Fossil And Molecular Evidence Important For Studying Evolution
2013-08-10 05:19:24

redOrbit Staff & Wire Reports - Your Universe Online The fossils of microscopic aquatic creatures, whose shells resemble grains of sand to the naked eye, could help shed new light on the process of evolution, according to new research published Friday in the journal Methods in Ecology & Evolution. As part of their research, University of Southampton evolutionary ecologist Dr. Thomas Ezard and his colleagues are analyzing the remains of the one-millimeter large planktonic...

Land Life Earlier Than Thought
2013-07-22 14:37:42

Brett Smith for redOrbit.com - Your Universe Online Conventional theories have placed life on land for the last 500 million years, but a new study from a team of American and Australian researchers might push that back to 2.2 billion years. To support their claim, the scientists presented evidence in the form of tiny newly discovered fossils the size of a match head called Diskagma buttonii that were discovered in ancient soil samples. "They certainly were...

Using Synchrotron X-rays To Put Flesh On The Bones Of Ancient Fish
2013-06-13 15:53:46

European Synchrotron Radiation Facility Swedish, Australian and French researchers present for the first time miraculously preserved musculature of 380 million year old armored fish discovered in north-west Australia. This research will help scientists to better understand how neck and abdominal muscles evolved during the transition from jawless to jawed vertebrates. The scientific paper describing the discovery is published today in the journal Science. The team of scientists who...

Efforts to restore sturgeon in the Great Lakes region have received a lot of attention in recent years, and many of the news stories note that the prehistoric-looking fish are "living fossils" virtually unchanged for millions of years. But a new study by University of Michigan researchers and their colleagues reveals that in at least one measure of evolutionary change–changes in body size over time–sturgeon have been one of the fastest-evolving fish on the planet. "Sturgeon...

Ancient Stromatolites May Have Been Edged Out By Foraminifera
2013-05-29 05:47:20

April Flowers for redOrbit.com - Your Universe Online Stromatolites, “layered rocks” made of calcium carbonate, were the earliest visible manifestation of life on Earth. A team of researchers, including scientists from the Woods Hole Oceanographic Institution (WHOI); Massachusetts Institute of Technology (MIT); the University of Connecticut; Harvard Medical School; and Beth Israel Deaconess Medical Center, suggest that the disappearance of stromatolites may have been driven by...

Oldest Evidence Of Split Between Monkeys And Apes Discovered
2013-05-16 14:39:00

Brett Smith for redOrbit.com - Your Universe Online Two fossil discoveries have revealed new details about the evolutionary divergence of apes and Old World monkeys, such as macaques and baboons, according to a report published in the journal Nature. The two primate fossils are from the late Oligocene epoch, about 25 million years ago, which is considerably older than previously discovered fossils for either group. The study authors conclude that the two groups of primates were already...

Ancient Fish Fossils Give Insight Into Evolutionary History Of Gobioid Order
2013-05-16 13:51:46

LMU Fish fossils that are about 23 million years old give unprecedented insight into the evolutionary history of the gobioid order, one of the most species-rich groups among the modern bony fishes. Researchers led by paleontologist Professor Bettina Reichenbacher from the Division of Paleontology and Geobiology at LMU´s Department of Earth and Environmental Sciences have completed a comprehensive analysis of fish fossils which they assign to the group of bony fishes that includes...

Ichthyosaur Fossil Indicates Dolphin-Like Dinos Survived Into Jurassic
2013-05-15 14:43:09

Brett Smith for redOrbit.com - Your Universe Online A fossil previously used as a stepping stone for mules has deepened the mystery surrounding the evolution of ichthyosaurs, dolphin-like marine reptiles that were contemporaries of the dinosaurs. According to a newly published report in the journal“¯Biology Letters,“¯an analysis of the fossil, dubbed Malawania anachronus, has suggested that ichthyosaurs survived well into the...

Ancient Cave Of Death Explained
2013-05-02 12:11:56

Brett Smith for redOrbit.com - Your Universe Online For over 20 years, archeologists have been recovering an unusually high number of large carnivore fossils from a cave near Madrid, Spain. According to a new report in the open access journal PLOS ONE, the saber-toothed cat, hyena and red panda“¯ancestor remains found at the site are the result of these animals purposely wandering into the cave and then becoming trapped under mysterious conditions between 9 and 10 million years...

Clue To Smell Of Ancient Earth Given By Fossils
2013-04-29 15:23:27

University of Oxford Tiny 1,900 million-year-old fossils from rocks around Lake Superior, Canada, give the first ever snapshot of organisms eating each other and suggest what the ancient Earth would have smelled like. The fossils, preserved in Gunflint chert, capture ancient microbes in the act of feasting on a cyanobacterium-like fossil called Gunflintia — with the perforated sheaths of Gunflintia being the discarded leftovers of this early meal. A team, led by Dr David Wacey...

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...
