Kurzfassung
Ein Vertreter der Tommotiidae,Camenella parilobata n. sp., wird auf Grund einer Sammlung von mitralen und seilateri Skleriten aus der unterkambrischen Khairkhan-»Formation« der westlichen Mongolei beschrieben. Die genaue Dokumentation des Zusammenauftretens von Sklerit-Typen ist für die taxonomische Analyse der problematischen Tommotiidae und verwandte Gruppen unerläßlich; die meisten »Tommotiiden« (sensu lato) sind bisher nur aus einigen isolierten Skleriten bekannt, die ein unbekanntes Variabilitäts-Spektrum vertreten. Bevor eine genaue Analyse der Zusammensetzung des Skleritoms und der Mikrostruktur der Skleriten von Vertretern aller Gattungen durchgeführt ist, kann die supragenerische Klassifikation nur spekulativ sein.
Abstract
The tommotiidCamenella parilobata n. sp. is described on the basis of a collection of mitral and sellate sclerites from the Lower Cambrian Khairkhan »Formation« of western Mongolia. The detailed documentation of co-occurrence of sclerite types is essential for the taxonomic analysis of the problematic Tommotiidae and related groups; most »tommotiid« (sensu lato) taxa are still known only from a few isolated sclerites representing an unknown spectrum of variability. Until a detailed analysis of the scleritome composition and sclerite microstructure in representatives of all genera has been made, any suprageneric classification can only be speculative.
