PERTH, Australia (AP) - Australia on Friday handed over to the Chinese government 10,000 fossils that had been illegally exported from China, including dinosaur eggs, ancient turtles and a saber-toothed cat, an official said. Australian officials seized the fossils after receiving an official request from Beijing in 2003, Environment and Heritage Minister Ian Campbell said in a statement. A joint operation between Australian police and customs netted an "extraordinary" range of pieces,...

South America has the most biodiversity of any major region today and according to an international team of researchers, that biodiversity began at least 52 million years ago. "What defines terrestrial ecology is plant insect interactions," says Dr. Peter Wilf, assistant professor of geosciences and the John T. Ryan Jr. Faculty Fellow. "But there is very little information about the history of insects eating plants in South America, despite the tremendous number of plant and animal species...

BERKELEY, CA -- A detailed and extensive new analysis of the fossil records of marine animals over the past 542 million years has yielded a stunning surprise. Biodiversity appears to rise and fall in mysterious cycles of 62 million years for which science has no satisfactory explanation. The analysis, performed by researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley, has withstood thorough...

Did life shape the early Earth, or did the early Earth shape life? The choice may be a false dichotomy, but living without light, water or oxygen gave the earliest microbes a limited menu to order their lives around. Astrobiology Magazine -- A geomicrobiologist at Washington University in St. Louis has proposed that evolution is the primary driving force in the early Earth's development rather than physical processes, such as plate tectonics. Carrine Blank, Ph.D., Washington University...

Atrypa
2014-01-12 00:00:00

Atrypa (lampshell) is an extinct genus of brachiopod from the Late Ordovician stage (444 million years ago) to the Carboniferous stage (318 mya). It occurs abundantly as fossils in marine rocks. Fossils have been found on all continents except Antarctica. This animal has distinctive concentric growth lines and is unusual in that in some Devonian beds there are numerous remains of the pedicle (foot) valve, but very few of the brachial (upper) valve -- scientists speculate that strong ocean...

Seitaad, derived from a Navajo legend of a san monster with the same name -- "Seit'aad," is a genus of prosauropod dinosaur from the Early Jurassic Period. The type species, S. ruessi, was described in 2010 based on fossils recovered from the Navajo Sandstone Formation in southern Utah. It is known from a nearly complete fossil that appears to have been entombed by the collapse of a sand dune about 185 million years ago. Based on the fossil, the dinosaur would have been 10 to 15 feet long...
