Camenellan

The camenellans, consisting of the genera Camenalla, Dailyatia, Kennardia, Kelanella, Wufengella and Lapworthella, are a (probably monophyletic) group of Tommotiid invertebrates from the Cambrian period, reconstructed as sister to all others[clarification needed] (plus brachiopods and phoronids).

They are primarily known from isolated sclerites, but are believed to have a scleritomous, Halkieria-like construction.

[2][3] This was confirmed by the discovery of Wufengella, known from articulated remains, which showed camenellans to be mobile, worm-like animals.

[4] Dailyatia and Camenella have distinct dorsal (symmetrical) and lateral (asymmetric) sclerite morphologies.

[5] Dailyatia has a similar double-mounded structure at the tip of its A type sclerites.
