Microschedia

Microschedia is an enigmatic fossil bilaterian known from four specimens from Lower Cambrian Amouslek Formation deposits in Morocco.

Fine hair-like projections extend beyond the edge of this almost-flat, firm (but non-mineralized) "shell", which bears no trace of muscle scars.

[1] Although there are problems with both brachiopod and cnidarian interpretations, no other animal group provides a good match for these fossils.

[1] An affinity with the stem-group brachiopod Mickwitzia is currently considered to be the most likely interpretation for this fossil.

[2] The enigmatic Cambrian and Ordovician animals Heliomedusa, Marocella and Conchopeltis warrant comparison, although again large differences exist between these taxa.
