The following diagrams and sketches display some important brachiopod morphology. spirifer: [noun] a large genus (the type of the family Spiriferidae) of articulate brachiopods that have the arms supported within the shell by long spirally coiled spiralia which form a pair of cones with their apexes directed more or less laterally toward the ends of the long hinge line and that abound in Silurian, Devonian, and ...Brachiopods are the most abundant fossils in Wisconsin. Most people are not familiar with living brachiopods because modern species inhabit extremely deep regions of the world’s oceans, and their shells are rarely found on modern seashores. But during the Paleozoic, thousands of different species of brachiopods teemed in the near-shore and deep-sea environments of Wisconsin.…
