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

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.

Of all the famous fossil localities in the world — Mongolia’s Flaming Cliffs, Tanzania’s Olduvai Gorge, Wyoming’s Green River, Germany’s Solnhöfn Quarry — perhaps none is as widely celebrated as British Columbia’s Burgess Shale.

A study by University of Michigan paleontologist Tomasz Baumiller and colleagues finds that sea urchins have been preying on marine animals known as crinoids for more than 200 million years and suggests that such interactions drove one type of crinoid---the sea lily---to develop the ability to escape by creeping along the ocean floor.

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...
