    FIRST RECORD OF ICHTHYOSAURS IN SICILY(UPPER TRIASSIC OF MONTE SCALPELLO, CATANIA PROVINCE) by CRISTIANO DAL SASSO, GIANNI INSACCO, ALFIO ALESSANDRO CHIARENZA, DAVIDE DI FRANCO, AGATINO REITANO

    Published 2014-03-01
    “…Here we report for the first time on the presence of ichthyosaurs in Sicily, southern Italy. The deposit of origin (Mufara Formation) can be dated to the upper Carnian (Tuvalian substage) based on a typical association of ammonites, one of which (Shastites sp.) is embedded in the sediment still encrusting one of the bone specimens recently found. …”

    Heads or tails first? Evolution of fetal orientation in ichthyosaurs, with a scrutiny of the prevailing hypothesis by Feiko Miedema, Nicole Klein, Daniel G. Blackburn, P. Martin Sander, Erin E. Maxwell, Eva M. Griebeler, Torsten M. Scheyer

    Published 2023-04-01
    “…Here, we draw upon published and original evidence to test two hypotheses: (1) Ichthyosaurs inherited viviparity from a terrestrial ancestor. (2) Asphyxiation risk is the main reason aquatic amniotes give birth tail-first. …”

    A new specimen of Palvennia hoybergeti: implications for cranial and pectoral girdle anatomy in ophthalmosaurid ichthyosaurs by Lene Liebe Delsett, Patrick Scott Druckenmiller, Aubrey Jane Roberts, Jørn Harald Hurum

    Published 2018-10-01
    “…The Late Jurassic Slottsmøya Member Lagerstätte on Spitsbergen preserves a diverse array of marine reptiles, including four named taxa of ophthalmosaurid ichthyosaurs. One of these, Palvennia hoybergeti, is based on the single holotype specimen (SVB 1451) with an incomplete skull. …”

    A large new Middle Jurassic ichthyosaur shows the importance of body size evolution in the origin of the Ophthalmosauria by Feiko Miedema, Dylan Bastiaans, Torsten M. Scheyer, Christian Klug, Erin E. Maxwell

    Published 2024-03-01
    “…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 ichthyosaurs, many early parvipelvian taxa went extinct. …”

    Oldest record of Machimosaurini (Thalattosuchia, Teleosauroidea): teeth and scavenging traces from the Middle Jurassic (Bajocian) of Switzerland by Torsten M. Scheyer, Michela M. Johnson, Dylan Bastiaans, Feiko Miedema, Erin E. Maxwell, Christian Klug

    Published 2024-04-01
    “…Here, we document the first evidence of macrophagous/durophagous Machimosaurini-tribe teleosauroid thalattosuchians from the late Bajocian (ca 169 Ma) in the form of three robust tooth crowns with conical blunt shapes and anastomosed pattern of thick enamel ridges towards the apex, associated with the skeleton of a large ichthyosaur lacking preserved tooth crowns. The tooth crowns were found on the posterior section of the lower jaw (left angular), a lacrimal and the axis neural arch of the ichthyosaur. …”
