We sectioned a shaft fragment of a femur of S. geographicus (AMU-CURS-233) recovered from a site next to the gas pipeline at El Mamón locality, Urumaco, Falcón state, Venezuela (11°13′1.46″N; 70°16′51.2″W). The shaft section was roughly oval shaped, with the longest axis of 8 cm and a perpendicular shorter axis of 6.2 cm. The bone was cut with an iron hand saw and processed afterward, following standard petrographic thin-sectioning procedures (65). The thin section was studied and analyzed using a compound microscope (DM 2500M, Leica) with a digital camera (DFC 420C, Leica). Comparative material of S. geographicus included already published shell bone sections (59), and overall bone compactness was calculated using Bone Profiler software (66).
