The Silurian was a period of increasing gastropod diversity in most gastropod clades, as part of the recovery from the end-Ordovician mass extinction. Species with high spires became more common, as did taxa with slits at their apertures (Fryda et al 2008: p. 261). Platyceratids also diversified at this time.
