Abstract:
| This is the first monographic study of the Silurian Crinoidea of the British Isles since 1839. In Part I, we describe the Disparida including three families - the myelodactylids (one genus, six species), pisocrinids (two genera, five species) and calceocrinids (three genera, twelve species). Myelodactylids and calceocrinids are most diverse in the Wenlock, but are not known from the Ludlow. Three species of pisocrinids are known from the Ludlow. Two new species are described, the calceocrinids Calceocrinus nidamentum sp. nov. and Chirocrinus broweri sp. nov., both from the Much Wenlock Limestone Formation of the Dudley area. |
