Instructive taphonomic principles are demonstrated by the skeletons of dead invertebrates. Bivalves have resistant skeletons and are common fossils. The thin-valved razor shells, Ensis spp., have a good fossil record despite being fragile. This may b

The Mississippian (Lower Carboniferous) succession of Derbyshire contains numerous crinoid specimens, but they remain poorly documented. Although these well-lithified limestones may include abundant crinoids, they are difficult to study; better resul

Summary Fossil echinoderms derived from the Chalk occur rarely as clasts eroded from erratic rafts on the beaches of north Norfolk and are almost invariably represented by the holasteroid echinoid Echinocorys scutata (Leske). A small collection of ot

Restorations of the morphology, ecology and function of fossil invertebrates may be inferior to those of groups more familiar to the public and artist, such as tetrapods. This is illustrated by an extreme example, a drawing of the Lower Jurassic pseu
