Spectacular piece of ± 15.1 × 10.4 cm; with a complete crinoid of ± 22.4 cm (the straight part measures 11.2 cm).

* Trombonicrinus (col.) Hanshessi gen. et sp. nov., is a species of crinoids of unusual morphology and is based solely on the stem. It comes from the Devonian of Tafraoute, Anti Atlas Mountains, Morocco. It is a long crinoid stalk with a circular section, which narrows distally throughout its length, the union is distal by short, pointed and non-segmented pseudoradic. The stem of the crinoid was growing towards the substrate. The specimen is considered complete except for the crown. The loss of the crown is most likely due to an autotomy. (Stephen K. Donovan, Johnny A. Waters & Mark S. Pankowski
