Cretaceous Ichthyosaurs: Dwindling Diversity, or the Empire Strikes Back?
Geosciences, 2012 Recent descriptions of new taxa and recognition of survivorship of Jurassic genera across the Jurassic–Cretaceous boundary bring the total number of Cretaceous ichthyosaur genera to eight. Taxa currently known from the Cretaceous include Ophthalmosaurus,

New ophthalmosaurid ichthyosaurs from the European Lower Cretaceous demonstrate extensive ichthyosaur survival across the Jurassic-Cretaceous boundary. [PDF]
PLoS ONE, 2012 BackgroundIchthyosauria is a diverse clade of marine amniotes that spanned most of the Mesozoic. Until recently, most authors interpreted the fossil record as showing that three major extinction events affected this group during its history: one during ...

Papers in Palaeontology, Volume 11, Issue 5, September/October 2025.Abstract Ichthyosaurian faunas before and after the Pliensbachian stage of the Early Jurassic are known from numerous, often complete fossils. The two faunas are very different taxonomically, with only one of the pre‐Pliensbachian genera, but none of the species, persisting into the post‐Pliensbachian (Toarcian).

Papers in Palaeontology, Volume 11, Issue 3, May/June 2025.Abstract Fossilized food items found in or passed through the digestive tract of an animal (bromalites) offer a window into the dietary habits and ecological role of the producer taxon. Bromalites have been documented from several small to mid‐sized parvipelvian ichthyosaurian species from the Lower Jurassic, but are seldom documented for the largest ...

A longirostrine Temnodontosaurus (Ichthyosauria) with comments on Early Jurassic ichthyosaur niche partitioning and disparity [PDF]
Palaeontology, 2012 Abstract: We describe an almost complete ichthyosaur skeleton from the middle Toarcian (Lower Jurassic) of the Beaujolais foothills near Lyon, France, and assign it to Temnodontosaurus azerguensis sp. nov. This new species exhibits cranial peculiarities such as a thin, elongated and possibly edentulous rostrum, as well as a reduced quadrate.

A new Eurhinosaurus (Ichthyosauria) species from the Lower Jurassic (Toarcian) of Mistelgau (Bavaria, Southern Germany) [PDF]
Fossil RecordEurhinosaurus is a European Lower Jurassic longirostrine ichthyosaur, characterized by its remarkable overbite. Despite the long history of the genus, the taxonomy of Eurhinosaurus is still under debate, and its morphology is poorly understood.

Ontogeny of the braincase inStenopterygius(Reptilia, Ichthyosauria) from the Lower Jurassic of Germany [PDF]
Journal of Vertebrate Paleontology, 2019 The fossil record of the ichthyosaur genus Stenopterygius comprises a large number of specimens of all ontogenetic stages. This makes the taxon a good model for ontogenetic studies in a Mesozoic marine reptile. Here, we describe the morphology of the braincase elements of Stenopterygius over ontogeny and compare it with that of other known ichthyosaur ...

An Upper Jurassic ichthyosaur (Ichthyosauria: Ophthalmosauridae) from the Bowser Basin, British Columbia [PDF]
Canadian Journal of Earth Sciences, 2016 Although the Jurassic was a period of high diversity in ichthyosaurs, only a small number of specimens have been recorded from Canada to date. We describe here a new occurrence of an ophthalmosaurid ichthyosaur from a shallow marine depositional environment within the Bowser Basin of northern British Columbia. Based on vertebral diameters and the size
