New Species
Scientists have identified a new species of ancient animal, Tanyka amnicola, from fossils unearthed in a dry riverbed in Brazil. Dating back 275 million years, this stem tetrapod featured a highly unusual twisted jaw suggesting it ground plant material. The discovery sheds light on early Permian life in Gondwana.

Researchers have identified a new venomous pitviper species in the misty mountains of western Sichuan, China, previously mistaken for a common snake. Named Trimeresurus lii after the philosopher Laozi, the Huaxi Green Pitviper features distinct markings and eye colors between males and females. DNA analysis confirmed its unique evolutionary lineage in a global biodiversity hotspot.
Researchers have discovered a new species of wolf snake on Great Nicobar Island in India, naming it Lycodon irwini in honor of the late conservationist Steve Irwin. The glossy black, non-venomous snake measures up to one meter and faces vulnerability due to its limited habitat. The finding highlights the underexplored biodiversity of the Andaman and Nicobar region.

A tiny fossil discovered in Devon has revealed unexpected traits in one of the earliest known members of the lizard lineage. The 242-million-year-old specimen, named Agriodontosaurus helsbypetrae, lacks typical features like palatal teeth and skull hinging but boasts large blade-like teeth. Researchers from the University of Bristol used advanced scans to uncover these details, prompting a rethink of lepidosaur origins.
Researchers in China have identified a previously unknown species of mountain lizard in the upper Dadu River Valley within the Hengduan Mountains of Sichuan Province. Named Diploderma bifluviale, the lizard features a distinctive wheat-colored tongue and thrives in semi-arid shrublands at high elevations. This finding highlights the region's understudied biodiversity.
