Two new Jurassic Bryozoa from southern England
£1.00
Reptomultisparsa tumida sp. nov. and Reptoclausa porcata sp. nov. are described respectively from the Bathonian Bradford Clay of Bradford-on-Avon and the Aalenian/Bajocian Inferior Oolite of the Cotswold Hills. The genus Reptoclausa was previously known only from the Cretaceous. Reptoclausa colonies have autozooecia located on longitudinal ridges which are separated by furrows composed of kenozooecia. This unusual arrangement of zooecia can be explained by the action of physiological growth gradients during colony life.
