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...

Scientists Study Emergence Of Ray-Finned Fish
2013-07-22 17:47:50

Brett Smith for redOrbit.com – Your Universe Online Just like the rapper Drake, ray-finned fish started from the bottom – now they’re here. The vertebrate class of fish, which comprises 99 percent of all fish species, arose from a small, shell-crushing predatory fish called Fouldenia that survived a massive extinction event 359 million years ago, according to a new report in Zoological Journal of the Linnean Society. "This event 359 million years ago is called...

Ancient Fossils Of Tough Fish Shed Light On Evolution Of Four-Footed Animals
2013-03-28 08:08:22

April Flowers for redOrbit.com - Your Universe Online Describing life in the Devonian period in what is now northern Canada, Dr. Ted Daeschler of Drexel University said, "We call it a 'fish-eat-fish world,' an ecosystem where you really needed to escape predation.” The famous fossil fish species Tiktaalik roseae lived in this environment 375 million years ago. Daeschler, associate professor at Drexel University in the Department of Biodiversity, Earth and Environmental Science,...

First Fruitful, Then Futile: Ammonites Or The Boon And Bane Of Many Offspring
2012-04-23 08:48:13

For 300 million years, they were the ultimate survivors. They successfully negotiated three mass extinctions, only to die out eventually at the end of the Cretaceous along with the dinosaurs: Ammonoids, or ammonites as they are also known, were marine cephalopods believed to be related to today's squid and nautiloids. Ammonoids changed their reproductive strategy early on in the course of evolution. However, what was once a successful initial strategy may well have proved to be a fatal...

Ancient Forest In NY More Diverse Than Scientists Thought
2012-03-02 05:38:06

[ Watch the Video ] After unearthing a previously unknown portion of one of the planet´s earliest known forests, archeologists say the fossils of 385-million-year-old trees reveal a far more diverse ecosystem than researchers had previously thought existed. Partially uncovered by quarry workers in 1870, the ancient forest beneath the tiny town of Gilboa, N.Y. has been of intense interest to paleobotanists since the 1920s. Dating back to the Devonian Period, researchers early on...

University of Oregon scientist finds evidence that the transition occurred in humid, wooded floodplains A small fish crawling on stumpy limbs from a shrinking desert pond is an icon of can-do spirit, emblematic of a leading theory for the evolutionary transition between fish and amphibians. This theorized image of such a drastic adaptation to changing environmental conditions, however, may, itself, be evolving into a new picture. University of Oregon scientist Gregory J. Retallack,...

Mucrospirifer
2014-01-12 00:00:00

Mucrospirifer is a genus of extinct brachiopod of the order Spiriferida. This genus is sometimes known as the “butterfly shells.” Fossils of this genus occur mostly in the Middle Devonian strata. When alive, this genus mainly lived in muddy marine sediments, and were attached to the sea floor via its pedicle (foot). The bi-convex shell was about an inch long, and sometimes grew to 1.6 inches. The shell has a fold, groove and rod-like structure. It is elongated along the hinge line,...

Atrypa

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...

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
