Even after 200 years of study, some details of the cranial anatomy of ichthyosaurs, one of the
most successful groups of marine vertebrates in the Mesozoic, are still unclear. New …

Cretaceous ichthyosaurs have typically been considered a small, homogeneous
assemblage sharing a common Late Jurassic ancestor. Their low diversity and disparity …

Cretaceous ichthyosaurs were relatively diverse in temperate latitudes, but few species have
been described from the palaeotropics. Here, we describe a new ophthalmosaurid …

A large and previously unknown ichthyosaur is reported from the Kimmeridge Clay (Upper
Jurassic) of Stowbridge, Norfolk, England. The only valid genera described from the Upper …

Most ichthyosaurs from the English Lower Jurassic are dolphin-sized, with skull lengths of
about 500 mm and body lengths of up to 2,500 mm. Very large ichthyosaurs are rare, and …

Abstract The Middle Jurassic is an important time period for the evolutionary history of
marine reptiles as it represented a transitional phase for many clades. Notably, in …

Chaohusaurus is one of the earliest-branching ichthyosauriforms, but its cranial anatomy
remains poorly known due to the lack of well-preserved material. Here, three nearly …

In the last decade, several new Cretaceous ichthyosaurs have been described and/or
redescribed, challenging the traditional concept that, during the Cretaceous, ichthyosaurs …

Abstract Besanosaurus leptorhynchus Dal Sasso & Pinna, 1996 was originally described on
the basis of a single complete fossil specimen excavated near Besano (Italy). However, a …

Ichthyosaurians (Ichthyosauria) are a major clade of secondarily aquatic marine tetrapods
