Researchers say a newly described dinosaur from northeastern Thailand was the largest sauropod yet found in Southeast Asia, stretching about 90 feet long and weighing roughly 30 tons.

A reanalysis of 540-million-year-old Brazilian microfossils suggests structures once interpreted as traces of tiny animals were actually communities of bacteria or algae.

Fossils from Western Australian caves indicate that humans once shared Australia with at least two koala species, with a newly identified western species disappearing as forests retreated roughly 30,000 years ago.

Fossils from Gujarat point to a giant snake called Vasuki indicus that may have reached up to roughly 15 meters in length, placing it among the largest snakes ever identified

Researchers studying fossilized octopus jaws say one Cretaceous species may have reached nearly 19 meters in total length, placing it among the largest and most formidable invertebrate predators known.

A reported embryo fossil from South Africa is being described as the world’s oldest proof that therapsids, the mammal ancestors that lived between 280 and 200 million years ago, laid eggs.

A new study finds that turtles specializing in hard-shelled prey were more than five times more likely to survive the asteroid impact that wiped out the dinosaurs 66 million years ago.

A new fossil from southern China reveals that a meter-long bony fish from 425 million years ago had unique clusters of spiky teeth on soft tissue 'cushions' — a jaw design never seen before.

DNA extracted from a 12,000-year-old double burial in southern Italy has revealed that a mother and daughter both carried mutations causing a rare skeletal growth disorder. The discovery marks the earliest genetic diagnosis of its kind and offers a window into prehistoric community care.
