Unique Dinosaur Roamed The Desert Of Supercontinent Pangea
2013-06-25 09:03:28

April Flowers for redOrbit.com - Your Universe Online Pangaea, a single supercontinent existing from 300-200 million years ago, dominated the Earth during the Permian era with animal and plant life dispersed broadly across the land. This disbursement is documented by identical fossil species found on multiple modern continents. A new study, from the Society of Vertebrate Paleontology, supports the idea that Pangaea had an isolated desert at the center of the supercontinent with unique...

Embryonic Subduction Zone Could One Day Unite Continents
2013-06-18 05:03:08

redOrbit Staff & Wire Reports - Your Universe Online The activation of a passive plate boundary in the Atlantic Ocean could ultimately result in continental Europe moving closer to the US, according to new research appearing in the journal Geology. In the study, geologists at Monash University in Melbourne, Australia report they have uncovered the first direct evidence that a subduction zone forming off the coast of Portugal will begin a cycle which results in the closing of the...

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...

Four New Studies Show Early Humans Had A Diet Rich In Grass
2013-06-04 11:43:40

Lawrence LeBlond for redOrbit.com - Your Universe Online Four new studies have taken a new look at the diets of our ancestors and have found their behavior was a “game changer” for early humans some 3.5 million years ago. An ape-like diet that included grasses and sedges paved the way for a diet rich in grains, meats and dairy from grazing animals. In the first of the four studies, researchers from the University of Colorado Boulder conducted high-tech tests on tooth enamel...

Atlantis Found In Brazil Via Discovery Of Ancient Granite Rock

Lawrence LeBlond for redOrbit.com - Your Universe Online First mentioned in two dialogues (Timaeus and Critias) by Plato in 360 BC, the legendary island of Atlantis has long been sought by historians, archaeologists, and explorers alike. Said to have originally existed between South America and Africa, this sunken island has been searched for in no less than dozens of locations worldwide, from Bimini to the Black Sea. In a new twist, a team of scientists from Brazil and Japan say they...

Ancient Hominid Study Reveals Early Similarities Between Humans And Apes
2013-04-12 09:07:49

Lawrence LeBlond for redOrbit.com - Your Universe Online One of the largest studies on some of the most complete remains of early human ancestors has culminated in a comprehensive look into how an early hominid (Australopithecus sediba) moved and chewed. The study, collaborated on by an international team of scientists and published in six papers in the journal Science, details not only early traits but also describes notable features that set it apart from modern humans. The research...

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...

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...

Geologic Clock With Events And Periods

The Neoproterozoic is the third of three subdivisions of the Proterozoic Eon (occurring from 1 billion years ago to 542 million years ago). This terminal era of the Proterozoic is itself divided into three sub-periods called the Tonian, Cryogenian, and Ediacaran Periods. The most severe glaciation known in the geologic record occurred during the Cryogenian Period, when ice sheets reached the equator and formed a possible “Snowball Earth.” And the earliest fossils of multi-cellular life...

The Paleoproterozoic is the first of three subdivisions of the Proterozoic Eon (occurring from 2.5 billion to 1.6 billion years ago (Ga). This period is marked by the first stabilization of the continents, and also when cyanobacteria--a type of bacteria that uses biochemical processes of photosynthesis to produce oxygen--evolved. Experts have found paleontological evidence that during at least part of the Paleoproterozoic era, about 1.8 Ga, the earth year was about 450 days long, with days...

toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
