artists reconstruction of Tamisiocaris borealis
2014-03-27 09:19:17

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...

Parental Care From 450 Million Years Ago
2014-03-14 11:27:40

University of Leicester A portrait of prehistoric parenthood captured deep in the fossil record has been uncovered by an international team of scientists led by University of Leicester geologist Professor David Siveter. The 'nursery in the sea' has revealed a species new to science – with specimens preserved incubating their eggs together with probable hatched individuals. As a result, the team has named the new species Luprisca incuba after Lucina, goddess of childbirth, and alluding...

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...

Bigger Really Was Better For Early Prehistoric Life

[ Watch the Video: The Evolution of the World’s Oldest Fossil Communities ] University of Toronto A NASA research group featuring University of Toronto Mississauga professor Marc Laflamme has helped to explain why some prehistoric organisms evolved into larger animals. Laflamme, an assistant professor with the Department of Chemical and Physical Sciences, and his colleagues at the Massachusetts Institute of Technology Node of NASA's Astrobiology Institute suggest that height...

New Fish Fossil Reveals How Fins May Have Become Hind Limbs
2014-01-14 06:11:22

[ Watch the video: Tiktaalik roseae fossils reveal evolution of hind limbs ] April Flowers for redOrbit.com - Your Universe Online The evolution of hind legs actually began as enhanced hind fins, according to the newly discovered, well-preserved pelvis and a partial pelvic fin from Tiktaalik roseae—a 375 million-year old transitional species between fish and the first legged animals. The findings, published in Proceedings of the National Academy of Sciences (PNAS), challenge the...

Important Discovery Of Marine Fossils In Linxi Formation, China
2013-12-07 08:52:40

Science China Press In a recent study, large numbers of bryozoan and other typical marine fossils were discovered for the first time in the thick limestone layers and lenses of the upper part of the Linxi Formation of the Guandi section, Linxi County, eastern Inner Mongolia. These marine fossils provide the first evidence for the Xingmeng area being in a marine or mainly marine environment at the end of the later part of the late Permian. This paper, entitled "Discovery of marine...

Oxygen Levels Prior To The Cambrian Explosion May Have Been Enough For Life
2013-10-19 05:00:29

redOrbit Staff & Wire Reports - Your Universe Online An international team of researchers has discovered that the Earth’s oxygen content 2.1 billion years ago was the same as it was during the so-called Cambrian explosion that occurred approximately 542 years ago and resulted in the appearance of most major animal phyla. Given the fact that oxygen and the development of advanced life are inextricably linked, this led the study authors to ponder the sudden emergence of living...

Researchers Have Developed New Quantitative Method Of Identifying Pollen Grains
2013-10-07 13:10:51

University of Illinois Since the invention of the earliest light microscopes, the classification and identification of pollen and spores has been a highly subjective venture for those who use these tiny particles to study vegetation in their field, palynology. However, according to the lead author of the study, Luke Mander, a former postdoctoral researcher in the laboratory of Illinois professor of plant biology Surangi Punyasena, the limitations imposed by these descriptive rather than...

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...

Paleontology
2014-01-12 00:00:00

Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...

Paleozoology
2013-09-30 13:34:57

Paleozoology, also spelled Palaeozoology, is a branch of many other sciences including zoology and paleontology that focuses on recovering cellular matter from animal remains that are large enough to be seen without the help of a microscope, known as macrofossils. This study is primarily used in the context of archeology and geology and aids in recreating ancient ecosystems and prehistoric environments. Paleozoologists study the tissues of many types of animals including sharks, echinoderms,...

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...
