Pygmy tarsiers are among the rarest of the many tarsier species in Asia and the Pacific. In fact, they we believed extinct until two Indonesian scientists trapping rats in Sulawesi accidentally trapped and killed one in 2000. But that was a dead specimen. Scientists from Texas A&M University have reported captured three live animals from Sulawesi.

University of Alberta scientists contend they have the answer to mass extinction of animals and plants 93 million years ago. The answer, research has uncovered, has been found at the bottom of the sea floor where lava fountains erupted, altering the chemistry of the sea and possibly of the atmosphere.

If you are curious about Earth's periodic mass extinction events such as the sudden demise of the dinosaurs 65 million years ago, you might consider crashing asteroids and sky-darkening super volcanoes as culprits.

A beautiful black, white and yellow butterflyfish, much admired by eco-tourists, divers and aquarium keepers alike, may be at risk of extinction, scientists have warned.

The most detailed three-dimensional seismic images yet of the Chicxulub crater, a mostly submerged and buried impact crater on the Mexico coast, may modify a theory explaining the extinction of 70 percent of life on Earth 65 million years ago.

Twenty-five percent of all bird species in the United States are at risk of extinction, according to a report by the National Audubon Society and American Bird Conservancy, the nation's leading bird conservation groups. WatchList 2007 is a compilation of the most endangered birds in the United States.

A brightly coloured tropical frog under threat of extinction is the focus of a new research project hoping to better understand how environment and diet influence its development and behaviour.

Approximately 250 million years ago, vast numbers of species disappeared from Earth. This mass-extinction event may hold clues to current global carbon cycle changes, according to Jonathan Payne, assistant professor of geological and environmental sciences.

The ancient gray wolves of Alaska became extinct some 12,000 years ago, and the wolves in Alaska today are not their descendents but a different subspecies, an international team of scientists reports in the July 3 print edition of the journal Current Biology.

The end-Permian catastrophe eliminated a greater proportion of marine animal diversity than any other mass extinction in the geological record.

A team of scientists from WWF and Conservation International (CI) has discovered the world’s largest known population of grey-shanked doucs (Pygathrix cinerea), increasing chances that the Endangered monkey can be saved from extinction.
