Gigantic Jurassic pterosaur fossil unearthed in Oxfordshire, UK

A team of paleontologists has discovered a fossil of a gigantic flying reptile from the Jurassic period with an estimated wingspan of more than three meters—making it one of the largest pterosaurs ever found from that era.

Fossil places extinct saber-toothed cat on Texas coast

Important scientific finds don't always come in the biggest, buzziest packages. Sometimes new discoveries come in little ugly rocks. Such is the case of a 6-centimeter-wide, nondescript mass of bone and teeth that helped ...

Musankwa sanyatiensis, a new dinosaur from Zimbabwe discovered

Fossils found on the shoreline of Lake Kariba in Zimbabwe represent a completely new dinosaur species. This remarkable find, named Musankwa sanyatiensis, marks only the fourth dinosaur species named from Zimbabwe. The research ...

'Living fossils' are unique, not ancient, say researchers

The new measure, termed "evolutionary heritage," highlights the importance of unique species traits—which include physiological adaptations, like beak variations in different birds—when assessing the richness and complexity ...
