New Cretaceous fossils shed light on the early evolution of ants
2016-05-30 12:00:00| LifeSciencesWorld
[NEWS] Ants comprise one lineage of the triumvirate of eusocial insects and experienced their early diversification within the Cretaceous. The success of ants is generally attributed to their remarkable social behavior. Recent studies suggest that the early branching lineages of extant ants formed small colonies of either subterranean or epigeic, solitary specialist predators. The vast majority of Cretaceous ants belong to stem-group Formicidae and comprise workers and repro…

Antarctic Fossils Suggest That Mass Extinction Event in Polar Regions as Rapid as Elsewhere
2016-05-27 22:03:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: A new study, published in the journal Nature Communications revealed that animals living in the Polar Regions suffered from the sudden and deadly effect of the mass extinction event just like elsewhere in the world. Previously, scientists believe that animals in the Polar Regions are far enough away from the cause of the extinction to be badly affected. They also proposed that organisms living in the poles would have been more resilient to global climatic changes associated with an asteroid impact...

Fossils of North America&s first monkey species found
2016-04-23 12:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Mother Nature Network: It might not seem so extraordinary to find fossils of a monkey species in Panama. Today, the country is home to eight species of monkey. But consider this: The fossil evidence found of this ancient South American monkey species dates back 21 million years, well before the isthmus of Panama connected North America to South America. Somehow, this species managed to cross 100 miles of water from South America up to North America. And it did so about 18 million years earlier than the earliest known...

Australopithecus fossils found east of the Great Rift Valley
2016-03-24 11:00:00| LifeSciencesWorld
[NEWS] New fossils from Kenya suggest that an early hominid species — Australopithecus afarensis — lived far eastward beyond the Great Rift Valley and much farther than previously thought. An international team of paleontologists led by Emma Mbua of Mount Kenya University and Masato Nakatsukasa of Kyoto University report findings of fossilized teeth and forearm bone from an adult male and two infant A. afarensis from an exposure eroded by the Kantis River in Ongata-Rong…
