Scientists Unlock the Secrets of Crocodile Skin and Its Irregular, Mystifying Patterns

The scales on crocodiles’ heads are very different from the skin appendages of other animals and even distinct from the scales on the rest of their bodies

A fossil skull of a prehistoric amphibian, found in a 230-million-year-old burrow in Wyoming, turned out to be from an unknown species.

A Paleontologist Cracked Open a Rock and Discovered a Prehistoric Amphibian With a Clever Survival Strategy

Named “Ninumbeehan dookoodukah” by Eastern Shoshone students and elders, the creature burrowed in riverbeds to stay moist during extreme droughts

An illustration of two Skiphosoura bavarica in flight shows how the reptiles might have appeared in Jurassic skies.

Paleontologists Discover a New Pterosaur, Filling a Key Gap on the Evolutionary Timeline for These Flying Reptiles

Revealed by a German fossil, the newly described species sheds light on questions that scientists have been puzzling over for nearly two centuries

By examining the fossils of ancient creatures, scientists are able to see the origins of features that make mammals different from other animals.

How to Make a Mammal in Nine Evolutionary Steps

From the formation of inner ear bones to the rise of hair to cover our bodies, these developments made us distinct from other animals

Silesaurids—including Silesaurus opolensis (pictured above) and the newly described fossil from Brazil (not pictured)—are usually considered non-dinosaurs. Some researchers are suggesting they might be more closely related to certain dinosaurs than previously thought.

A Rare Triassic Fossil Found in Brazil Could Shed Light on the Origin of Dinosaurs

The 237-million-year-old remains are among the oldest silesaurid fossils ever found, adding to paleontologists’ understanding of this still-mysterious group of prehistoric reptiles

The researchers studied the dusky lory (pictured) and the rosy-faced lovebird.

A Simple Chemical Shift Explains Why Parrots Are So Colorful, Study Suggests

Unlike other birds, which get pigments from their diets, parrots produce their own—but scientists never fully understood the underlying mechanisms, until now

A team of roboticists, paleontologists and biologists are building robots to simulate crucial evolutionary developments that can’t be tested with static fossils

A 2007 illustration of Arthropleura, the largest known arthropod, which grew nearly as large as a car. New research suggests previous visualizations of the animal's head were incorrect.

Fossils Reveal the Face of an Extinct Nine-Foot-Long ‘Millipede,’ the Largest Arthropod to Ever Live

Scientists in France solved the evolutionary mystery of this prehistoric monster, which resembles both the centipedes and millipedes of today

Two comb jellies have fused together and are being probed by a pipette.

These Frankenstein-Like Sea Creatures Can Actually Fuse Their Bodies Together

Two comb jellies can merge their digestive and nervous systems and even sync their bodily functions, according to new research. The discovery could have implications for human medicine

A new study suggests that coyotes, like the ones seen here, have the same face muscle as dogs that's used to make pleading "puppy eyes."

Coyotes Might Make ‘Puppy Eyes,’ Suggesting the Facial Expression Evolved for More Than Just Cuteness

The wild canines have the same muscles used by domestic dogs to create the wide-eyed, pleading look that captures humans’ hearts

Some species of sea robins, such as Prionotus carolinus, use their leg-like appendages to dig out and taste prey beneath the sand. 

These Fish Have Legs—and They Can Use Them to Taste Prey

Sea robins have “the body of a fish, the wings of a bird and multiple legs like a crab”

Recent genetic research could be used to produce plants without prickles, making it easier for gardeners to pluck roses without getting jabbed.
