This shark lived during the late Oligocene epoch and Neogene period, about 28 to 1.5 million years ago, and ranged to a maximum length of 60 ft.

[ 13 ] [ 14 ] The subadult specimen with the largest vertebra showed that it could reach lengths of 4.3–7.07 m (14.1–23.2 ft), so a 10 m (33 ft) length is possible, but more analysis is required for verification.
