Saber-toothed anchovy relatives hunted in the sea 50 million years ago

Saber-toothed anchovy relatives hunted in the sea 50 million years ago

Less pizza topping and more toothy hunter, ancient anchovy kin once had quite the bite. Fossils show that these fish were armed with a mouthful of fearsome teeth. Each of the two newly analyzed specimens sport spiky teeth along the lower jaw and one giant dagger jutting down from the top jaw. Stranger still, the…
Spinosaurus fossil tail suggests dinosaurs were swimmers after all

Spinosaurus fossil tail suggests dinosaurs were swimmers after all

Sharp-toothed Spinosaurus didn’t just stand in the shallows to snag fish for dinner; this dinosaur may have been an excellent swimmer. Spinosaurus aegyptiacus, a new fossil discovery reveals, had a paddle-shaped tail that may have helped the predator slice through the water with the grace of a crocodile. The fossilized tail, unearthed from 95-million-year-old rocks…

The ancient mammal Adalatherium hui is so weird that it eluded classification for over a decade. A roughly 70-million-year-old skeleton of the species, uncovered in Madagascar in 1999, was clearly a mammal. But it boasted several distinctly un-mammalian features, such as a large hole on top of its snout. Also, although the animal’s forelimbs were…

Crawling through tight underground passages in southern France, paleontologist Jean-David Moreau and his colleagues have to descend 500 meters below the surface to reach the only known footprints of long-necked dinosaurs called sauropods ever found in a natural cave. The team discovered the prints, left by behemoths related to Brachiosaurus, in Castelbouc Cave in December 2015…
The first frog fossil from Antarctica has been found

The first fossil of a frog found in Antarctica gives new insight into the continent’s ancient climate. Paleontologists uncovered fragments of the frog’s hip bone and skull in 40-million-year-old sediment collected from Seymour Island, near the tip of the Antarctic Peninsula. Scientists have previously found evidence of giant amphibians that walked Antarctica during the Triassic…
Two primate lineages crossed the Atlantic millions of years ago

Four fossilized molar teeth excavated in Peru’s Amazon basin come from a now-extinct lineage of primates that rafted across the Atlantic Ocean from Africa and reached the inland site between around 35 million and 32 million years ago, researchers say. Until now, South American sites had yielded only fossils of primates ancestral to those inhabiting…

A wolf-sized warrior, kin to the fierce, feathered Velociraptor, prowled what is now New Mexico about 68 million years ago. Dineobellator notohesperus was a dromaeosaur, a group of swift, agile predators that is distantly related to the much larger Tyrannosaurus rex. The discovery of this new species suggests that dromaeosaurs were still diversifying, and even…

Behold the Wonderchicken, the earliest modern bird ever found. Asteriornis maastrichtensis lived 66.7 million years ago, less than a million years before the asteroid impact that doomed all nonavian dinosaurs. The winged and beaked descendants of this quail-sized bird, however, survived that mass extinction event, forming a long lineage that includes modern chickens and ducks.…

A tiny, toothed bird that lived 99 million years ago appears to be the smallest known Mesozoic dinosaur, an era from about 252 million to 66 million years ago. The creature’s 12-millimeter-long skull was found encased in a chunk of amber originally discovered in northern Myanmar, researchers report March 11 in Nature.  Of modern birds…
A squid fossil offers a rare record of pterosaur feeding behavior

A squid fossil offers a rare record of pterosaur feeding behavior

A fossil of a squid with a pterosaur tooth embedded in it offers extraordinary evidence of a 150-million-year-old battle at sea. While many pterosaur fossils containing fish scales and bones in their stomachs have revealed that some of these flying reptiles included fish in their diet, the new find from Germany is the first proof…
