The evolutionary history of the mock viper, a mildly venomous, widely distributed Asian snake that mimics highly venomous vipers for self-defense, has been solved. The mock viper represents a ...

The newly described Mirasaura grauvogeli from the Middle Triassic had a striking feather-like crest, hinting that complex skin appendages arose far earlier than previously believed. Its bird-like ...

WASHINGTON — Scientists in Australia have identified the oldest known fossil footprints of a reptilelike animal, dated to around 350 million years ago. The discovery suggests that after the first ...

"I'm stunned." says Per Ahlberg of Uppsala University, who coordinated the study; "A single track-bearing slab, which one person can lift, calls into question everything we thought we knew about when ...

WASHINGTON (AP) — Scientists in Australia have identified the oldest known fossil footprints of a reptile-like animal, dated to around 350 million years ago. The discovery suggests that after the ...

Fossilized footprints discovered in southeastern Australia, dating back approximately 355 million years, have forced scientists to rethink the timeline of reptile evolution. Detailed in a recent study ...

Ichthyosaurs represent a diverse clade of Mesozoic marine reptiles that rapidly adapted to fully aquatic lifestyles following the end-Permian mass extinction. Their streamlined, 'fish-like' body plan, ...

A diverse group of lizards known as the social skinks is helping scientists answer questions about some of the fundamental workings of evolution. Skinks are a large group of lizards that typically ...

Viviparity, the live-bearing mode of reproduction, has evolved independently in several vertebrate lineages, including squamate reptiles and seahorses. In reptiles, evolutionary transitions from ...

A fossil found over two decades ago on England’s Jurassic Coast has proved to be one of the most significant discoveries of marine reptiles in recent times. The almost complete skeleton of a ...

Mock vipers not only look like tree-dwelling vipers but also act like them. Intriguingly, they have a fake ‘fang’ in the front of their mouth, which befools a predator into thinking that they possess ...
