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...

Brett Smith for redOrbit.com - Your Universe Online Several large marine animals have evolved from fearsome predators to become gentle giants that use filtering appendages to ingest food, and new research from a team of European researchers has revealed a similar evolution in a group of predators that roamed the oceans 520 million years ago during the Early Cambrian. According to the team’s report in the journal Nature, an early arthropod called Tamisiocaris borealis used large curly...

A failed Saharan Atlantic Ocean rift zone Break-up of the supercontinent Gondwana about 130 Million years ago could have lead to a completely different shape of the African and South American continent with an ocean south of today's Sahara desert, as geoscientists from the University of Sydney and the GFZ German Research Centre for Geosciences have shown through the use of sophisticated plate tectonic and three-dimensional numerical modelling. The study highlights the importance of rift...

SEATTLE, Feb. 12, 2014 /PRNewswire-USNewswire/ -- A spectacular new discovery of Cambrian animal fossils has intensified a source of doubt that troubled Darwin about his theory, according to scientific researchers at Discovery Institute. About 26 miles from the famous Walcott quarry, a new exposure of Burgess Shale fossils has come to light. Called the Marble Canyon quarry, this fossil assemblage, reported in Scientific American, Nature Communications, and elsewhere, appears to be...

Canada's Kootenay National Park Home To Epic Burgess Shale Site
2014-02-12 06:38:48

April Flowers for redOrbit.com - Your Universe Online The 505-million-year-old Burgess Shale found in Yoho National Park in British Columbia is home to some of the world's earliest animals, including a very primitive human relative. It is also considered to be one of the world's most important fossil sites. More than one hundred years after its discovery, a new Burgess Shale fossil site has been discovered 26 miles away in Kootenay National Park. According to Pomona College geologist...

No Single Factor Behind Cambrian Explosion Of Animal Life
2013-09-20 07:58:01

April Flowers for redOrbit.com - Your Universe Online A new study from the UK reveals that the explosion of animal life on Earth that occurred around 520 million years ago was the result of a combination of interlinked factors, rather than a single underlying cause. Over the past few decades, dozens of individual theories have been put forth for the rapid diversification of animal species in the early Cambrian period. The new study, published in Science, suggests a more holistic...

Earliest Known Scorpion Fossil Discovered In South Africa
2013-09-03 12:41:53

Lee Rannals for redOrbit.com - Your Universe Online Scientists publishing a study in the journal African Invertebrate say they have discovered a 350-million-year-old fossilized scorpion. The specimen, discovered in rocks from the Devonian Witteberg Group near Grahamstown, is a new species of scorpion called Gondwanascorpio emzantsiensis. Dr Robert Gess, from the Evolutionary Studies Institute at Wits University, discovered the specimen, which is said to be the oldest known land-living...

Fossils Show Anatomy Of Ancient Fuxianhuiid Arthropod
2013-02-28 09:06:34

April Flowers for redOrbit.com - Your Universe Online An international group of scientists led by researchers at the University of Cambridge has made an extraordinary find in South China. For the first time, scientists are able to see through the head of the "fuxianhuiid" arthropod, revealing one of the earliest evolutionary examples of limbs used for feeding along with the oldest nervous system to stretch beyond the head in fossil record. Prior to this find, heads covered by a...

Ancient Fossilized Sea Creatures Contain Oldest Biomolecules Taken Directly From A Fossil
2013-02-19 13:45:53

The Ohio State University Though scientists have long believed that complex organic molecules couldn´t survive fossilization, some 350-million-year-old remains of aquatic sea creatures uncovered in Ohio, Indiana, and Iowa have challenged that assumption. The spindly animals with feathery arms–called crinoids, but better known today by the plant-like name “sea lily”–appear to have been buried alive in storms during the Carboniferous Period, when North America...

Bennett’s feather star, Oxycomanthus bennetti
2013-08-04 08:28:29

Bennett's feather star is a suspension feeder that grows to be about 1 foot with 31-120 arms extending upward from the body. The star catches the food, usually phytoplankton and zooplankton, with tubed feet located on the outside of the arms. Yellow, Brown, Green and Purple are the most common colors for the Bennett's feather star. The star will remain attached to the seabed by a stalk until it reaches maturity and then becomes free-living by breaking off from the stalk. The Bennett's...

Variable bushy feather star, Comaster Schlegelii
2013-05-18 06:46:30

The Variable bushy feather star is commonly found concealed on shallow water reefs in the western Pacific Ocean. The parts that will be most often seen are the fern-like arms. The arms start at the base with five rays then begin to divide from there. The arms are flexible due to the multiple calcium filled joints, also called ossicle; therefore if needed these arms could coil up and provide protection to the main body. Interestingly, if one arm should fall off, or perhaps pulled off, then two...

Noble feather star, Comaster nobilis
2013-05-18 06:36:19

The noble feather star (also known as the yellow feather star) reaches up to 15.75 inches in diameter with a cup-shaped body. There can be 35-40 arms extending out of the central part of the body. The arms are primarily yellow with the underside having a variation to include black, green, or white. The noble feather star feeds on food debris, phytoplankton and zooplankton. Phytoplankton and zooplankton are microscopic organisms that are present mainly in the layer of the oceans that is...

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...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
