Description
Summary:Physogaleus sp. MATERIAL. — 40 isolated teeth, figured material includes FSAC Bouj-340, 341, 342 and 343. DESCRIPTION AND REMARKS Among the smaller carcharhinids, teeth of Physogaleus sp. (Fig. 4 A-C) are relatively frequent in both localities. Two coeval species of Physogaleus are redundant in the middle Eocene deposits. It concerns the larger P. secundus (Winkler, 1876) widespread in most middle Eocene deposits of North Atlantic (see Cappetta & Case 2016) and Neotethys, and the smaller P. tertius (Winkler, 1876) recorded in the same areas (Cappetta 2012). With very tenuous differences, both species may enter in the morphological variability of the other. Our material is well conserved, and teeth appear larger (up to 1.5 cm) than those of northern representatives. : 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 127, DOI: 10.5252/geodiversitas2021v43a5, http://zenodo.org/record/4605963 : {"references": ["CAPPETTA H. & CASE G.
