Novocrania anomala (Müller, 1776)

Dorsal valve exterior smooth to hummocky with concentric growth lamellae, dorsal valve interior with adductor muscle scars flush with valve surface or slightly raised, small anterior muscles commonly attached to a tiny anterior septum, ventral valve sometimes organic, commonly partly calcitic/partly organic or completely calcitic, ventral valve punctate (when calcitic), rostellum organic, ventral posterior adductor muscle scars organic, in dead shells ventral muscle scars and rostellum latent.

This dataset contains the digitized treatments in Plazi based on the original journal article Jeffrey H Robinson (2017): A review of all Recent species in the genus Novocrania (Craniata, Brachiopoda). Zootaxa 4329 (6): 501-559, DOI: 10.11646/zootaxa.4329.6.1

Abstract

The Recent species in the craniid genus Novocrania are reviewed, based on the examination of actual specimens wherever possible, especially for species named from one or a few specimens. The fourteen Recent species currently in the literature are reduced to eight; five species names are synonymized. One species name was given to a specimen that is not a craniid. The wide morphological ranges of the remaining Novocrania species are described and figured and the extended geographical ranges illustrated. Diagnoses of the remaining species are provided. The long-standing debate whether Novocrania anomala and N. turbinata are separate species or synonyms is resolved; they are separate species. New molecular analyses and a relative time-tree are provided by Cohen et al. (Appendix 1), the time-tree is calibrated herein and the results of Cohen et al. (2014; Appendix 1) and the time tree are discussed. The likelihood of craniid long-distance migration based on their geographical ranges is discussed.
