Tracks of a Running Bipedal Baby Brontosaur? Staff at the Morrison Natural History Museum have again discovered infant dinosaur footprints in the foothills west of Denver, near the town of Morrison. Dating from the Late Jurassic, some 148 million years ago, these tracks were made before the Rocky Mountains rose, when Morrison was a broad savanna full of dinosaurs. The fossil tracks represent infant sauropods, according to discoverer Matthew Mossbrucker, the museum's director. Sauropods are...

As news of a remarkably well-preserved cache of dinosaur bones was being heralded in media outlets around the world, the U.S. Bureau of Land Management paleontologist who had announced the find was taking a breath and urging others to do the same. No new species were turned up at the 3-month-old site, although a lot of digging is yet to be done. It is within the same Utah/ Colorado border region where at least two previously unheard-of dinosaur species were discovered during the past 10...

By Brian Maffly, The Salt Lake Tribune Jun. 23--HANKSVILLE -- An ancient river, which probably dried up one season, only to swirl and surge with monsoonal violence the next, once braided through this area just southeast of what is now Utah's San Rafael Swell. The river must have slowed here, shedding its load of sand, silt, gravel, trees, clams and dinosaur carcasses, dismembered chunks of big lizards that lived 145 to 150 million years ago. Locals had known this area as a boneyard...

A team of Illinois scientists looking for fossils of big dinosaurs in Utah's Morrison limestone struck pay dirt last month, opening the possibility of a major dinosaur quarry outside Hanksville. In recent weeks, the group, representing the Burpee Museum of Natural History, uncovered "a logjam" of 148-million-year remains of as many as six dinosaur species and massive coniferous trees so well preserved you can feel their bark and read their tree rings. And that's just scratching the surface,...

Othnielosaurus is a genus of ornithiscian dinosaur from the Late Jurassic Period (155 to 148 million years ago). It lived in what is now the western United States. It was formerly assigned to the genus Laosaurus. It is now named in honor of famed paleontologist Othniel Charles Marsh. This genus was coined to contain the fossils formerly included in Othnielia, which is based on remains that may be too sparse to hold a name. Decades have been spent on research to untangle the taxonomy left...

Elaphrosaurus or "lightweight lizard" is a genus of carnivorous dinosaur from the Late Jurassic Period. It lived in what is now the Kimmeridgian state of Tanzania. Its skeleton was found in the Tendaguru Beds of Tanzania. A related animal was found in the Morrison Formation of the western United States. Most fossils of theropods found have only been fragments, until the discovery of a single nearly complete skeleton of Elaphrosaurus. It did not contain the skull. Elaphrosaurus was about...
