A nearly complete fossil of a prehistoric marine reptile with preserved soft tissue has been found in central-western Colombia, at a spot several hundred miles from the Caribbean coast, a university in this capital said. Experts have given the reptile the name “Eonatator coellensis” because the find was made in a dry stream bed in […]

Life Possible On Earth 3.2 Billion Years Ago
A spark from a lightning bolt, interstellar dust, or a subsea volcano could have triggered the very first life on Earth. But what happened next? Life can exist without oxygen, but without plentiful nitrogen to build genes — essential to viruses, bacteria and all other organisms — life on the early Earth would have been […]
Docofossor,Agilodocodon : mammal fossils discovered
The fossils of two interrelated ancestral mammals, newly discovered in China, suggest that the wide-ranging ecological diversity of modern mammals had a precedent more than 160 million years ago. With claws for climbing and teeth adapted for a tree sap diet, Agilodocodon scansorius is the earliest-known tree-dwelling mammaliaform (long-extinct relatives of modern mammals). The other […]
Swimming reptiles make their mark in the Early Triassic
Vertebrate tracks provide valuable information about animal behavior and environments. Swim tracks are a unique type of vertebrate track because they are produced underwater by buoyant trackmakers, and specific factors are required for their production and subsequent preservation. Early Triassic deposits contain the highest number of fossil swim track occurrences worldwide compared to other epochs, […]
15-million-year-old mollusk protein found
A team of Carnegie scientists have found “beautifully preserved” 15 million-year-old thin protein sheets in fossil shells from southern Maryland. Their findings are published in the inaugural issue of Geochemical Perspectives Letters. The team–John Nance, John Armstrong, George Cody, Marilyn Fogel, and Robert Hazen–collected samples from Calvert Cliffs, along the shoreline of the Chesapeake Bay, […]
NOW Explains Earth’s magnetic field
Earth’s magnetic field is crucial for our existence, as it shields the life on our planet’s surface from deadly cosmic rays. It is generated by turbulent motions of liquid iron in Earth’s core. Iron is a metal, which means it can easily conduct a flow of electrons that makes up an electric current. New findings […]
Evolution: Rock sponges split up
A study led by researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich throws new light on the evolution of the so-called rock sponges, and reveals that conventional, morphology-based taxonomies do not accurately reflect the true genealogical relationships within the group. Modern approaches to biological systematics have demonstrated that the evolutionary relationships between organisms can best be teased […]
Geophysicists find reason for sudden tectonic plate movements
Yale-led research may have solved one of the biggest mysteries in geology — namely, why do tectonic plates beneath the Earth’s surface, which normally shift over the course of tens to hundreds of millions of years, sometimes move abruptly? A new study published Jan. 19 in the journal Proceedings of the National Academy of Sciences […]
Dino-killing asteroid generated global firestorm ?
Pioneering new research has debunked the theory that the asteroid that is thought to have led to the extinction of dinosaurs also caused vast global firestorms that ravaged planet Earth. A team of researchers from the University of Exeter, University of Edinburgh and Imperial College London recreated the immense energy released from an extra-terrestrial collision […]
Nundasuchus: A reptiles lived before dinosaurs
Finding a new species of dinosaur is pretty rare. Getting a hand in the discovery and naming of one — that’s rarer still. Or it would be for anyone other than 32-year-old Sterling Nesbitt, an assistant professor of geological sciences in the College of Science and the newest addition to Virginia Tech’s paleontology team. Nesbitt […]
