Ultraviolet light uncovers the first known juveniles of a mysterious Jurassic fish family
For more than 150 years, fossils of Jurassic fish scattered across Europe's museums were studied and drawn by generations of scientists. However, when a paleontologist decided to shine an ultraviolet light on them, a hidden world lit up.
Remarkable fossils rewrite the story of how animals conquered the land
Palaeontologists have found new evidence that the early ancestors of amphibians, reptiles and mammals did not have a larval stage with external gills like modern frogs or salamanders
A worm that lived half a billion years ago preferred turning right
Fossils of Spriggina floundersi provide the earliest evidence of animals favouring one side of the body over the other – a feature of nervous systems that we see in our own right- and left-handedness

T. rex took 40 years to reach full size, scientists find
Tyrannosaurus rex may have been a much slower grower than scientists realized. A new study of 17 tyrannosaur fossils found that the giant predator likely took about 40 years to reach its full size of roughly eight tons, extending previous estimates by 15 years.
Scientists open a million-year-old time capsule hidden beneath New Zealand
A cave in New Zealand has yielded fossils from a lost ecosystem that existed about 1 million years ago, including a possible flying ancestor of the kākāpō. The discovery reveals that volcanoes and climate upheaval were reshaping the country’s wildlife and driving extinctions long
Oldest example of preserved tube feet reveals clues about the lives of 452-million-year-ol
Echinoderms, such as starfish, sea urchins and sea lilies, use small, flexible, tubular projections called "tube feet" for locomotion, feeding, respiration and sensory perception. Crinoids, a subgroup of echinoderms, are known to have a long fossil record, but these fossils usual
Ancient proteins hint at all-female Homo naledi burial site in Rising Star cave system
Scientists have extracted and analyzed the first-ever ancient proteins from the fossils of Homo naledi, revealing a potential all-female burial site. The study, published in the journal Cell, raises the possibility that South Africa's famous Rising Star Cave system could represen
Fossils upend catastrophist narrative that flowering plants flourished only after dinosaur
A unique cache of plant fossils from volcanic deposits in New Mexico contradicts the common narrative that flowering plants were minor players in Earth's forests until dinosaurs disappeared 66 million years ago.
Beetle-like borings in 70-million-year-old titanosaur fossils reshape Lo Hueco fossil stor
Traces or perforations caused by living organisms after an animal's death can be found on various dinosaur bone remains. These perforations, known as bioerosion structures, provide information that helps us understand relationships between living organisms in the past, reconstruc
Newly identified fossil sheds light on evolutionary history of saber-toothed cats
Fossils tucked away in a museum drawer and identified merely as "feline" are actually from a very ancient and enigmatic saber-toothed cat that inhabited North America more than 5 million years ago. Newly identified by a UC Berkeley paleontologist, the nearly complete skull helps
