An isotopic analysis of juvenile Siberian woolly mammoth tusks suggests that the prehistoric mammals went extinct as a result of excess hunting, not climate change.
Multiple baby duck-billed dinosaurs, identified as Saurolophus angustirostris, were recently excavated from “Dragon's Tomb" in Mongolia.
Researchers from the University of Bonn suggest that a prehistoric mammal, Spinolestes, may have suffered from hair loss. This fungal disease is commonly seen in many of the species' modern descendants.
A new species recently added to the desmostylia group suggests that the hippo-sized suction-feeders were a more diverse group of animals than previously thought and ate in a very unique way.
A new study confirms that a well-preserved fetus and soft tissues were found in 48-million-year-old fossils of a small horse-like species.
Paleontologists from the University of Michigan recently excavated almost 20 percent of a complete woolly mammoth skeleton from a local wheat field. The discovery was made by farmer and landowner who was digging to install a drainage pipe.
Using well-preserved 800-year-old seeds, students have successfully revived an extinct species of squash.
Dinosaur extinction was caused by an asteroid impact 66 million years ago that also triggered a series of volcanic eruptions, say researchers from the University of California Berkeley.
Using fossilized structures known as melanosomes, researchers concluded that an ancient bat species was reddish-brown in color. More importantly, the study suggests that melanin desposits from fossils can be used to determine the color of ancient species.
Western Serpentiform Skinks, a remote species that looks like a snake but has the arms and tongue of a lizard, have been considered extinct for a long time. But a recent photographed sighting in Kenya suggests there is hope – and more to learn about this reclusive species.
A 260-million-year-old fossil species Eunotosaurus africanus sheds new light on turtle evolution. Details of its skull provide the real clues.
A now-extinct monkey's one-million-year-old fossil was found embedded in limestone in an underwater cave in the Dominican Republic. This adds to findings about New World monkeys in the Caribbean.
In the Caribbean, which has no salamanders, one of the amphibians was recently found preserved in amber from 20 million to 30 million years ago.
Our writer James Sullivan talks about how a wooly mammoth could potentially roam Siberia, and the ethics of such cases.
It's official: the rare and elusive "eastern puma" has been removed from the list of North American wildlife protected under the Endangered Species Act. Traditionally, this would imply a recent loss or success for conservationists, but not so with this top cat. In fact, officials have revealed that the cougar in question may have been extinct for decades.
