Pregnant prehistoric fossil offers clues to past
University of Alberta scientists have named a new species of ancient marine reptile, fondly called the Ping Pong Ichthyosaur for the spot the prehistoric creature called home for the last 25 years. Embryos found within the body of a pregnant fossil also mark the most recent record of a live birth and the physically smallest known ichthyosaur embryos.
Ancient birds flew on all-fours
The earliest known ancestor of modern-day birds took to the skies by gliding from trees using primitive feathered wings on their arms and legs, according to new research by a University of Calgary paleontologist.
Dinosaurs' climate shifted too
Ancient rocks from the bottom of the Pacific Ocean suggest dramatic climate changes during the dinosaur-dominated Mesozoic Era, a time once thought to have been monotonously hot and humid.
New study explores role of theater in maya political organization
Magnificent stone sculptures of Classic Maya culture (AD 250-900) have long fascinated archaeologists and the general public alike. But what did the scenes depicted in these monuments mean in their society?
Possible evidence of cell division, differentiation found in oldest known embryo fossils
A group of 15 scientists from five countries has discovered evidence of cell differentiation in fossil embryos that are more than 550 million years old. They also report what appear to be cells about to divide. They used x-ray imaging technologies that produce higher resolutions than hospital-CT scans and digitally extracted cells from the embryos of ancient animals that have been preserved in the Doushantuo Formation, a fossil site in South China.
West australian fossil find rewrites land mammal evolution
A fossil fish discovered in the West Australian Kimberley has been identified as the missing clue in vertebrate evolution, rewriting a century-old theory on how the first land animals evolved.
Researchers give name to ancient mystery creature
For the first time, researchers at the University of Alberta have been able to put a name and a description to an ancient mammal that still defies classification.
Biakker can say a lot in just a few words
'On the other side of the river close to us away from here going backwards'. This intriguing answer from an East Indonesian to the question where the houses in his village used to stand, made the Dutch linguist Wilco van den Heuvel devote extra attention to references to people and objects in his description of the Biak language. This Austronesian language is threatened with extinction.
Oldest complex organic molecules found in ancient fossils
Ohio State University geologists have isolated complex organic molecules from 350-million-year-old fossil sea creatures -- the oldest such molecules yet found.
New evidence of early horse domestication
Soil from a Copper Age site in northern Kazakhstan has yielded new evidence for domesticated horses up to 5,600 years ago. The discovery, consisting of phosphorus-enriched soils inside what appear to be the remains of horse corrals beside pit houses, matches what would be expected from Earth once enriched by horse manure. The Krasnyi Yar site was inhabited by people of the Botai culture of the Eurasian Steppe, who relied heavily on horses for food, tools, and transport.

Geological feature key to finding, protecting tombs
A 42-year-old method for finding water, monitoring pollution and helping with tunneling may also be a way to locate and protect tombs in the Valleys of the Kings and Queens and other burial sites in Egypt, according to Penn State researchers.
Recovering Pompeii
Artists in ancient Pompeii painted the town red 2,000 years ago with a brilliant crimson pigment that dominated many of the doomed city's wall paintings. Now scientists from France and Italy are reporting in the journal Analytical Chemistry why those paintings are undergoing a mysterious darkening. The synchrotron light of the European Synchrotron Radiation Facility (ESRF) in Grenoble (France) has provided new insight into this process and what produces it.
Scientists find lamprey a living fossil
Scientists from the University of Witwatersrand in Johannesburg, South Africa, and the University of Chicago have uncovered a remarkably well-preserved fossil lamprey from the Devonian period that reveals today's lampreys as "living fossils" since they have remained largely unaltered for 360 million years.
Embattled lives: mastodon tusk 'scars' record a history of a combat
Male mastodons engaged in fierce combat with their rivals virtually every year of their adult lives, new analyses of fossil tusks reveal. The battles took place in mid-spring to early summer and seem to correspond to behavior shown by modern-day bull elephants in musth—an annual phase of heightened aggression and sexual activity.
Varied diet of early african homind casts doubt on extinction theory
An upright hominid that lived side by side with direct ancestors of modern humans more than a million years ago had a far more diverse diet than once believed, clouding the notion that it was driven to extinction by its picky eating habits as the African continent dried, says a new University of Colorado at Boulder study.
Teeth tell ancient tale
University of Arkansas researchers examined the dental landscapes of prehistoric creatures from a South African province and found evidence for a dietary shift that suggests a corresponding change in the type of landscape that surrounded them. This marked change in the prehistoric landscape from woods and shrubs to grasslands may help fill in the picture of environmental changes that accompanied our own evolution.
Radiologists attempt to solve mystery of tut's demise
Egyptian radiologists who performed the first-ever computed tomography (CT) evaluation of King Tutankhamun's mummy believe they have solved the mystery of how the ancient pharaoh died.
Mystery of ancient astronomical calculator unveiled
An international team has unravelled the secrets of a 2,000-year-old computer which could transform the way we think about the ancient world.
World's oldest ritual discovered
A startling archaeological discovery this summer changes our understanding of human history. While, up until now, scholars have largely held that man's first rituals were carried out over 40, 000 years ago in Europe, it now appears that they were wrong about both the time and place.
The esrf reveals how neanderthal teeth grew
Scientists from the United Kingdom, France and Italy have studied teeth from Neanderthals with X-rays from the European Synchrotron Radiation Facility (ESRF). They found that the dental development of Neanderthals is very similar to modern humans.
