Baby tuatara, a rare reptile, found on New Zealand mainland

Oh, baby. The discovery of a one-month-old tuatara, a rare reptile descended from lizard-like dinosaurs, has conservationists in New Zealand celebrating. The critter is the first baby tuatara to be spotted on the mainland there in two centuries, since zoologists released 200 adults inside the Kaori Wildlife Sanctuary beginning four years ago in the hope [...]

500-Pound “Chicken from Hell” Dinosaur Once Roamed North America

Skeleton of Anzu wyliei

It stood 11.5-feet tall and tipped the scales at perhaps 500 pounds, with the body of a raptor, the head of a chicken and the crest of a cassowary; it sported big sharp claws and, probably, feathers. That’s the picture emerging from three fossil skeletons that paleontologists say represent a dinosaur species new to science: [...]

Bizarre New “Texas Longhorn” Dinosaur Bolsters Controversial Theory of Dino Diversity

A newly unearthed dinosaur has been called the “Texas longhorn” of its family tree, and it’s not hard to see why: Nasutoceratops titusi, a relative of the famous Triceratops, sported 3.5-foot-long horns, measured 15 feet long from nose to tail, and weighed 2.5 tons. But this fossil is significant for more than just its anatomy–the [...]

Meet the Last Common Ancestor of Bats, Whales, Sloths and Humans

Placental ancestor

They may run, swim or fly. They may weigh less than a penny or more than a dozen school buses. From humans to whales to bats, the placental mammals—so named for the placenta that nourishes the fetus during development—are mind-bogglingly diverse. (The placental mammals are one of three major groups of mammals; the other two [...]

Molecular Analysis Supports Controversial Claim for Dinosaur Cells

RALEIGH—Twenty years ago, paleontologist Mary Schweitzer made an astonishing discovery. Peering through a microscope at a slice of dinosaur bone, she spotted what looked for all the world like red blood cells. It seemed utterly impossible—organic remains were not supposed to survive the fossilization process—but test after test indicated that the spherical structures were indeed [...]

Diminutive Dinosaur Bore Beak, Bristles and Fangs [Video]

Move over platypus, a recently discovered dinosaur may have bested you for the strangest combination of physical features. Two hundred million years ago, a two-foot- long, beaked biped covered in quills scampered about an area that is now part of South Africa. The dinosaur’s discoverer is paleontologist Paul Sereno, of the University of Chicago. Sereno [...]

Yutyrannus huali lived in northeastern China 125 million years ago, according to a group of scientists in China, where three specimens of the bipedal tyrannosaur were found. A description of the new dinosaur [...]

Digital reduction: Newly described dinosaur had only one finger per stubby forelimb

single-fingered dinosaur with one claw per arm

Large tyrannosaurs managed to attain their status in the dinosaur kingdom among theropods wielding just two fingers at the end of their rather reduced arms. But they are now outdone in the realm of digital reduction. In this group where three fingers is the norm, an unusual new dinosaur has come to light that had [...]

Old tracks show protodinosaurs emerged millions of years earlier than previously thought

oldest dinosaur found by tracks in poland Prorotodactylus

Three newly discovered groups of fossilized footprints show that dinosaurs and their early relatives were stalking the Earth some five million to nine million years earlier than scientists had previously estimated. This represents "a substantial extension of early dinosaur history," noted researchers in a description of the find, which was published online October 5 in [...]

Curious carnivorous dinosaur had a humpback

new humbacked dinosaur

Some dinosaurs had feathers; others had extendable claws or elaborate spikes. But a newly described species is the first to have been found with a distinctively humped back. The six-meter-long theropod (Concavenator corcovatus) hunted in modern-day Spain some 125 million years ago. Unlike a camel’s fatty hump, this carnivorous dinosaur’s bump was made of solid [...]

It is described online May [...]
