceptional soft-tissues preservation was found in Upper Cretaceous marine sediments of the Apulia platform (Southern Italy). Phylogenetically related forms (‘dolichosaurs’, e. g. Pontosaurus and Adriosaurus) have been described from Upper Cretaceous deposits of the Middle East (Lebanon) and the Balka...
Conference Paper
Full-text available
With the exception of the Triassic material of Monte San Giorgio, which is quite abundant and well-preserved, the Italian fossil record about ichthyosaurs for the remainder of the Mesozoic is very poor, and usually consists of few disarticulated elements. Lower Cretaceous remains have been described from the Northern Apennines, south of Modena and...
Conference Paper
Full-text available
As the paleontology is better known and fossil trading, legal and illegal, widespread, the probability of coming up to problematic specimens increases. And more often, these fossils are not directly collected by specialists, for whom it is important to determine whether authentic or fake, but become a source of enrichment for inexperienced people w...
