40 teeth (all types) from the type locality, 2 teeth from LACM locality 4318 (LACM 117298, incomplete tooth lacking one cusp and one root lobe; LACM 117299, incomplete tooth lacking tips of both root lobes and the tips of all three cusps) [2517];

Description
Original diagnose of WELTON, 1979 [2517]: Chlamydoselachus with teeth almost twice the size of known adult C. anguineus; roots meso-distally broad and labio-lingually short; antero-lateral root length-width ratio almost 1:1; mesial and distal root edges broadly expanded below crown and abruptly concave medially at level of central labial foramen; root lobes moderate to weakly bilobate; lingual transverse groove broad and short; crown as in anguineus but with robust cusp bases and strongly developed labial transverse ridges on most antero-lateral teeth.
