Abstract. The Early Jurassic Toarcian Oceanic Anoxic Event is considered one of the most dramatic environmental perturbations of the Mesozoic. An elevated extinction rate among marine invertebrates accompanied rapid environmental changes, but effects on large vertebrates are less understood. We examined changes in ichthyosaur body size in the Posidonia Shale of the Southwest German Basin spanning the extinction interval to assess how environmental changes and biotic crisis among prey species…

Abstract The Early Jurassic was marked by several episodes of rapid climate change and environmental perturbation. These changes culminated during the Toarcian Oceanic Anoxic Event (T-OAE), an
Refining the marine reptile turnover at the Early–Middle Jurassic transition
TLDR
A series of ichthyosaurian and plesiosaurian specimens from successive geological formations in Luxembourg and Belgium are described that detail the evolution of marine reptile assemblages across the Early–Middle Jurassic transition within a single area, the Belgo–Luxembourgian sub-basin.
Stenopterygiids from the lower Toarcian of Beaujolais and a chemostratigraphic context for ichthyosaur preservation during the Toarcian Oceanic Anoxic Event
Abstract We report new ichthyosaur material excavated in lower Toarcian levels of the LafargeHolcim Val d'Azergues quarry in Beaujolais, SE France. A partially articulated skull and a smaller,
Paleobiology of ichthyosaurs: using osteohistology to test hypotheses of growth rates and metabolism in a clade of secondarily aquatic marine tetrapods
TLDR
New material of the small-bodied Upper Triassic ichthyosaurian Toretocnemus is described from the Nehenta Formation and the Hound Island Volcanics of Southeast Alaska, shedding light on the clade's diversity before the end Triassic extinction event.
Palaeoepidemiology in extinct vertebrate populations: factors influencing skeletal health in Jurassic marine reptiles
TLDR
The results show that the incidence of pathologies is dependent on taxon, with the small-bodied genus Stenopterygius exhibiting fewer skeletal pathologies than other genera, and the quantification of the occurrence of pathology within taxa and across guilds is critical to constructing more detailed hypotheses regarding changes in the prevalence of skeletal injury and disease through Earth history.
Stomach contents of the Early Jurassic fish †Lepidotes Agassiz, 1832 (Actinopterygii, Lepisosteiformes) and their palaeoecological implications
TLDR
Two specimens of the ginglymodian fish †Lepidotes (Lepisosteiformes) from the Lower Jurassic of Germany that exhibit gastric contents consisting of small crustacean cuticle fragments indicative of shrimp-like taxa are reported.

TLDR
The study of how faunal associations co-vary with long and short term sea level and temperature changes has implications for predicting the long-term effects of “dead zones” in modern oceans.

Early Triassic Marine Biotic Recovery: The Predators' Perspective
TLDR
The data indicate that marine ecosystems characterized by multiple trophic levels existed from the earliest Early Triassic onwards, and that a major change in the taxonomic composition of predatory guilds occurred less than two million years after the end-Permian extinction event, in which a transition from fish/amphibian to fish/reptile-dominated higher troPHic levels within ecosystems became apparent.
