A New Barremian (Early Cretaceous) Ichthyosaur from Western Russia
ABSTRACT A new ophthalmosaurid ichthyosaur, Sveltonectes insolitus, gen. et sp. nov., is described from a sub-complete and three-dimensionally preserved specimen from the late Barremian of western
New Ophthalmosaurid Ichthyosaurs from the European Lower Cretaceous Demonstrate Extensive Ichthyosaur Survival across the Jurassic–Cretaceous Boundary
TLDR
There is currently no evidence that ichthyosaurs were affected by the JCB extinction event, in contrast to many other marine groups.
Extinction of fish-shaped marine reptiles associated with reduced evolutionary rates and global environmental volatility
TLDR
It is shown that ichthyosaurs maintained high but diminishing richness and disparity throughout the Early Cretaceous, and that global environmental change resulted in a major, temporally staggered turnover event that profoundly reorganized marine ecosystems during the Cenomanian.
A basal thunnosaurian from Iraq reveals disparate phylogenetic origins for Cretaceous ichthyosaurs
TLDR
The first post-Triassic ichthyosaur from the Middle East is described, Malawania anachronus gen. et sp.
High Diversity in Cretaceous Ichthyosaurs from Europe Prior to Their Extinction
TLDR
The taxonomic diversity of late Albian ichthyosaurs now matches that of older, well-known intervals such as the Toarcian or the Tithonian, suggesting strong geographical disparities in the diversity pattern of Albian–early Cenomanian ICHthyosaurs.
A new Lower Cretaceous ichthyosaur from Russia reveals skull shape conservatism within Ophthalmosaurinae
TLDR
The skull of a new basal ophthalmosaurine ichthyosaur, Leninia stellans gen. et sp.
Plasticity and Convergence in the Evolution of Short-Necked Plesiosaurs
Peculiar macrophagous adaptations in a new Cretaceous pliosaurid
TLDR
It is indicated that Early Cretaceous marine reptile teeth with serrated carinae cannot be unequivocally assigned to metriorhynchoid crocodylomorphs and the known diversity of dental adaptations seen in Sauropterygia, the longest lived clade of marine tetrapods are extended.
Simbirskiasaurus and Pervushovisaurus reassessed: implications for the taxonomy and cranial osteology of Cretaceous platypterygiine ichthyosaurs
TLDR
The cranial anatomy and phylogenetic relationships of these taxa illuminate the evolution of narial aperture anatomy in Cretaceous ichthyosaurs, clarify the phylogenetic re- lationships among platypterygiines, and provide further arguments for a thorough revision of Platypterygius.
