Soft body fossils of extinct ’lamp shell’ digitally reconstructed

18.08.2005


A team of American and British scientists have identified and digitally reconstructed the first example of a fossilized brachiopod complete with its pedicle, the stalk attaching it to the sea floor, and its lophophore or feeding organ, according to a report in the journal Nature.


Lamp Shade’ fossil recovered from 250 million year old Herefordshire, U.K. lava ash



Brachiopods, the so called "lamp shells," are rare today, but are some of the best known fossils from the Paleozoic era -- 542 to 251 million years ago. Our knowledge of these extinct forms was previously based almost entirely on their shells, which are all that normally fossilize.

Derek Briggs, professor of geology and geophysics, and director of the Yale Institute of Biospheric Studies, with his colleagues Mark Sutton at the Imperial College, University of London, Derek Siveter at University of Oxford and Professor David Siveter at University of Leicester conducted their research on the fossil deposits in Herefordshire, U.K.


This extraordinary trove of fossil records was buried under the sea in volcanic ash that is 425 million years old. The site is unusual because it yields fossils of the entire animals, including soft body parts that the researchers then can reconstruct digitally.

"This specimen is particularly interesting as several smaller brachiopods have attached themselves to its shell, two of them also preserving pedicles," said Briggs.

The brachiopod belongs to an extinct group, and this work reveals that its pedicle differs from that on living forms. Previous assumptions that extinct brachiopods were very similar to modern examples may thus be too simplistic.

Other specimens of interest from the volcanic ash at Herefordshire that were recently reconstructed by the team include an ancient sea spider and the oldest fossil animal that is "definitively male." [see Release #1 and #2 below]

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
