Fossil remains have been discovered in the Riversleigh World Heritage Area of Queensland, Australia, and appear to belong to a new kind of tiny marsupial lion.

Scientists say their research shows that two subspecies of songbirds found only on the Galápagos Islands should be elevated to full species status.

Israel’s flora and fauna are quite diverse in relation to the country’s size, but they are rapidly dwindling, according to a report by the Environmental Protection Ministry.

Many of the world's biggest and iconic animals such as the Bengal tiger could be extinct by the end of the century if drastic conservation measures are not taken, a new study has warned.

From the late Pleistocene to the Holocene and now the so-called Anthropocene, humans have been driving an ongoing series of species declines and extinctions. Large-bodied mammals are typically at a higher risk of extinction than smaller ones. However, in some circumstances, terrestrial megafauna populations have been able to recover some of their lost numbers because of strong conservation and political commitment, as well as human cultural changes. Indeed, many would be in considerably worse predicaments in the absence of conservation action.

A new species of extinct flesh-eating marsupial that terrorised Australia's drying forests about 5 million years ago has been identified from a fossil discovered in remote northwestern Queensland.

Scientists believe that the meteorite impact blamed for the extinction of most life on Earth at the time, may have actually kicked off a literal "Dark Age" that became the ultimate factor.

The mass extinction of life 66 million years ago at the Cretaceous/Paleogene boundary, marked by the extinctions of dinosaurs and shallow marine organisms, is important because it led to the macroevolution of mammals and appearance of humans. The current hypothesis for the extinction is that an asteroid impact in present-day Mexico formed condensed aerosols in the stratosphere, which caused the cessation of photosynthesis and global near-freezing conditions. Here, we show that the stratospheric aerosols did not induce darkness that resulted in milder cooling than previously thought.

By quarrying limestone hills for raw materials, cement companies are invariably destroying the only habitat of many snails, wiping out entire species at one go, conservationists allege.

Species across the world are rapidly going extinct due to human activities, but humans are also causing rapid evolution and the emergence of new species.
