Marine and terrestrial animals show a mosaic of lineage extinctions and diversifications during the Jurassic-Cretaceous transition. [] Key Result Although seven plesiosaurian lineages have been hypothesised as crossing the Jurassic-Cretaceous boundary, our most parsimonious topology suggests the number was only three. The robust recovery of a novel group including most Cretaceous plesiosauroids (Xenopsaria, new clade) is instrumental in this result. Substantial plesiosaurian turnover occurred during the…

Refining the marine reptile turnover at the Early–Middle Jurassic transition

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.

Increased pliosaurid dental disparity across the Jurassic–Cretaceous transition

Pliosaurid marine reptiles played important roles in marine food chains from the Middle Jurassic to the middle Cretaceous, frequently as apex predators. The evolution of pliosaurids during the later

Environmental drivers of crocodyliform extinction across the Jurassic/Cretaceous transition

A comprehensive analysis of crocodyliform biodiversity through the Jurassic/Cretaceous (J/K) transition is presented using subsampling and phylogenetic approaches and maximum-likelihood methods to fit models of extrinsic variables to assess what mediated these patterns.

Climate-mediated diversification of turtles in the Cretaceous

This work presents the first Mesozoic chelonian taxic richness curve, subsampled to remove geological/collection biases, and demonstrates that their palaeolatitudinal distributions were climate mediated.

Sea level regulated tetrapod diversity dynamics through the Jurassic/Cretaceous interval

A rigorous subsampling approach is applied to a comprehensive tetrapod fossil occurrence data set to assess the group's macroevolutionary dynamics through the J/K transition, culminating in the extinction of several important clades and the ecological release and radiation of numerous modern tetrapOD groups.

Diversity Patterns of Late Jurassic Chondrichthyans: New Insights from a Historically Collected Hybodontiform Tooth Assemblage from Poland

Here, we provide a detailed taxonomic reassessment of a historically collected chondrichthyan dental assemblage from the lower Kimmeridgian of Czarnogłowy in north-western Poland and discuss its

Biotic and environmental dynamics through the Late Jurassic–Early Cretaceous transition: evidence for protracted faunal and ecological turnover

These patterns suggest that different extinction selectivity and ecological processes were operating between marine and terrestrial ecosystems, which were ultimately important in determining the fates of many key groups, as well as the origins of many major extant lineages.

Sea surface temperature contributes to marine crocodylomorph evolution.

Significant correlations obtained between generic diversity and estimated Tethyan SST suggest that water temperature was a driver of marine crocodylomorph diversity.

Filling the Corallian gap: new information on Late Jurassic marine reptile faunas from England

Two of the best known Mesozoic marine reptile assemblages can be found in units deposited in the Jurassic Sub-Boreal Seaway of the UK: the late Middle Jurassic Oxford Clay Formation (OCF) and Late

Peculiar macrophagous adaptations in a new Cretaceous pliosaurid

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.



Mesozoic marine tetrapod diversity: mass extinctions and temporal heterogeneity in geological megabiases affecting vertebrates

Some evidence supports an extinction event near the Jurassic/Cretaceous boundary, but the proposed end-Cenomanian extinction is probably an artefact of poor sampling, and consideration of sampling biases allows re-evaluation of proposed mass extinction events.

High Diversity, Low Disparity and Small Body Size in Plesiosaurs (Reptilia, Sauropterygia) from the Triassic–Jurassic Boundary

High rhomaleosaurid diversity immediately following the Triassic-Jurassic boundary supports the gradual model of Late Triassic extinctions, mostly predating the boundary itself.

The phylogeny of Tetanurae (Dinosauria: Theropoda)

An exhaustive examination of all basal tetanurans and all existing character data, taking advantage of recent discoveries and adding new morphological, temporal and geographic data achieved significantly improved phylogenetic resolution.

Patterns of biotic change in Middle Jurassic to Early Cretaceous Tethyan radiolaria

New Ophthalmosaurid Ichthyosaurs from the European Lower Cretaceous Demonstrate Extensive Ichthyosaur Survival across the Jurassic–Cretaceous Boundary

There is currently no evidence that ichthyosaurs were affected by the JCB extinction event, in contrast to many other marine groups.

Dinosaur diversity and the rock record

Strong statistically robust correlations demonstrate that almost all aspects of ornithischian and theropod diversity curves can be explained by geological megabiases, whereas the sauropodomorph record diverges from modelled predictions and may be a stronger contender for identifying evolutionary signals.

The skull of the giant predatory pliosaur Rhomaleosaurus cramptoni: implications for plesiosaur phylogenetics

The first phylogenetic analysis dedicated to in-group relationships of pliosaurs allows us to hypothesise a number of well-supported lineages that correlate with marine biogeography and the palaeoecology of these reptiles.


Abstract Recent fieldwork in the Tropic Shale of southern Utah has resulted in the recovery of two new specimens of the short-necked pliosaurid Brachauchenius lucasi Williston, 1903. Both specimens
