Article
Full-text available
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 ichthyos...

The genus Macrocnemus is a member of the Tanystropheidae, a clade of non-archosauriform archosauromorphs well known for their very characteristic, elongated cervical vertebrae. Articulated specimens are known from the Middle Triassic of Alpine Europe and China. Although multiple articulated specimens are known, description of the cranial morphology...
Article
Full-text available
Besanosaurus leptorhynchus Dal Sasso & Pinna, 1996 was described on the basis of a single fossil excavated near Besano (Italy) nearly three decades ago. Here, we re-examine its cranial osteology and assign five additional specimens to B. leptorhynchus, four of which were so far undescribed. All of the referred specimens were collected from the Midd...
Article
Full-text available
The availability of a large sample size from a range of ontogenetic stages makes Stenopterygius quadriscissus a good model to study ontogenetic variation in a fossil sauropsid. We qualitatively examined pre- and postnatal ontogenetic changes in the cranium of S. quadriscissus. The prenatal ossification sequence is similar to other diapsids, exhibit...
Article
Full-text available
Palaeontologists often use finite element analyses, in which forces propagate through objects with specific material properties, to investigate feeding biomechanics. Teeth are usually modeled with uniform properties (all bone or all enamel). In reality, most teeth are composed of pulp, dentine, andenamel. We tested how simplified teeth compare to m...
Article
Full-text available
Large vertebrate carcasses contain significant amounts of nutrients that upon death are transferred from the water column to the benthos, enriching the immediate environment. The organisms exploiting these ephemeral resources vary as the carcass decays, creating an ecological succession: mobile scavengers arrive first, followed by enrichment opport...
Conference Paper
Full-text available
Ichthyosaurs are a diverse clade of viviparous Mesozoic marine reptiles, characterized by a series of dramatic cranial adaptations for underwater pursuit predation. A handful of taxa are known from lagerstätten deposits and are represented by a wide range of ontogenetic stages, including gravid females. In order to evaluate the ontogenetic trajecto...
Conference Paper
Full-text available
Viviparity is a common adaptation for marine tetrapods to accommodate reproduction in an aquatic habitat. The Ichthyosauria acquired viviparity early in their evolutionary history, likely around the time they entered their aquatic habitat or even as an exaptation. Stenopterygius quadriscissus is an Early Jurassic ichthyosaur, well-known for the man...
Article
Full-text available
Over the past decades, an increasing number of reptiles have been described from the Middle Triassic of southern parts of China. Marine reptiles such as thalattosaurs, ichthyosaurs and sauropterygians dominated these paleofaunas and are known to have had a Tethys-wide distribution. Indeed, several species have been described from both the eastern a...
