Salut Crozo,

nice piece;-) A fine Dicranurus you have there.

Only a short remark, please try to avoid the term "Hamar Lagdad Formation", such a formation did not exist. In fact the horizons with Dicranurus are a part of the Ihandar Formation, named after a small village at the north-eastern side of the Issoumour. The location is part of the Maider basin and has nothing in common with the Hamar Lagdad mud mound facies.

regards and keep up your great work.

PS: I have to add this one into the Odontopleurida;-)
