Researchers have finally revealed what gave the extinct Pink-headed Duck its unique-colored plumage.
An extinct marine crustacean-like creature known as Dollocaris ingen was equipped with two large eyes, each about a quarter of its body size. Researchers say this likely gave the pipsqueak an advantage when ambushing its prey.
Earth's largest apes died off because they could not adapt to a new diet forced by climate change 100,000 years ago.
A meter-long shell belonging to a glyptodont – a giant prehistoric kind of armadillo – was found recently along a riverbank in Buenos Aires, Argentina.
Fossil remains of a five-foot-long tortoise suggest the Andes Mountains sat less than a kilometer above sea level 13 million years ago, when the climate was much wetter than it is today. Understanding the past could help researchers predict future climate changes.
An extinct group of marine reptiles known as plesiosaurs had a very unique body structure. New computer simulations suggest the animals likely used it to move through the water like a penguins.
Even though Lonesome George -- the last member of the Pinta Island Galapagos Tortoises -- died in 2012, scientists may be able to revive his species with the genetic help of close relatives.
After analyzing a fossilized three-horned skull and dental remains, researchers have classified Xenokeryx amidalae as an ancient species is actually a distant relative of modern giraffes.
When tracing evolutionary history of gourd seeds, researchers found that the disappearance of large animals directly correlated to changes in distribution of the wild plants.
Recently unearthed arthropod fossils were found to contain traces of brain fragments. Contrary to common scientific belief, the finding proves brains can withstand fossilization.
A newly examined fossil sea urchin represents the oldest known specimen of its kind. This suggests that modern sea urchins diversified from their extinct ancestors ten million years earlier than researchers previously thought.
"Large herbivores are not merely victims of the circumstances they live in, but actively engineer their environment," said Liesbeth Bakker, lead author of the study from the Netherlands Institute of Ecology.
Newly discovered fossils indicate that giant sharks swam throughout ancient oceans 170 million years earlier than researchers previously thought.
Giant prehistoric teeth from an extinct species of shark known as Megalodon recently washed up on a beach in North Carolina. Since little is known about this ancient species, the newly discovered teeth may help researchers unlock more clues.
