By Friedman, Matt; Blom, Henning ABSTRACT- A new actinopterygian, Cuneognathus gardineri new genus and species, is described from the Devonian (Famennian) Obrutschew Bjerg Formation of East Greenland on the basis of multiple incomplete specimens. Cuneognathus most closely resembles Limnomis from the Famennian Catskill Formation of Pennsylvania, and, like that taxon, is known exclusively from freshwater deposits. A cladistic analysis with an ingroup of 13 actinopterygians and an outgroup...

THOMPSON FALLS, Mont. -- Paul Chambers' quarry at the base of the Cabinet Mountains is a hard-rock bazaar. Choose your look: Smooth slabs? Stackable stones? How about some football-size rock ornaments? In the hands of designers, the rock will become garden tables, waterfall spillways, rustic fireplaces or exterior facades. Chambers and his customers see those and more in the stone his crew extracts and moves to the outdoor showroom. He is in a growth industry. State records in Montana show...

(Kingston, ON) "“ Geologists at Queen's University have discovered that the time it takes for mountain ranges to form is millions of years shorter than previously thought. This controversial finding could have implications for our understanding of other geological processes that shaped the Earth, says Professor James Lee and postdoctoral fellow Alfredo Camacho of Queen's Geological Sciences and Geological Engineering Department. The study will appear in the June 30 edition of the...

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 (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...
