Bex Caygill, University College London Today’s sloths might be known as slow, small animals, but their ancestors developed large body sizes at an amazing rate, according to an evolutionary reconstruction published September 10 in BMC Evolutionary Biology. The fast rate of change suggests that factors such as environmental conditions, or competition with other species, must have strongly favored the bigger sloths, before they died out. Scientists from UCL and University College Dublin...

Hallucigenia sparsa
2014-08-19 03:00:38

University of Cambridge One of the most bizarre-looking fossils ever found - a worm-like creature with legs, spikes and a head difficult to distinguish from its tail – has found its place in the evolutionary Tree of Life, definitively linking it with a group of modern animals for the first time. The animal, known as Hallucigenia due to its otherworldly appearance, had been considered an ‘evolutionary misfit’ as it was not clear how it related to modern animal groups. Researchers...

redOrbit Staff & Wire Reports - Your Universe Online Researchers have discovered nearly 50 bones belonging to a new species of winged reptile with a bizarre head crest comparable to a butterfly or a yacht sail, various media outlets reported earlier this week. The new creature, identified as Caiuajara dobruskii, lived in southern Brazil during the Cretaceous period. The remains were discovered in a pterosaur bone bed from an interdunal lake deposit from an ancient desert, and it...

April Flowers for redOrbit.com - Your Universe Online An international team of scientists has discovered what they believe to be the earliest example of social behavior in bird-hipped dinosaurs, along with a brand new species, in the Andes Mountains of Venezuela. The new species is described in the journal Proceedings of the Royal Society B: Biological Sciences. Until now, researchers have assumed this region was not home to dinosaurs because of the large deserts that surround it. The...

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...

April Flowers for redOrbit.com - Your Universe Online Approximately 520 million years ago, during the Lower Cambrian, the world's oldest known predator lived beneath the ocean's surface. An international team of scientists has identified what they call "an exquisitely preserved" brain in the fossil of a group of animals known as anomalocaridids, or "abnormal shrimp." The researchers were surprised to find that the brain of this predator was less complex than those found in fossils of some...

Long-Term Climate Factors Led Early Humans To Patchwork Evolution
2014-07-04 11:14:48

Brett Smith for redOrbit.com - Your Universe Online In the past, scientists concluded many of man’s defining qualities, such as legs made for walking upright and a large brain, evolved all at once. But according to a new study in the journal Science, shifts in climate caused these qualities to evolve separately. Based on analyses of fossil evidence, the study researchers said the shrinking of forests and expansion of savannas in East Africa led to walking upright, which freed our...

April Flowers for redOrbit.com - Your Universe Online Earth is full of evidence that dinosaurs once walked our planet. From fossil fuels to fossils themselves, the dinosaurs left their mark. These prehistoric creatures also left their footprints. Footprints can be found from Texas to China, tantalizing the imagination of the public and researchers alike. Such tracks have been found in an ancient seabed in China that, according to an international research team from the University of...

Int'l Research Team Names Most Primitive Species Of Flying Reptile
2014-04-24 14:57:10

Lawrence LeBlond for redOrbit.com - Your Universe Online Pterosaurs, an order of winged reptiles that were the earliest reptiles to evolve powered flight and had gone on to become the largest known flying creatures to have ever existed, are at the center of a new fossil study from a team of international researchers. Researchers from the University of South Florida, George Washington University and Chinese Academy of Sciences say they have found the most primitive pterodactyloid known,...

Mapinguari
2014-04-22 13:41:18

Mapinguari The mapinguari or mapinguary is an ape-like cryptid said to inhabit the Amazon rainforests of Brazil and Bolivia. It is also known as the Isnashi. Several attempts to find physical evidence that the creature exists have been conducted. Samples have been gathered, but when analyzed it was found to be from known animals and some of the castings of tracks were inconclusive. Native folklore has described the creature as having only one eye, long claws, backward feet, a...

Palaeovespa
2014-04-18 16:08:43

Palaeovespa is a genus of wasps that holds seven species, all of which are extinct. Two of the species were discovered in Baltic amber deposits from Europe dating back to the middle Eocene era, while the other five were found in Florissant Formation amber from the Priabonian stage era in Colorado in the United States. This genus, and four of its species, was first described in 1906 by Dr. Theodore Cockerell in the Bulletin of the Museum of Comparative Zoology. Cockerell described all but one...

Australopithecus africanus
2013-11-29 10:55:07

Australopithecus africanus was an early hominid, an australopithecine that lived between roughly 3.03 and 2.04 million years ago in the later Pliocene and early Pleistocene. Au. africanus was of slender build and was thought to have been a direct ancestor of modern humans. Fossil remains signify that Au. africanus was considerably more like modern humans that Au. afarensis, with a more human-like cranium permitting a larger brain and more humanoid facial features. This hominid has only been...

Thescelosaurus
2013-04-28 18:48:11

Thescelosaurus, meaning “godlike”, “wondrous”, or “marvelous” and “lizard” was a genus of small ornithopod dinosaur that appeared at the very end of the Late Cretaceous period in North America. It was a member of the last dinosaurian fauna before the Cretaceous-Paleogene extinction event around 65.5 million years ago. The completeness and preservation of many of its specimens illustrate that it might have preferred to live near streams. This bipedal ornithopod is known from...

Daspletosaurus
2013-04-28 18:27:18

Daspletosaurus, meaning “frightful lizard” is a genus of tyrannosaurid theropod dinosaur that resided in western North America between 77 and 74 million years ago, during the Late Cretaceous Period. Fossils of the only named species were found in Alberta, although other possible species from Alberta and Montana wait for description. Daspletosaurus is closely related to the much larger and more current Tyrannosaurus. Like most of the known tyrannosaurids, it was a multi-ton bipedal...
