In a single tooth, scientists might have discovered the smallest fossil monkey as well as an important piece of primate evolutionary history. Read More >>

Ancient Bird Weighed Nearly 1,000 Pounds but Could Still Run Like an Ostrich

Palaeontologists working in Crimea have uncovered evidence of the largest bird ever found in Europe. Standing taller than an elephant and weighing nearly 1,000 pounds, this enormous bird could still run at a fast pace when threatened. Read More >>

‘Spectacular’ Opal-Laced Fossils Reveal Previously Unknown Australian Dinosaur

Palaeontologists in Australia have identified a previously unknown plant-eating dinosaur from the mid-Cretaceous. Remarkably, the fossilised bones of these creatures, which glisten in hues of blue and green, are preserved in opal. Read More >>

Incredible Fossil Shows Coordinated Swimming in a School of Extinct Fish

An exquisite fossil of photographic-like quality shows nearly 260 tiny fish swimming together in what appears to be coordinated group action. The 50-million-year-old fossil is evidence that fish have been swimming together in shoals for a very long time. Read More >>

New Breakthrough Means We Can Finally Detect the Colour Red in Ancient Fossils

Some 3 million years ago, a tiny mouse featuring reddish fur on its back and a white belly scurried across the landscape of what is now Germany. We know this thanks to a remarkable new breakthrough in which reddish colour pigment was detected in an ancient fossil—a scientific first. Read More >>

Adorable Jurassic Dinosaur May Have Flown With Bat-Like Wings

During the Jurassic period, various dinosaurs experimented with different forms of powered flight. The discovery of a new dinosaur species in China suggests some of these pioneering flyers evolved webbed fingers and an elongated forelimb, allowing them to fly in a distinctly bat-like fashion.

Gigantic T. Rex Skeleton Found in Canada is Officially World’s Biggest

Updated measurements of a large fossil found in Saskatchewan nearly 30 years ago confirm it as the world’s largest known Tyrannosaurus rex skeleton. Remarkably, the new work suggests T. rex and other dinosaurs grew to a greater size than is typically appreciated. Read More >>

Ancient Bird Fossil Includes Evidence of an Unlaid Egg

Palaeontologists in China have detected traces of an unlaid egg in a 110-million-year-old bird fossil from the Cretaceous period, in what’s considered the first discovery of its kind. And in an ironic twist, it appears the egg is what killed the mother bird. Read More >>

Cartoonishly Well-Preserved Fossil Is the Earliest Bird of Its Kind

A 52-million-year-old fossil found in Wyoming is now the earliest known seed-eating perching bird in the scientific record, a discovery that’s shedding new light on the history and early eating habits of these now-ubiquitous birds. Read More >>

Ancient Steroid Suggests Sea Sponges Were One of Earth’s First Animals

Scientists from the University of California, Riverside, are claiming to have discovered the oldest known animal fossil—an ancient sea sponge that emerged between 660 million and 635 million years ago. Read More >>

Meet the New Long-Necked Dinosaur Called ‘Giant Thunderclap at Dawn’

The discovery of a new Jurassic dinosaur in South Africa shows that the transition from small, two-legged creatures to the thunderously huge long-necked dinosaurs wasn’t a straightforward process. Read More >>

Extraordinary Evidence Suggests 558-Million-Year-Old Fossil Is the Oldest Known Animal on the Planet

An international team of researchers is claiming to have discovered traces of cholesterol on a fossil of Dickinsonia—a mysterious creature that lived during the primordial Ediacaran Period. This evidence, the researchers say, makes Dickinsonia the oldest known animal in the fossil record. But the discovery is not without its critics, who say the new work is unconvincing. Read More >>

Misidentified Fossils Could Rewrite the History of Lemurs on Madagascar   

A leading theory of recent decades is that lemurs colonised Madagascar around 50 million years ago. As they dispersed throughout the island and made homes in its tropical rainforests, those ancestral lemurs evolved into the menagerie of species we see today. It’s certainly a romantic idea, but it might also be false, according to new fossil research. Read More >>

The Asteroid That Killed The Dinosaurs Also Jumbled Shark Evolution

More than 500 different shark species roam Earth’s oceans: from zippy little cookie-cutter sharks, to the iconic great white, to nightmarish goblin sharks, to 25-foot-long, filter-feeding basking sharks. And it seems that the current equilibrium of shark species we see today arose after the Cretaceous–Paleogene mass extinction event 66 million years ago, according to new research. Read More >>

Giant Dinosaur Foot Identified 20 Years After Being Unearthed

The Black Hills mountain range in the US, which stretches from South Dakota to Wyoming, is known for its lush forests, scenic waterfalls, and dense, intricate cave systems. But 150 million years ago, humongous, long-necked dinosaurs called sauropods roamed there – and scientists just identified one of their colossal, fossilised feet. Read More >>
