A new study shown that meteorite impacts on ancient oceans may have created nucleobases and amino acids. Researchers from Tohoku University, National Institute for Materials Science and Hiroshima University discovered this after conducting impact experiments simulating a meteorite hitting an ancient ocean. With precise analysis of the products recovered after impacts, the team found the […]

Montsechia, first aquatic angiosperm ?
Indiana University paleobotanist David Dilcher and colleagues in Europe have identified a 125 million- to 130 million-year-old freshwater plant as one of earliest flowering plants on Earth. The finding, reported Aug. 17 in the Proceedings of the National Academy of Sciences, represents a major change in the presumed form of one of the planet’s earliest […]
How do continents break up?
When the western part of the super-continent Gondwana broke up around 130 Million years ago, today’s Africa and South-America started to separate and the South Atlantic was born. It is commonly assumed that enormous masses of magma ascended from the deep mantle up to higher levels, and that this hot mantle plume (the Tristan mantle […]
Ichibengops : pre-mammal fossils from Zambia
Scientists at The Field Museum have identified a new species of pre-mammal in what is now Zambia. Thanks to a unique groove on the animal’s upper jaw, it was dubbed Ichibengops (Itchy-BEN-gops), which combines the local Bemba word for scar (ichibenga), and the common Greek suffix for face (ops). Put simply: Scarface. Believed to be […]
Big dinosaur discoveries in tiny toothy packages
Researchers have examined one of the smallest parts of the fossil record–theropod teeth–to shed light on the evolution of dinosaurs at the end of the Cretaceous. Findings published in the journal Acta Palaeontologica Polonica have effectively quadrupled the dinosaur diversity in the area of study, eight localities from Treviño County, Huesca and Lerida–including the exceptional […]
Dinosaur fossil resembling the ‘loch ness myth’ found in Alaska
Researchers in Alaska have uncovered the bones of a prehistoric marine reptile dating back 70 million years. This is the first time an elasmosaur has ever been unearthed in this state. Its vertebrae were discovered embedded in an eroding cliff. Elasmosaurs had extremely long necks, small heads and paddle-shaped limbs for swimming. There are many theories […]
fastest mammal evolution in Jurassic period
Mammals were evolving up to ten times faster in the middle of the Jurassic than they were at the end of the period, coinciding with an explosion of new adaptations, new research shows. Early mammals lived alongside the dinosaurs during the Mesozoic era (252-66 million years ago). They were once thought to be exclusively small […]
Trajectory of Nepal earthquake
Researchers from Scripps Institution of Oceanography at UC San Diego have accurately mapped out the movement of the devastating 7.8-magnitude Nepal earthquake that killed over 9,000 and injured over 23,000 people. Scientists have determined that the earthquake was a rupture consisting of three different stages. The study could help a rapidly growing region understand its […]
Most ancient pinworm yet found ?
An egg much smaller than a common grain of sand and found in a tiny piece of fossilized dung has helped scientists identify a pinworm that lived 240 million years ago.It is believed to be the most ancient pinworm yet found in the fossil record. The discovery confirms that herbivorous cynodonts — the ancestors of […]
Ancient marine ecosystem uncovered
Hidden secrets about life in Somerset 190 million years ago have been revealed by researchers at the University of Bristol and the Bath Royal Literary and Scientific Institution (BRLSI) in a new study of some remarkable fossils. Thanks to exceptional conditions of preservation, a whole marine ecosystem has been uncovered — and yet it was […]
