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...

Story Of Ancient Invasive Species North America
2013-08-22 11:59:50

Brett Smith for redOrbit.com - Your Universe Online A new study from researchers at Ohio State University tells the story of an invasion and domination that took place around 450 million years ago in North America. During the Ordovician period, a dramatic ecological shift occurred near what are now the Appalachian Mountains, as represented in the fossil record. In the study, which was published recently in the journal PLOS ONE, Ohio State paleontologists provide evidence of significant...

Oldest Super Predator Had Highly-acute Vision
2011-12-08 06:25:03

Paleontologists working on fossils from Kangaroo Island in South Australia have discovered that the Earth's first apex predator had highly acute vision that rivaled or exceeded that of most living insects and crustaceans. The researchers from South Australian Museum and University of Adelaide discovered exceptionally preserved fossil eyes of the top predator in the Cambrian ocean from over 500 million years ago: the fearsome Anomalocaris. The species is considered to be at the top of...

By Greg Hand, University of Cincinnati Fossilized "snapshots" provide University of Cincinnati paleontologist Carlton E. Brett and colleagues with new insights into the behavior of ancient marine creatures. Brett will present this research March 20 at the regional meeting of the Geological Society of America in Pittsburgh. Few specimens inspire greater thrills among fossil collectors than a complete trilobite. These ancient arthropods "“ relatives of lobsters, spiders and insects...

Researchers use a ground-breaking technique that reveals a relationship between cooler temperatures and Earth's second largest mass extinction, which occurred about 450 million years ago In the Late Ordovician Period of Earth's geologic history, about 450 million years ago, more than 75 percent of marine species perished and Earth scientists have been seeking to discover what caused the extinction. It was the second largest in Earth's history. Now, using a new research method, investigators...

Collapse of Earth's marine life 378 to 375 million years ago holds key An influx of invasive species can stop the dominant natural process of new species formation and trigger mass extinction events, according to research results published Dec. 29 in the journal PLoS ONE. The study of the collapse of Earth's marine life 378 to 375 million years ago suggests that the planet's current ecosystems, which are struggling with biodiversity loss, could meet a similar fate. Although Earth has...

The meters-long, carnivorous "shrimp" from hell that once ruled the seas of Earth a half billion years ago may have been a real softy, it turns out. A new 3-D modeling of the mouth parts of the Anomalocaris, along with evidence that these parts were not hard like teeth, but flexible, shows that the famed predator could not have been munching on the hard shells of trilobites and other such creatures of the early seas. What's more, there is no evidence from fossilized stomach contents or feces...

British scientists have determined an ice age occurring about 440 million years ago that's been regarded as a brief period actually lasted 30 million years. University of Leicester geologists said their findings suggest that during the ancient ice age, global warming was curbed through the burial of organic carbon that eventually led to the formation of oil -- including the hot shales of North Africa and Arabia that constitute the world's most productive oil source rock. The ice age has been...
