New Big-Nosed Horned-Face Dinosaur Discovered

Fossilized remains of a new species of dinosaur were discovered in the Utah desert. The ceratopsid was named Nasutoceratops, which translates to “big-nosed horned face.” It leaved nearly 76 million years ago.

For more on this finding, and to see Dr. Scott next to a reconstruction of Nasutoceratops, visit NBCNews.com.

Fossil Discovery May Be World’s Oldest Known Bird

A fossil uncovered on a farm in China could be the oldest known species from the bird family. This 150-million-year-old fossil was a small feathered dinosaur, a little over three feet tall, named Aurornis xui. Scientists are still in controversy over whether this specimen does qualify as a bird, but if it does than it will be the oldest of the long line of the evolution of birds and flight.

Scientists Discover the Oldest Dome-Skull Dinosaur

A team of scientists have uncovered three dog-sized dinosaur specimens. The fossilized bones, around 85 million years old, were found on a farm in Alberta, Canada. The species, Acrotholus audeti, weighed 85 pounds when it lived and is the oldest known pachycephalosaur from North America and maybe even the world. The Acrotholus audeti had a skull more than two inches thick. Scientists sometimes refer to pachycephalosaurs as thick-headed lizards or bone-headed dinosaurs because of their skulls.

New Study Reveals How Some Dinosaurs Slept

One of the simplest characteristics of dinosaurs that paleontologists still know little about is how they slept.

New studies have shown that when some smaller dinosaurs slept, they curled up much like birds do today. Though most dinosaur fossils are found in the dinosaur “death pose,” some dinosaurs (who have died while they were sleeping) have been found in a roosting position, similar to the sleeping position of most modern birds.

New Research on Appearance of First Rodents

For years, scientists have been disputing about the timing of the first appearance of rodents on Earth.

Recent discoveries of two new fossils are evidence that the earliest rodent species began about 57.7 to 58.9 million years ago. Being one of the most diverse species on earth, this rodent discovery is monumental for scientists to continue to determine the first origins of placental mammals.

Herbivores Were Great Chewers

Researchers are now discovering that giant plant-eaters, such as Hadrosaurids or a Corythosaurus, may have had teeth with grinding surfaces much like a modern day horse or bison. Their teeth were complex, combining up to six types of tissue, and all varying in hardness. Scientists speculate that this is due to their diets, including tough, tooth-gouging particles from plants.

Researchers believe the complex nature of the herbivores teeth is reason that they were so common.
