Brachiopods are (perhaps all too) familiar to any geology student who has taken an invertebrate paleontology course; they may well be less familiar to biology students. Even ...Brachiopod shells are an obvious predator deterrent; however, most species have relatively thin shells and the fossil record suggests that predators may be able to bore through them, if rarely. It appears that the flesh of brachiopods is unpalatable and they therefore are not generally subject to predation, particularly in the presence of ...The brachiopods were particularly abundant in the Palaeozoic but have progressively decreased in diversity toward the Recent. From the about 5,000 described genera, and about 30,000 described species, the numbers of extant taxa, some being know as fossils, are frequently updated.Since some 95% of all brachiopod taxa are extinct, the fossil record is the primary source of data to frame and test models for the evolution of the phylum.

This is a brachiopod fossil of the species Paraspirifer bownockeri that has been partially replaced by iron pyrite. It comes from the Devonian-aged Silica Shale near Sylvania, Ohio. The quarries where these brachiopods used to be found are now closed to collectors so they are much harder to acquire.Sign in here. Rhynchonellids are hard to identify by exterior morphology as they often need to have their internal structures visible to be sure of an id.
