Treatment

Hemipristis curvatus (Dames, 1883)

EXAMINED MATERIAL. — Five broken isolated teeth, figured material includes FSAC Bouj-343.

DESCRIPTION

An upper tooth ( Fig. 4D View FIG ) belonging to the snuggle tooth shark Hemipristis curvatus was recovered from the Locality 1. The crown is compressed labio-lingually, slanted distally with unserrated mesial cutting edge.

REMARKS

The snuggle tooth shark, Hemipristis curvatus is known in all the tropical seas during the late Eocene, from Western Neotethys (e.g., Case & Cappetta 1990; Mustafa & Zalmout 2002; Underwood et al. 2011) to western central Atlantic (e.g., Case & Borodin 2000). Its occurrence in the middle Eocene is less usual ( Underwood et al. 2011). Only two teeth were recorded in MI ( Underwood et al. 2011), it becomes common from the GE A-C (around the

Bartonian/Priabonian boundary) and within the rest of the BQ (Priabonian).
