Here's what elasmo.com recounts of the taxonomic status of this species:

QUOTE

Kozlov (2001) described Trigonotodus alteri for enlarged cuspleted Alopias-like teeth from the Ashley Marl (Early Oligocene) of SC, based on the similarities with the much smaller T. tusbairicus KOZLOV 1999 (Middle Eocene, Kazakhstan). When erecting this genus, Kozlov (1999:157) included it as an otodontid; however, by 2001 it was included as an alopiid and he moved Alopias grandis to this genus. Lacking dentition-design details for either taxa this website will continue to attribute grandis-like teeth to "Alopias" and tentatively accept Trigonotodus for the Early Oligocene cuspleted design.
