Solute

Soluta is an order of echinoderms that belongs to the extinct class Homoiostelea who lived from the Middle Camrian to the Early Devonian. They have a strongly asymmetrical flattened theca composed of plates similar to each other. Its exclusive characteristic is the presence of two appendages arranged one at each end of the theca. One is the classroomcophore. The other is exclusive to homoiosteles; It is short and located in the anterior part, and has a groove on its underside interpreted as a food structure.

The Fezouata deposits, near the Moroccan city of Zagora, are providing a rich sample of a fauna similar, although later in time, to the famous Burgess Shale (Canada). We are talking about fossils between 480 and 472 million years old. The age indicates that the Burgess Shale type communities were not restricted, as was believed, to the early stages of the Cambrian and then suddenly disappeared, but rather they survived much longer, coexisted with the later fauna and would be the normal type of deep sea fauna throughout the planet. So Morocco was an ocean and was over the South Pole.
