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...
