Camenellan

The camenellans, consisting of the genera Camenalla, Dailyatia, Kennardia, Kelanella and Lapworthella, are a (probably monophyletic) group of Tommotiid invertebrates from the Cambrian period, reconstructed as sister to all others (plus brachiopods and phoronids). They are known from isolated sclerites, but are believed to have a scleritomous, Halkieria-like construction. Dailyatia and Camenella have distinct dorsal (symmetrical) and lateral (asymmetric) sclerite morphologies.The same has been asserted for Lapworthella even though that has not always been the common perception.
