Environmental changes governed the diversity of marine ecosystems and the evolution of
marine reptiles during the Jurassic. Abrupt climatic changes, mainly cooling, produced …

Crocodylomorphs constitute a clade of archosaurs that have thrived since the Mesozoic until
today and have survived numerous major biological crises. Contrary to historic belief, their …

The use of more than one nomenclatural code is becoming increasingly common in some
biological sub-disciplines. To minimize nomenclatural instability, we have decided to …

Thalattosuchian crocodylomorphs were a ubiquitous component of shallow marine
ecosystems during the Jurassic and Early Cretaceous. Alas, their origins remain a mystery …

Crocodylomorphs have colonized various environments from fully terrestrial to fully aquatic,
making it an important clade among archosaurs. A remarkable example of the rich past …

Metriorhynchids are marine crocodylomorphs found across Jurassic and Lower Cretaceous
deposits of Europe and Central and South America. Despite being one of the oldest fossil …

Thalattosuchian crocodylomorphs were a diverse clade that lived from the Early Jurassic to
the Early Cretaceous. The subclade Metriorhynchoidea underwent a remarkable transition …

The cliffs and foreshore at Lyme Regis on the Dorset coast expose a sequence of Early
Jurassic marine limestones and mudstones of the Blue Lias Formation and the overlying …

During major evolutionary transitions, groups develop radically new body plans and radiate
into new habitats. A classic example is cetaceans which evolved from terrestrial ancestors to …

We describe a protocol for estimating evolutionary rates from phylogenetic trees based on
parsimony character optimization. The rate estimation is conducted through a TNT script and …
