Hannah Johnson, University of Bristol The ancestors of today's crocodiles colonized the seas during warm phases and became extinct during cold phases, according to a new Anglo-French study which establishes a link between marine crocodilian diversity and the evolution of sea temperature over a period of more than 140 million years. The research, led by Dr. Jeremy Martin from the Université de Lyon, France and formerly from the University of Bristol, UK is published this week in Nature...

Leaf-mining Insects Completely Disappeared With The Dinosaurs
2014-07-28 03:16:19

By A'ndrea Eluse Messer, Penn State After the asteroid impact at the end of the Cretaceous period that triggered the dinosaurs' extinction and ushered in the Paleocene, leaf-mining insects in the western United States completely disappeared. Only a million years later, at Mexican Hat, in southeastern Montana, fossil leaves show diverse leaf-mining traces from new insects that were not present during the Cretaceous, according to paleontologists. "Our results indicate both that...

Brett Smith for redOrbit.com - Your Universe Online The reexamination of a dinosaur skull found in Alaska has revealed that it may have belonged to a “smaller cousin” of Tyrannosaurs Rex – not a completely distinct species as originally believed. According to a report on the examination published on Wednesday in the journal PLoS ONE, the skull belonged to a lineage of theropods, or “beast feet,” dinosaurs that includes T. Rex. With most T. Rex fossils coming from temperate...

New Hell Creek, Montana Raptor Species Named, Described

Lawrence LeBlond for redOrbit.com - Your Universe Online A new species of dinosaur recently discovered in the Hell Creek Formation in Montana has been described as the youngest known dromaeosaurid and was a close cousin of the Velociraptor. The dinosaur, called Acheroraptor temertyorum, was approximately nine feet tall and weighed about 90 pounds when it was alive. The naming and description of this raptoran, which lived in what is now western North America some 66 to 67 million years...

Mapping The Dinosaur-Killing Yucatan Peninsula Asteroid Impact Site

April Flowers for redOrbit.com - Your Universe Online An asteroid or comet crashed into a shallow sea near what is now the Yucatan Peninsula of Mexico approximately 65 million years ago. A firestorm and global dust cloud resulted, causing the extinction of many land plants and large animals, including most of the dinosaurs. Researchers from the Monterey Bay Aquarium Research Institute (MBARI) presented evidence this week at a meeting of the American Geophysical Union (AGU) that remnants...

[ Watch the Video: Old Water Found In The New World ] redOrbit Staff & Wire Reports - Your Universe Online US Geological Survey (USGS) hydrologists drilling into the largest crater in the country have stumbled across an amazing discovery – the oldest body of seawater ever unearthed. The water, which according to Discovery News is at least 100 million years old, was found over one kilometer beneath Chesapeake Bay in Virginia. The seawater is believed to have come from the...

Mammal Diversity Faltered When Flowering Plants Arrived
2013-10-02 16:02:24

Brett Smith for redOrbit.com - Your Universe Online As mammals were trying to emerge from the shadows of dinosaurs 100 million years ago, there was a dramatic proliferation of flowering plant species. However, instead of early mammals benefiting from new food and shelter opportunities that would have been provided by the plants, they experienced a decline during the mid-Cretaceous. Using a morphological analysis, two researchers were able to provide these new insights about mammalian...

Ancient Crocodile Diversity

[ Watch the Video: Crocodiles Thrived During Prehistoric Times ] Brett Smith for redOrbit.com - Your Universe Online Ancient relatives of crocodiles had a wide range of habitats and ecosystems, with some species built like domestic dogs and others built for swimming through the open seas. Using a combination of morphological and biomechanical metrics to analyze these ancient crocodilians, a new study from researchers at the University of Bristol in the UK identified distinct trends...

Although scientists have known since the middle of the 19th century that the tropics are teeming with species while the poles harbor relatively few, the origin of the most dramatic and pervasive biodiversity on Earth has never been clear. New research sheds light on how that pattern came about. Furthermore, it confirms that the tropics have been and continue to be the Earth's engine of biodiversity. By examining marine bivalves (two-shelled mollusks including scallops, cockles and...

Ichthyosaur Fossil Indicates Dolphin-Like Dinos Survived Into Jurassic

Credit: Rémih/Wikipedia (CC BY-SA 3.0) Tenontosaurus, meaning “sinew lizard”, is a genus of medium to large sized ornithopod dinosaur. The genus is known from the late Aptian to Albian ages of the middle Cretaceious period sediments of western North America, dating roughly between 115 to 108 million years ago. It was formerly thought to be a ‘hypsilophodont’, but since Hypsilophodontia is no...

Sauroposeidon, meaning “earthquake god lizard,” is a genus of sauropods dinosaur from the Aptian and Albian ages of the Early Cretaceous Period (110 million years ago). It was discovered in the southeast region of Atoka County, Oklahoma, not far from the border of Texas, in a claystone outcrop. The fossils were initially misidentified as pieces of petrified wood when they were found in 1994. A more detailed analysis in 1999 revealed they were truly dinosaurian bones. They were formally...

Qiaowanlong is a genus of sauropod dinosaur from the Albian stage of the Early Cretaceous Period (100 million years ago). It was discovered in the Yujinzi Basin of Gansu, China in 2007. It came from the geological formation called the Xinminpu Group. Qiaowanlong is known from articulated cervical (neck) vertebrae and a right pelvic girdle, as well as several unidentified bone fragments. It was the first brachiosaurid to have been found from China. Qiaowanlong is estimated to have been...

Qantassaurus is a genus of ornithopod dinosaur from the late Aptian to early Albian age of the Early Cretaceous Period (115 million years ago). It lived in Australia when the continent was still south of the Antarctic Circle, and was still part of the supercontinent Gondwana. Qantassaurus was discovered in 1996 during the third annual field season of the Dinosaur Dreaming Project, a dig jointly run by Monash University and Museum Victoria. It was found in the intertidal site known as Flat...

Santanaraptor, meaning "Santana Formation thief", is a genus of theropod dinosaur from the Albian or Aptian stage of the Early Cretaceous Period (108 million years ago). It lived in what is now South America. When first discovered, Santanaraptor was thought to be a maniraptoran theropod. However, it is now thought to be a primitive coelurosaur based on features present on the femur. The type species, S. placidus, was first described by Kellner in 1999. The species name refers to Placido...
