Gen. et sp. indet. EXAMINED MATERIAL. — FSAC-Bouj-372 (Fig. 5G), proximal fragment of a right pectoral spine. DESCRIPTION Only the left part of the proximal portion of the spine is preserved. The cleithral process is short with a thick and smooth external surface. The ornamentation of the base of the shaft is formed by ridges and thin tubercles. REMARKS The spine is too fragmentary to be attributed to a siluriform family, but the ornamentation pattern of the spine body is reminiscent of ariid pectoral spines., Published as part of Zouhri, Samir, Gingerich, Philip D., Khalloufi, Bouziane, Bourdon, Estelle, Adnet, Sylvain, Jouve, Stéphane, Elboudali, Najia, Amane, Ayoub, Rage, Jean-Claude & Tabuce, Rodolphe, 2021, Middle Eocene vertebrate fauna from the Aridal Formation, Sabkha of Gueran, southwestern Morocco, pp. 121-150 in Geodiversitas 43 (5) on page 132, DOI: 10.5252/geodiversitas2021v43a5, http://zenodo.org/record/4605963

Gen. et sp. indet. EXAMINED MATERIAL. — FSAC Bouj-371, (Fig. 5E), incomplete fin spine. DESCRIPTION This proximal fragment of fin spine includes articular processes and a proximal portion of the shaft. The shaft is smooth and shows a lentoid cross-section.The anterior surface is dissymmetrical, the right half showing a depression. The posterior surface is crossed by a thin posterior sulcus. The lumen is well-marked but the basal bar, which extends from the two lateral articular processes, is broken. The anterior and posterior articular processes are not very developed, but they were probably smoothed by erosion. REMARKS Based on the absence of ornamentation and the morphology of the articular processes, the spine Bouj-371 is comparable to unpaired fin spines of extant percomorphs, like serranids or latids.

Clade EUSUCHIA Huxley, 1875 sensu Brochu (2003) Eusuchia indet. EXAMINED MATERIAL. — FSAC Bouj-410, could be the (?) ninth cervical vertebra; FSAC Bouj-1b, anterior? cervical vertebra; 400, posterior dorsal vertebra; 1a, first caudal vertebra; 124, caudal vertebra; 96, two fragments of large dorsal osteoderms; 94, fragment of osteoderm. DESCRIPTION Numerous postcranial remains have been found in Gueran.These include five procoelous vertebrae and several fragments of osteoderms. FSAC Bouj-410 is a posterior cervical vertebra (Fig.7A). It bears a long hypapophysis, and the location of the diapophysis and parapophysis suggests that it could be the ninth cervical vertebra. Bouj-1b is a more anterior cervical (Fig. 7B), but it is not possible to determine its exact location in the vertebral column. FSAC Bouj-400 is an isolated procoelous centrum lacking most of the neural arch (Fig. 7C). The transverse process is high on the centrum, which indicates that it is a dorsal vertebra. A first caudal vertebra with a biconvex centrum is preserved (Fig. 7D). The osteoderm fragments have their dorsal surfaces densely ornamented with deep pits (Fig.7 F-H). Bouj-96 is a fragment of large and thick osteoderm with a smooth anterior articular surface., Published as part of Zouhri, Samir, Gingerich, Philip D., Khalloufi, Bouziane, Bourdon, Estelle, Adnet, Sylvain, Jouve, Stéphane, Elboudali, Najia, Amane, Ayoub, Rage, Jean-Claude & Tabuce, Rodolphe, 2021, Middle Eocene vertebrate fauna from the Aridal Formation, Sabkha of Gueran, southwestern Morocco, pp. 121-150 in Geodiversitas 43 (5) on page 138, DOI: 10.5252/geodiversitas2021v43a5, http://zenodo.org/record/4605963, {"references":["BROCHU C.
