Although an extinct animal was from a different group of marine mammals, an examination of fossils showed it evolved a way of eating that was very similar to that of [...]

You've heard of a ''frog in your throat,'' but probably not like this. On a hike through a sweaty Peruvian jungle in 2016, Kim Roelants, a biologist at Vrije University [...]

El superpegamento natural, formado por unas inusuales proteínas, protege a las ranas de ser engullidas. https://whatsapp.com/channel/0029VaYKhdv5q08fphYVt40M En una caminata por una húmeda selva peruana en 2016, Kim Roelants, bióloga de [...]

Researchers analyzed a skull found in Montana of a plant-eating member of the ceratops family, finding distinct traits. In the Late Cretaceous period, a remarkable flowering of horned dinosaurs occurred [...]

Dice snakes found on an island in southeastern Europe fully commit themselves to the role of ex-reptile. Most snakes flee or fight when attacked. Then there are the dice snakes [...]

Las serpientes de dados encontradas en una isla del sureste de Europa incluso sangran por la boca para fingir su muerte. La mayoría de las serpientes huyen o pelean cuando [...]

These reptiles and their social networks are understudied, according to researchers applying scents to different snakes to assess their behavior. Say the words ''animal self-recognition,'' and many scientists will think [...]

Scientists built a working model of an early winged dinosaur to test a hypothesis about how the appendages evolved. The origin of bird wings has long presented a puzzle to [...]

Researchers say the species they named Tyrannosaurus mcraeensis predated the dinosaur era's great predator. A team of researchers have announced the discovery of a new species of Tyrannosaurus from New [...]

New research is trying to remake the case that fossils known as Nanotyrannus were their own species, rather than a teenage Tyrannosaurus rex. It is only 23 inches long, but [...]

An analysis by researchers in China found that weather disasters might be helping nonnative animals replace native species in the wild. A new analysis published this week suggests that extreme [...]

Remnants of decaying tiny animals were colonized by others in an interspecies interaction dating back 480 million years. The bodies of the dead drift to the bottom of the ocean, [...]

Most people come to Ox Ranch -- an 18,000-acre property outside Uvalde, Texas -- for the thrill of hunting exotic animals in the Hill Country. But the ranch is also [...]

The discovery suggests that long necks, which helped some prehistoric reptiles catch food, were tempting targets for predators. In 1830, Henry De la Beche, an English paleontologist, composed a painting [...]

Researchers just discovered that the spiny mouse was concealing bony plates beneath the skin over its tail. At first it looks like a slightly more hairy rodent. But the spiny [...]

The arachnids, which probably migrated to the United States from South Africa, seem to be attacking black widow spiders in some parts of the country. Few spiders in the United [...]

Bottlenose dolphins help Brazilian fishermen pull in their catch, and researchers have worked out what the marine mammals get from the cooperative hunting. Every summer in waters off the town [...]

A new paper suggests an ancient creature's odd anatomical feature may be the earliest known example of specialized sexual combat in the animal kingdom. Walliserops trifurcatus wasn't like the other [...]

How smushed shells could help to resolve paleontological mysteries. You never know where a bit of unusual scientific research is going to lead. Consider a https://onlinelibrary.wiley.com/doi/10.1002/jez.1773. Researchers subjected the skeletal [...]

In a Congolese national park, great apes of different species interact socially, with individuals clearly recognizing one another. In the misty forests of the Congolese rainforest, a small band of [...]

Mention the ocean, and it's hard not to think of jaws. The deep waters contain many tooth-lined mouths: the bear-trap maws of sharks and dolphins, the slack lips of shoaling [...]

A 3-D model developed by researchers suggests that the extinct megashark was fiercer than paleontologists previously imagined. Five million years ago, immense predatory sharks patrolled the oceans. Their giant teeth [...]

Feral burros wreck wetlands in the desert national park. But a study found that when mountain lions prey on them, the donkeys may help some terrain thrive. Early on a [...]

Antlers, the headgear of deer, moose and elk, are more useful for display than combat. But that does not stop deadly lockups from occurring. As the days of summer days [...]

Scientists directly measured the metabolic rate of extinct animals, which revealed that some giant dinosaurs became coldblooded. Paleontologists have long wrangled with the question of dinosaur metabolisms -- whether they [...]

Researchers described Annakacygna, a family of flightless ancient swans that were filter-feeders. It's not unusual today to find swans on rivers and lakes, splitting their time between pulling up water [...]

The premise, put forth in a new paper, highlights an assortment of tensions in dinosaur paleontology, including how subjective the naming of species can be. Tyrannosaurus rex is the most [...]

Paleontologists in China found pellets of undigested food -- just like ones owls leave behind -- preserved with pterosaur fossils. Fur, bones, feathers and scales can be murder on the [...]

A study of fossils from Colombia suggests that a prehistoric shellfish hunted prey with remarkably sharp vision. Modern, adult crabs are not renowned for their swimming ability or their vision. [...]

While ankylosaurs are already known for their armor and club tails, this specimen from South America had a unique way of fighting predators. It's not every day you find a [...]

So-called ''penis worms'' get attention for all the wrong reasons. But new research finds they may have been early pioneers in a creative survival technique. Consider this evolutionary dilemma, faced [...]

A new study reveals how some mammals evolved nature's most impressive chompers (which are not always used for chomping). Elephants have them. Pigs have them. Narwhals and water deer have [...]

The southern cassowary is often called the world's most dangerous bird. While shy and secretive in the forests of its native New Guinea and Northern Australia, it can be aggressive [...]

Titanokorys gainesi, turned up in the Canadian Rockies, was among the largest known predators 500 million years ago. Some 506 million years ago, a predator swept over the silt bottoms [...]

That this perennial wildflower digests trapped insects suggests that other plants' appetites for animals may be overlooked. This wildflower looks innocent. Found in wetlands not far from major cities in [...]

Excavations at Cahokia, famous for its pre-Columbian mounds, challenge the idea that residents destroyed the city through wood clearing. A thousand years ago, a city rose on the banks of [...]

Younger paleontologists are working to overcome some historical legacies of their discipline and change how people learn about natural history. In 2019, Mohamad Bazzi, a doctoral student at Uppsala University [...]
