 | An 80-million-year-old dinosaur fossil unearthed in the Gobi Desert of Mongolia demonstrates that miniaturization, long thought to be a hallmark of bird origins and a necessary precursor of flight, occurred progressively in primitive dinosaurs. ...> Full Article |
 | With the eye of an electrical engineer, Nels Peterson is hoping to bring a new, high-tech tool to the field excavation of dinosaurs, a labor of picks, shovels and brushes that has changed little over the past 100 years. ...> Full Article |
Scientists at the University of Sheffield, collaborating with colleagues at the Universities of Portsmouth and Reading, have taken a step back in time and provided a new insight into the lifestyle of a prehistoric flying reptile.

 | Fossils discovered in the oft-painted arroyos of northern New Mexico show for the first time that dinosaurs and their non-dinosaur ancestors lived side by side for tens of millions of years, disproving the notion that dinosaurs rapidly replaced their supposedly outmoded predecessors. ...> Full Article |
 | A dinosaur bone bed in southwest Edmonton that served as a feeding area for the direct ancestor of Tyrannosaurus rex has revealed that two dinosaurs, thought to have lived in different eras, actually lived at the same time. ...> Full Article |
 | Teaming up with local scholars, CAS paleontologists recently discovered a giant bird-like dinosaur from Erlian, one of the world-famous graveyards of "terrible lizards" in Inner Mongolia. ...> Full Article |

 | The fossilized bones of a previously unknown, 220 million-year-old long-necked, gliding reptile may remain forever embedded in stone, but thanks to an industrial-size CT scanner at Penn State's Center for Quantitative Imaging, the bone structure and behavior of these small creatures are now known. ...> Full Article |
 | The peculiar pose of many fossilized dinosaurs, with wide-open mouth, head thrown back and recurved tail, likely resulted from the agonized death throes typical of brain damage and asphyxiation, according to two paleontologists. ...> Full Article |
 | What did dinosaurs hear? Probably a lot of low frequency sounds, like the heavy footsteps of another dinosaur, if University of Maryland professor Robert Dooling and his colleagues are right. What they likely couldn't hear were the high pitched sounds that birds make. ...> Full Article |
Researchers at the Morrison Natural History Museum have discovered two rare hatchling dinosaur footprints in the foothills west of Denver, near the town of Morrison.

 | An extraordinary underwater trackway with 12 consecutive prints provides the most compelling evidence to-date that some dinosaurs were swimmers. The 15-meter-long trackway, located in La Virgen del Campo track site in Spain's Cameros Basin, contains the first long and continuous record of swimming by a non-avian therapod dinosaur. ...> Full Article |
 | New evidence may help explain the brute strength of the tyrannosaurid, says a University of Alberta researcher whose finding demonstrates how a fused nasal bone helped turn the animal into a "zoological superweapon." ...> Full Article |

A new study appearing in the May issue of The Journal of Geology provides fascinating insight into the factors geologists must account for when examining dinosaur tracks. The authors studied a range of larger tracks from the family of dinosaurs that includes the T. Rex and the tridactyl, and provide a guide for interpreting the effects of many different types of erosion on these invaluable impressions.

Scientists have long thought that the mass extinction of the dinosaurs around 65 millions years ago opened the door for modern mammal species to proliferate. But an international team of scientists has created a mammoth record of evolutionary timing, showing that the origins and diversification of existing mammal species - including human ancestors - don’t synch with the demise of the dinosaurs.
