The colonisation of freshwater and marine ecosystems by land vertebrates has repeatedly
occurred in amphibians, reptiles, birds and mammals over the course of 300 million years …

All living jawed vertebrates possess teeth or did so ancestrally. Integumental surface also
includes the cornea. Conversely, no other anatomical feature differentiates the clades so …

While every jawed vertebrate, or its recent ancestor, possesses teeth, skin appendages are
characteristic of the living clades: skin denticles (odontodes) in chondrichthyans, dermal …

ABSTRACT A new genus and two new species of mosasaurs are described from five
specimens collected during quarrying operations in the 'Lastame'lithotype located in the …

Mosasaurs are secondarily aquatic squamates that became the dominant marine reptiles in
the Late Cretaceous about 98–66 million years ago. Although early members of the group …

The dolphin-like ichthyosaurs–also known as 'fish lizards'–are extinct marine reptiles that
roamed the Mesozoic oceans for some 160 million years. As for most ancient vertebrates …

Metriorhynchidae are the only archosaurs that show adaptations to a highly pelagic lifestyle.
This morphology is paralleled by ichthyosaurs and plesiosaurs, which share a streamlined …

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 …

In Volume 2 of The Vertebrate Integument the emphasis is on the structure and functional
design of the integument (including its derivatives) and contribution to locomotion in …

Adaptations of mosasaurs to the aquatic realm have been extensively studied from the
perspective of modifications to the post‐cranial skeleton. In recent years, imaging …
