A project to replace the boardwalk at the Mill Canyon Dinosaur Tracksite in Moah, Utah, cause minor damage to tracks and trace fossils at the site, a Bureau of Land Management paleontologist found.
A team of scientists dated the footprints along an extinct lake bed in New Mexico and found them to be between 21,000 and 23,000 years old — far older than reliable evidence has suggested to date.
Millions of years ago Nevada was home to a variety of dinosaurs, but it had long been thought none of those were unique to the state. That just changed. First discovered in 2008, fossilized bones of the creature were pieced together over the last 13 years. It’s now verified and certified, and it has been named Nevadadromeus Schmitti, a plant-eating animal the size of a large dog.
Scientists have identified an aggressive bone cancer — for the first time — in the fibula of a dinosaur that lived 76 to 77 million years ago. The diagnosis sheds new light on dinosaurs and disease.
A new study of dinosaur eggs as well as a football-sized egg from Antarctica shows how some ancient creatures relied on soft shells rather than hard ones.
A new analysis of what were initially thought to be microbial fossils in Greenland suggests they might instead just be mineral structures created when ancient tectonic forces squeezed stone.
Modern birds are dinosaurs without toothy jaws, and with bigger brains. Newly published research fills in some of the missing links in their evolution.
Scientists have discovered the proboscis butterflies use to suck nectar from flowers existed before flowers did. So: What were ancient butterflies using their long, tongue-like suckers for?
The tick was with a feather from a dinosaur that lived in the Cretaceous Period. Modern ticks love to bite mammals, and scientists have long wondered what the tiny vampires ate millions of years ago.
Even after a Harvard team took into account differences in age and weight among ancient specimens and knees today, they found that modern humans tend to have more osteoarthritis.
They were ugly. And, unfortunately, they were not equipped with an anus. But the sand dwellers could be an important part of filling in our own early evolutionary tree.
The creature, which roamed ocean floors over 500 million years ago, went years without a definitive scientific classification. Now, researchers think the oddball finally has a group to call its own.
Early stages of dinosaur development remain a mystery. However, researchers have uncovered a new way to study the early stages using the teeth of fossilized dinosaur embryos.
A small rock might contain tissue from a 130 million-year-old dinosaur brain. If confirmed, it would be the first bit of fossilized dino gray matter ever found.
Microleo attenboroughi was a tiny, marsupial lion that lived some 18 million years ago. Paleontologists in Australia said they named it after the famed naturalist "for his dedication and enthusiasm."
Long before cooking was common, early humans needed extra energy to fuel bigger bodies and brains. Scientists say simple stone cutting tools likely allowed small-toothed meat eaters to thrive.
Deep inside a rocky chamber, reached by a narrow crevice, researchers found more than 1,500 fossilized bones of what may be the gravesite of a creature never before identified by science.
Genetic sleuthing and comparisons of recently discovered fossils with living snakes point to a "protosnake" ancestor that likely had tiny hind legs and lived about 120 million years ago.
Hoping to help trace the history of how velociraptors evolved into birds, researchers at Harvard and Yale may have tracked a key beak transformation to two genes.
