Exceptionally Well Preserved Insect Fossils Discovered In The Rhône Valley
2014-09-02 03:03:03

PeerJ First fossil insect discoveries in this area comprise the oldest water treader and traces of activities in sediment and on plants In Bavaria, the Tithonian Konservat-Lagerstätte of lithographic limestone is well known as a result of numerous discoveries of emblematic fossils from that area (for example, Archaeopteryx). Now, for the first time, researchers have found fossil insects in the French equivalent of these outcrops - discoveries which include a new species representing...

Polypterus senegalus
2014-09-01 04:00:02

Cynthia Lee, McGill University About 400 million years ago a group of fish began exploring land and evolved into tetrapods – today's amphibians, reptiles, birds, and mammals. But just how these ancient fish used their fishy bodies and fins in a terrestrial environment and what evolutionary processes were at play remain scientific mysteries. Researchers at McGill University published in the journal Nature, turned to a living fish, called Polypterus, to help show what might have...

Fossil of Haootia quadriformis
2014-08-28 03:00:26

Sarah Collins, University of Cambridge A new fossil discovery identifies the earliest evidence for animals with muscles. An unusual new fossil discovery of one of the earliest animals on earth may also provide the oldest evidence of muscle tissue – the bundles of cells that make movement in animals possible. The fossil, dating from 560 million years ago, was discovered in Newfoundland, Canada. On the basis of its four-fold symmetry, morphological characteristics, and what appear to...

paleontological reconstruction of rangeomorph fronds
2014-08-13 04:00:43

University of Cambridge New three-dimensional reconstructions show how some of the earliest animals on Earth developed, and provide some answers as to why they went extinct. A bizarre group of uniquely shaped organisms known as rangeomorphs may have been some of the earliest animals to appear on Earth, uniquely suited to ocean conditions 575 million years ago. A new model devised by researchers at the University of Cambridge has resolved many of the mysteries around the structure,...

Late Meroitic grave
2014-07-18 04:00:15

University of York An international team of researchers has found new evidence that our prehistoric ancestors had a detailed understanding of plants long before the development of agriculture. By extracting chemical compounds and microfossils from dental calculus (calcified dental plaque) from ancient teeth, the researchers were able to provide an entirely new perspective on our ancestors’ diets. Their research suggests that purple nut sedge (Cyperus rotundus) – today regarded as a...

Lyrarapax unguispinus

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...

reconstruction of the early Eocene
2014-07-09 09:33:31

Gerard LeBlond for redOrbit.com - Your Universe Online The Silvacola acares is a tiny hedgehog species that lived roughly 52-million-years ago, during the Eocene Epoch. Its fossil remains were recently identified by a University of Colorado Boulder-led team working in British Columbia. Along with the tiny hedgehog, the fossils of a tapir-like animal were also discovered. A paper on the discovery of these two ancient mammals is being published today in the Journal of Vertebrate...

AGI The Society for Sedimentary Geology (SEPM) announces an unusual paper in their journal PALAIOS that combines ‘forensic’ paleontology and archeology to identify origins of the millstones commonly used in the 1800’s. While all millstones were used similarly, millstones quarried in France were more highly valued than similar stones quarried in Ohio, USA. Over four years the scientific team located millstones by visiting historical localities in Ohio, then studied them and...

New Fossil Organism Discovered By Paleontologists
2014-05-12 03:23:48

By Iqbal Pittalwala, University of California - Riverside Likely related to our ancestors, 'Plexus ricei' was much like a tapeworm or modern flatworm, say UC Riverside researchers Scientists at the University of California, Riverside have discovered a fossil of a newly discovered organism from the "Ediacara Biota" — a group of organisms that occurred in the Ediacaran period of geologic time. Named Plexus ricei and resembling a curving tube, the organism resided on the Ediacaran...

Researchers Find Rare Fossilized Embryos More Than 500 Million Years Old
2014-04-11 13:06:23

Jeff Sossamon, University of Missouri The Cambrian Period is a time when most phyla of marine invertebrates first appeared in the fossil record. Also dubbed the “Cambrian explosion,” fossilized records from this time provide glimpses into evolutionary biology when the world’s ecosystems rapidly changed and diversified. Most fossils show the organisms’ skeletal structure, which may or may not give researchers accurate pictures of these prehistoric organisms. Now, researchers at the...

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...
