Two hatchling pterosaurs with fractured arm bones point to ancient storms as the cause of mass casualties preserved in Germany’s Solnhofen Limestone.
The fast radio burst came from 130 million light-years away. That proximity allowed an in-depth search for what produced the mysterious signal.
A new analysis suggests that recent extinctions have been rare, limited mostly to islands and slowing. But others argue this is all just semantics.
Thumbnails might have boosted rodents’ food-handling skills, helping them thrive worldwide.
Four new species of aquatic birds related to modern penguins have been described from fossils found in New Zealand, showing how these creatures flourished around 60 million years ago
Researchers found that fruit fly sperm push against one another and align in orderly bundles, preventing knots that could block reproduction.
European artisans turned a Tang Dynasty tomb guardian sculpture into a symbol of medieval Venetian statehood, researchers say.
An analysis of a range of dry dog foods finds that none are nutritionally complete, but vegan and vegetarian foods compare well with meat-based ones
Flamingoes, a kingfisher and two red-crowned cranes are shown in all their glory in these images from the new book Aviary: The bird in contemporary photography
Bizarrely, Iberian harvester ant queens lay eggs that turn into male builder harvester ants, and some of her offspring are hybrids of the two species
Life teems under the Antarctic ice sheet. In subglacial Lake Mercer, it is surprisingly versatile and isolated from the rest of the world.
Cuban brown anoles have the highest blood lead levels of any vertebrate known — three times that of the previous record holder, the Nile crocodile.
On Mars, the Perseverance rover found a spotted rock that could bear signs of ancient life. On Earth, a researcher used a lookalike for a dry run.
Fossilized bones in Brazil reveal that deadly infections plagued sauropods 80 million years ago. Researchers uncovered unhealed lesions consistent with osteomyelitis, pointing to pathogens spread through stagnant waters or insect bites.

Spicomellus afer, a newly analyzed Jurassic ankylosaur from Morocco, is overturning scientists’ understanding of dinosaur evolution. Unlike any other known creature, it carried a collar of meter-long spikes fused directly to its ribs, along with an early form of tail weaponry that predates similar adaptations by over 30 million years. These bizarre features suggest its armor may have been used for show as well as protection, before shifting toward defense in later ankylosaurs.

Scientists have finally uncovered direct genetic evidence of Yersinia pestis — the bacterium behind the Plague of Justinian — in a mass grave in Jerash, Jordan. This long-sought discovery resolves a centuries-old debate, confirming that the plague that devastated the Byzantine Empire truly was caused by the same pathogen behind later outbreaks like the Black Death.
