Researchers have recently unearthed fossils of an extinct wildebeest-like creature named Rusingoryx that boasted a strange nasal structure similar to that of duck-billed dinosaurs.
Pink deep-sea worms previously represented by only a single species have puzzled biologists for nearly six decades. However, four new worms recently spotted near California and Mexico have helped scientists properly place the creatures along the evolutionary tree of life.
Fossils belonging to a prehistoric butterfly-like species were recently found in China and eastern Kazakhstan. This insect, researchers say, predates modern butterflies by about 40 million years and is an example of convergent evolution.
Researchers have finally revealed what gave the extinct Pink-headed Duck its unique-colored plumage.
There is more to determining an animal's intelligence than brain size. A new study from the University of Toronto found an ancient rodent species had a large brain that was even heftier than those of some primitive primates of the same era, but it wasn't necessarily "smarter."
Black squirrels have been seen more regularly in Michigan -- many residents have even mistaken them for rats with bushy tails. Despite their unique color, however, they are still gray squirrels. They seem to occur more often in northern climates, and a project looks at them in the U.K.
An ancient rabbit ancestor thought to exist only in Europe was recently found in present-day Siberia. The dsicovery spotlights the evolution of the species as well as how landmasses were shifting 14 million years ago during the Miocene era.
A new duck-billed dinosaurs found in Alabama suggest the species originated in the eastern U.S. Researchers say finding such rare fossils is really important for understanding how the dinosaurs spread across the world.
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.
Researchers found domestic dogs can tell the difference between a threatening and pleasant facial expression by gazing into one's eyes. This is similar to a human's social gazing behavior.
Mammals have evolved much more sensitive hearing than their reptile-like ancestors thanks to three super tiny bones tucked away in the auditory canal. But researchers are still unsure how the mammalian middle ear evolve. Now the University of Queensland (UQ), is shedding some light on the matter, challenging current beliefs and calling for further fossil evidence.
Human friendship is not as unique as previously thought, say researchers who tested chimpanzees and found that they are more likely to share with those they trust and consider friends.
A complete dinosaur skeleton of a baby Chasmosaurus has revealed some interesting characteristics of horned dinosaurs, which are characterized by a large bony appendage known as a frill.
A dinosaur species known Protoceratops andrewsi sported an ornamental head appendage called a frill that was likely used to attract suitable mates and helped to assert social dominance.
