KurzfassungDie Ichthyosaurier waren die am stärksten an das Wasserleben angepaßten mesozoischen Reptilien. Die ältesten Ichthyosauier aus der oberen Untertrias (Spath) zeigen schon einen besonderen Satz von Merkmalen (sehr große Augen, verlängerte Schnauze, tief amphicoele Wirbel, zu Flossen umgebildete Beine), die mit ihrer vollaquatischen Lebensweise zusammenhängen, und sie waren vermutlich schon nicht mehr zum Landgang fähig. Die Schlüsselinovation der Ichthyosaurier war das Lebendgebären… 

Ophthalmosaurian (Ichthyosauria) records from the Aalenian–Bajocian of Patagonia (Argentina): an overview

Abstract The oldest ophthalmosaurian records worldwide have been recovered from the Aalenian–Bajocian boundary of the Neuquén Basin in Central-West Argentina (Mendoza and Neuquén provinces). Although

A new leptonectid ichthyosaur is described, Wahlisaurus massarae gen. et sp.

A review of Russian Upper Jurassic Ichthyosaurs with an intermedium/humeral contact. Reassessing Grendelius McGovan, 1976

A cladistic analysis is applied to place Grendelius and Brachypterygius as distinct groups in a phylogenetic context and gives good reason to regard the genus Otschevia Efimov, 1998 as a subjective junior synonym of Grendalius.

A longirostrine Temnodontosaurus (Ichthyosauria) with comments on Early Jurassic ichthyosaur niche partitioning and disparity

The question of whether postcrisis recovery of vertebrate faunas, including the radiation of Temnodontosaurus into a new ecological niche, may have been a consequence of marine ecosystem reorganization across this event is raised.


The aim of this note is to analyze the syntype series of M. nordenskioeldii to clarify the taxonomy of mixosaurid ichthyosaurs and find out which diagnostic characters are present in the syntypes.

Recent study of ophthalmosaurid ichthyosaurs has brought us a number of new taxa; however, the validity of several ophthalmosaurid taxa from the Volgian (Tithonian) of European Russia still remains

Platypterygius Huene, 1922 (Ichthyosauria, Ophthalmosauridae) from the Late Cretaceous of Texas, USA

A partial ichthyosaur skeleton is described from the Grayson Marl (Late Cretaceous: Early Cenomanian, ~97 Ma) from Tarrant County, Texas. Prior to this discovery, the Cretaceous record of Texas

Ichthyosaurs of the British Middle and Upper Jurassic. Part 2. Brachypterygius, Nannopterygius, Macropterygius and Taxa invalida

Abstract In Part 2, ichthyosaur taxa of the Late Jurassic are described; three taxa are considered valid: Brachypterygius extremus, Nannopterygius enthekiodon, and Macropterygius sp. indet.



New finds ofOmphalosaurus and a review of Triassic ichthyosaur paleobiogeography

KurzfassungTriassische Ichthyosaurier sind weit verbreitet und sehr vielgestaltig, aber die meisten Formen sind schlecht bekannt. Neue Funde, wie sie hier beschrieben werden, unterstreichen die erste

Mikadocephalus gracilirostris n. gen., n. sp., a new ichthyosaur from the Grenzbitumenzone (Anisian-Ladinian) of Monte San Giorgio (Switzerland)

KurzfassungEin nahezu vollständiger Schädel eines neuen Ichthyosauriers aus der mitteltriassischen Grenzbitumenzone vom Monte San Giorgio (Kanton Tessin, Schweiz) stellt einen der vollständigsten und

A revision of the Longipinnate Ichthyosaurs of the Lower Jurassic of England, with descriptions of two new species (Reptilia: Ichthyosauria)

A revision of the longipinnate ichthyosaurs of the English Lias (Lower Jurassic) estabhshes five valid species. One of these is referred to the Upper Liassic genus Stenopterygius, the others to the

A case against a diapsid origin of the Ichthyosauria

The case for the diapsid origin of ichthyosaurs made by TARSITANO (1982,1983) is revisited. The skull on which TARSITANO'S original observations and hypotheses were mainly based is rediscussed and

The description and phenetic relationships of a new Ichthyosaur genus from the Upper Jurassic of England

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 and Middle Jurassic

The phylogenetic relationships of sauropod dinosaurs

The results suggest that there are dangers inherent in the view that ‘higher’ level sauropod phylogeny can be accurately reconstructed using only a small number of well-known taxa, and that the results of the randomization tests indicate that the data-matrix probably contains a strong phylogenetic ‘signal’.

The large ichthyosaur Cymbospondylus buchseri, sp. nov., from the Middle Triassic of Monte San Giorgio (Switzerland), with a survey of the genus in Europe

ABSTRACT The anterior half of an ichthyosaur skeleton from the Middle Triassic Grenzbitumenzone Beds of Monte San Giorgio, Switzerland, is described as Cymbospondylus buchseri, sp. nov. When compared

A putative ancestor for the swordfish-like ichthyosaur Eurhinosaurus

  • Environmental Science, Geography
  • 1986
The recent discovery of a geologically older (Lower Liassic) ichthyosaur with a partially extended rostrum appears to be ancestral, and could have given rise to Eurhinosaurus through changes in growth rates of the roStrum and mandible.

A large ichthyosaur from the Early Tithonian (Late Jurassic) of the Neuquén province, Argentina, represents a new genus and species, Caypullisaurus bonapartei, within the family Ichthyosauridae. The

A remarkable small ichthyosaur from the Upper Triassic of British Columbia, representing a new genus and species

A small, nearly complete ichthyosaur skeleton is described from the Upper Triassic of Williston Lake, in northeastern British Columbia. The age of the material, based on conodonts, is early Norian.
