Millions of years ago, a bizarre, pouched super-predator terrorized South America with huge saber-like teeth.
The forces of climate change are redefining what it means for a species to be endangered, according to a new study in the open access journal PLOS ONE.
The death of individual species is not the only concern for biologists worried about groups of animals, such as frogs or the "big cats," going extinct.
In a new extensive study scientists explore the diversity within the New Zealand Lepidiums oleraceum and allied species.
Although scientists have known since the middle of the 19th century that the tropics are teeming with species while the poles harbor relatively few, the origin of the most dramatic and pervasive biodiversity on Earth has never been clear.
In a study published today in the journal PLOS ONE, a team of researchers led by NJIT Associate Professor Gareth Russell has applied a novel method for linking large-scale habitat fragmentation to population sustainability.
The dream of bringing woolly mammoths back to life has been a bit of a stretch. But a new discovery in Russia's Far East is providing the best chance of that becoming a reality yet.

The Hawaiian Rail (Porzana sandwichensis), known also as the Hawaiian Crake or the Hawaiian Spotted Rail, was a rather enigmatic species of minuscule rail that resided on Big Island of Hawaii, but is currently extinct. A dark form and a lighter form are known. There is considerable confusion by the existence of two distinct forms. While it can’t be completely excluded that early specimens were collected on another island, only O’ahu and Kaua’I seem plausible given the history of...
The Waitoreke is a cryptid from New Zealand described as being otter-like. Its name derived from “Wai” is a Maori word for water. The rest of the word has different translations, but the common one is “toreke,” which means to disappear. Together the name could translate into “disappears into water” or another translation is a “disappearing water specter.” The usual description is a small otter-like creature about the size of a cat. It has brownish short fur and short...
The Red Rail (Aphanapteryx bonasia) is an extinct and flightless rail. It was native to the Mascarene island of Mauritius, east of Madagascar within the Indian Ocean. It had a close relative on Rodrigues Island, the likewise extinct Rodrigues Rail, with which it’s sometimes considered congeneric. Its relationship with other rail isn’t clear. Rails frequently evolve flightlessness when adapting to isolated islands. It was slightly larger than a chicken and had reddish and hair-like...
Commonly known as the Eurasian cave lion or the European cave lion, Panthera leo spelaea is an extinct subspecies of lion. It is thought to have lived during the Pleistocene epoch, and may have lived in the Balkans in southeastern Europe until 2,000 years ago. The range of this cave lion would have included northwestern North America, Asia, and areas of Europe and would have extended from Germany, Spain, and Great Britain to the Yukon Territory. Its range also extended from Turkistan to...
The short-faced bear is an extinct genus of bears that was native to North America during the Pleistoscene era. Other common names include Arctodus and the bulldog bear. There are two subspecies of the short-faced bear, and one of them, Aroctodus simus, is thought to have been the largest terrestrial mammal on earth. Placed into a group of bears known as running bears or the tremarctine bears, this genus was found in Europe and the Americas. The earliest member of the tremarchtine group,...
