Ontogeny and reproductive paleobiology in the Mesozoic marine reptile clade Ichthyosauria

2023
Ichthyosaurs were viviparous marine reptiles that occupied many consumer niches in the marine ecosystems of the Mesozoic. Their viviparous reproductive strategy lends us the opportunity to study their prenatal development in great detail and lets us assess their birthing strategies.

Evolutionary Origins of Viviparity in the Reptilia. II. Serpentes, Amphisbaenia, and Ichthyosauria

Amphibia-Reptilia, 1985
AbstractSuperimposition of reproductive mode data from the literature over phylogenetic classification systems reveals that viviparity (live-bearing reproduction) has evolved on at least 35 independent occasions among the Serpentes, once in the Amphisbaenia, and once in the Ichthyosauria.

The forefin of Chensaurus chaoxianensis (Ichthyosauria) shows delayed mesopodial ossification

Journal of Paleontology, 1998
The hitherto poorly known forefin of Chensaurus chaoxianensis (Ichthyosauria) from the Lower Triassic (Spathian) is redescribed on the basis of the holotype and two new specimens. The humerus resembles that of Utatsusaurus hataii but is distinctive in having an emarginated anterior margin.

Stenopterygius (Reptilia, Ichthyosauria) in Italian museums: morphometric and palaeoecological considerations

2023
Stenopterygius is a genus of parvipelvian ichthyosaurs whose fossil remains are mostly found in Lower Jurassic strata of the Württemberg area, Germany. Large amounts of complete, exquisitely preserved specimens of Stenopterygius have been recovered from the famous locality of Holzmaden (Württemberg) and sold to museum collections throughout Europe ...

The taxonomic status of Leptopterygius Huene, 1922 (Reptilia: Ichthyosauria)

Canadian Journal of Earth Sciences, 1996
Leptopterygius Huene, 1922, was erected for Leptopterygius tenuirostris, a fairly common long-snouted ichthyosaur from the English lower Liassic. Huene also referred eight other species to Leptopterygius, but these had little in common with L. tenuirostris, or with each another. These eight species have since been rejected, synonymized, or referred to

A SECOND SPECIMEN OF PROTOICHTHYOSAURUS APPLEBYI (REPTILIA: ICHTHYOSAURIA) AND ADDITIONAL INFORMATION ON THE GENUS AND SPECIES

Paludicola, 2018
ABSTRACT─Three isolated, partial skulls from historic collections, previously identified as Ichthyosaurus communis are herein assigned to Protoichthyosaurus prostaxalis. A fourth, nearly complete skull, NHMUK R1164 is referred to Protoichthyosaurus applebyi, only the second known specimen of the species.
