description
DESCRIPTION FSAC Bouj- 350 (Fig. 5 M) is the lateral pubic process of a right pelvis. Its distal extremity is robust and shows an irregularly lentoid epiphysis.
discussion
REMARKS The morphology of this elongate process corresponds to that of the pubic process of the extant Dermochelys Blainvillle, 1816, in which this struture is longer than the median main body of pubis, while the pubic process is shorter and wider at its base in cheloniids. Compared with Dermochelys, in Bouj- 350 the process is slightly shorter than its basal width, the epiphysis is anterolaterally shorter and the lateroexternal border is slightly curved. The presence of a dermochelyid associated with a cheloniid in Gueran is not strange, since the same association occurs in the Priabonian of Ad-Dakhla (Morocco) and Fayum (Qasr-el-Sagha) (Egypt) (Andrews 1906; Zouhri et al. 2017). Scarce remains of these two taxa in the three localities, and absence of preserved pubic processes in Ad-Dakhla and Fayum do not provide further information.
