The rise of the Rocky Mountains and the arrival of a seaway that divided North America into three distinct sections may have been the catalyst for the evolution of new species of dinosaurs.
In a first of its kind study, researchers from Vanderbilt University found that mammals’ best defense to adapting to climate change was diversity, and families with higher taxonomic diversity were better able to survive ongoing environmental changes.
The second-largest mass extinction in Earth's history coincided with a short but intense ice age during which enormous glaciers grew and sea levels dropped.
The dinosaurs of the Cretaceous may have faced an unexpected hazard: fire!
New research suggests that some mammals flourished during the last 20 million years of the dinosaurs' reign.
Conventional wisdom holds that during the Mesozoic Era, mammals were small creatures that held on at life's edges.
The world’s oceans may be acidifying more rapidly than they have at any time in the past 300 million years due to high levels of pollution, according to research published this week in the journal Science.
The ancient sifrhippus, the earliest known horse, lived around 50 million years ago. It was very distinct in its appearance because it was only about the size of a modern day house cat, weighing in around 12 pounds.
A strange tulip-shaped creature discovered in half-a-billion-year-old rocks had a feeding system unlike any other animal, researchers reported this week.

Mapinguari The mapinguari or mapinguary is an ape-like cryptid said to inhabit the Amazon rainforests of Brazil and Bolivia. It is also known as the Isnashi. Several attempts to find physical evidence that the creature exists have been conducted. Samples have been gathered, but when analyzed it was found to be from known animals and some of the castings of tracks were inconclusive. Native folklore has described the creature as having only one eye, long claws, backward feet, a...
Palaeovespa is a genus of wasps that holds seven species, all of which are extinct. Two of the species were discovered in Baltic amber deposits from Europe dating back to the middle Eocene era, while the other five were found in Florissant Formation amber from the Priabonian stage era in Colorado in the United States. This genus, and four of its species, was first described in 1906 by Dr. Theodore Cockerell in the Bulletin of the Museum of Comparative Zoology. Cockerell described all but one...
Australopithecus africanus was an early hominid, an australopithecine that lived between roughly 3.03 and 2.04 million years ago in the later Pliocene and early Pleistocene. Au. africanus was of slender build and was thought to have been a direct ancestor of modern humans. Fossil remains signify that Au. africanus was considerably more like modern humans that Au. afarensis, with a more human-like cranium permitting a larger brain and more humanoid facial features. This hominid has only been...
Thescelosaurus, meaning “godlike”, “wondrous”, or “marvelous” and “lizard” was a genus of small ornithopod dinosaur that appeared at the very end of the Late Cretaceous period in North America. It was a member of the last dinosaurian fauna before the Cretaceous-Paleogene extinction event around 65.5 million years ago. The completeness and preservation of many of its specimens illustrate that it might have preferred to live near streams. This bipedal ornithopod is known from...
Daspletosaurus, meaning “frightful lizard” is a genus of tyrannosaurid theropod dinosaur that resided in western North America between 77 and 74 million years ago, during the Late Cretaceous Period. Fossils of the only named species were found in Alberta, although other possible species from Alberta and Montana wait for description. Daspletosaurus is closely related to the much larger and more current Tyrannosaurus. Like most of the known tyrannosaurids, it was a multi-ton bipedal...
