Fossil antelopes shed new light on today's sub-Saharan mammalswww.sciencedaily.comModern-day Africa south of the Sahara is home to a unique variety of mammals, a great number of which are not found anywhere else in the world. New fossil antelope discoveries have provided a glimpse into the biogeographic configuration of Africa over the last seven million years.
Vietnam's biodiversity has deep roots in Earth's pastwww.sciencedaily.comSoutheast Asia is a global biodiversity hotspot with a very high number of animal and plant species, many of which are only found there. Despite its highly endangered terrestrial and freshwater ecosystems, Vietnam makes a significant contribution to this biological diversity. Scientists now demonstr
ScienceDaily (Feb. 7, 2011) - Synchrotron X-ray investigation of a fossilized snake with legs is helping scientists better understand how in the course of evolution snakes have lost their legs, and whether they evolved from terrestrial lizards or from reptiles living in the oceans. New 3-D X-ray images reveal the internal architecture of an ancient snake's leg bones strongly resembles that of modern terrestrial lizard legs - (Image Credit: A. Houssaye)
news.nationalgeographic.com (February 3, 2011) - There's a new titleholder for biggest bear ever found-an ancient South American giant short-faced bear that weighed up to 3,500 pounds - "There's nothing else that even comes close.", expert says - South American giant short-faced bear vs. typical human - Image credit: Blaine Schubert.
ScienceDaily (Feb. 3, 2011) - Researchers have discovered the 100 million-year-old ancestor of a group of large, carnivorous, cricket-like insects that still live today in southern Asia, northern Indochina and Africa. The new find corrects the mistaken classification of another fossil of this type and reveals that the genus has undergone very little evolutionary change since the Early Cretaceous Period - (Photo Credit: Hwaja Goetz)
ScienceDaily (Feb. 1, 2011) - Triceratops and Torosaurus have long been considered the kings of the horned dinosaurs. But a new discovery traces the giants' family tree further back in time, when a newly discovered species called Titanoceratops appears to have reigned long before its more well-known descendants, making it the earliest known member of its family. The skull on the left is the Titanoceratops skull, the missing parts of which were reconstructed to look like a Pentaceratops. The illustration on the right shows the missing parts of the frill (shaded). (Credit: Image courtesy of Yale University).
ScienceDaily (Jan. 28, 2011) - Researchers have determined that a fossilized dinosaur bone found in New Mexico confounds the long established paradigm that the age of dinosaurs ended between 65.5 and 66 million years ago - Image: (Plate 71-A in U.S. Geological Survey / Bauer, C.M. 251)
ScienceDaily (Jan. 26, 2011) - Tyrannosaurus rex hunted like a lion, rather than regularly scavenging like a hyena, new research reveals. The findings end a long-running debate about the hunting behavior of this awesome predator - Artist's rendition of Tyrannosaurus rex. (Credit: iStockphoto)
nationalgeographic.com - January 15, 2011 - The giant extinct invertebrate Arthropleura resembled some modern millipedes, but could grow to be more than one-and-a-half feet wide, and may sometimes have been more than six feet long.

ScienceDaily (Jan. 21, 2011) -The mystery of how an abundance of fossils have been marvelously preserved for nearly half a billion years in a remote region of Africa has been solved by a team of geologists - This is a Eurypterid (sea scorpion) from the Soom Shale, South Africa. This fossil is approximately 440 million years old. It is so well-preserved that you can see its muscle blocks, gills and paddles that it used for swimming. (Credit: University of Leicester)
ScienceDaily (Jan. 20, 2011) -Killed and preserved with her egg, a fossil of a flying reptile shows for the first time how hips and crests can be used to sex pterodactyls - Photo: a close up of the egg preserved together with Mrs. T, a female Darwinopterus - (Credit: Lü Junchang, Institute of Geology, Beijing).
ScienceDaily (Jan. 13, 2011) - A team of paleontologists and geologists from Argentina and the United States have discovered a lanky dinosaur that roamed South America in search of prey as the age of dinosaurs began, approximately 230 million years ago. Sporting a long neck and tail and weighing only 10 to 15 pounds, the new dinsaur has been named Eodromaeus, the "dawn runner." - (Credit: Illustration by Todd Marshall)
Discovery News - Jan 6, 2011 - These creatures, once the most abundant marine animals on Earth, likely went extinct because of a food shortage at the end od CretaceousPeriod. The last meal of a Dinosaur-Era ammonite was found still lodged in the marine animal's mouth. High-powered X-rays reveal that ammonites had jaws and a toothed tongue-like structure. Image: S. Thurston.
blogs.smithsonianmag.com - January 4, 2011 - Many unknown dinosaurs await discovery in rock formations all over the world, but some new species are hiding in plain sight. A close up of the Sam Noble museum specimen, just re-named Titanoceratops. Image from Flickr user cosmicautumn.
ScienceDaily (Jan. 6, 2011) - Researchers report that the transition from a generally oxygen-rich ocean during the Cambrian to the fully oxygenated ocean we have today was not a simple turn of the switch, as has been widely accepted. Their work shows the ocean fluctuated between oxygenation states 499 million years ago. Image: Researcher Benjamin Gill near the top of a stratigraphic section at Lawsons Cove, Utah.

Recentemente la comunità scientifica internazionale ha riconosciuto la validità del genere Catriceras. Proposto dal prof. Federico Venturi nel 1978, sono passati oramai 30 anni. Durante tutti questi anni il lavoro ha subito numerose critiche da parte della comunità scientifica ma la caparbietà e la passione dello studioso italiano sono state alla fine premiate - Photo Gruppo Umbro Mineralogico Paleontologico

ScienceDaily (Jan. 5, 2011) -Paleontologists have discovered that Xenicibis, a member of the ibis family that lived about ten thousand years ago and was found only in Jamaica, most likely used its specialized wings like a flail, swinging its upper arm and striking its enemies with its thick hand bones - Credit: Science Daily - Photo Credit: Nicholas Longrich/Yale University

www.examiner.com - January 28th, 2011 - Paleontologists and researchers reported the discovery of a new Sauropod dinosaur at the January Public Library of Science site. The new specimen, Leonerasaurus taquetrensis, was found in the Las Leoneras Formation of Central Patagonia (Argentina) is used by the researchers to demonstrate that the characteristic Sauropod body plan evolved gradually, with a stepwise pattern of character appearance - Photo: www.plosone.org

It's the biggest collection of dinosaur footprints in the world. How did these 68 million-year-old prints wind up here? (Photo by Leslie Middlemass)
