The dinosaur fossil record from Mexico is sparsely documented since most of it is fragmentary remains with little taxonomic information and a lot of it conti...

We reconstruct the major cranial musculature of the giant stem amphibian Mastodonsaurus giganteus, revealing a differentiated jaw-adductor system, a probable sesamoid pulley, and previously unrecogni....

Top predators drive changes in ecosystem structure. For the last ~370 million years, large-sized vertebrates have dominated the apex of the marine food chain, while invertebrates have served as smalle...

Temnodontosaurus, a large ichthyosaur from the Early Jurassic, was one of the first ichthyosaurs to be scientifically described as early as the 19th century. Over time, various large Toarcian ichthyos...

The Pseudosuchia (Diapsida, Archosauria) arose during the Early Triassic and were the dominant large to medium-sized tetrapods in continental ecosystems until the Triassic–Jurassic extinction. Despit...

The updated European Red List of Freshwater Fishes – the most comprehensive assessment in 15 years – reveals little evidence of species recovery and calls for urgent action to protect Europe’s aquatic...

Thalattosuchians, an extinct lineage of Mesozoic crocodylomorphs, underwent a remarkable evolutionary transition from primarily semi-aquatic teleosaurids, through increasingly ocean-adapted metrior...

We describe teleosaurid remains from the Middle to Upper Jurassic Khlong Min Formation at Ban Nam Pun in southern Thailand and define Indosinosuchus peninsularensis sp. nov. This new species is diagnosed by a unique combination of cranial and postcranial features, including the nasal reaching anteriorly at the level of the 18th maxillary alveolus, absence of an incisive foramen, oval-shaped external nares, and broad ornamented osteoderms. Phylogenetic analysis positions I. peninsularensis within a polytomy alongside Mystriosaurus laurillardi and other Asian teleosaurids, supporting a monophyletic Teleosauroidea. In addition, the revision of Indosinosuchus kalasinensis as a junior synonym of I. potamosiamensis also strengthens the taxonomic framework of the genus Indosinosuchus. Indosinosuchus peninsularensis sp. nov., discovered in a low-energy lagoonal environment, offers significant insights on the ecological preferences of teleosaurids. In contrast to the fluvially deposited Phu Kradung Formation of northeastern Thailand, the lagoonal and marginal marine sediments of the Khlong Min Formation are considered indicative of a broad spectrum of habitat occupation by Asian teleosauroids. Based on these observations, a high degree of ecological plasticity has been inferred for Thai teleosaurids, and their extensive dispersal across both the Sibumasu and Indochina terranes during the Middle to Late Jurassic has been further substantiated. The recognition of I. peninsularensis sp. nov. contributes to our understanding of teleosaurid diversity and paleobiogeography in Southeast Asia.

Why do we love what is rare and despise what is all around us?

New evidence suggests that diffusive oxygen transport through the tracheolar–muscle system is not the limiting factor on insect body size.

Conservation efforts have traditionally been focused on saving the rarest, most threatened species, and for good reason. But what if our singular focus on endangered species is causing us to overlo…

By combining GPS tracking from 244 individuals across 22 herds in Europe, Retez et al. demonstrated that the European bison is a generalist species, with scale- and season-dependent habitat use. Thei...
