Enniskillenus is an odd and rare fish to find which was originally assigned to the family Palaeorhynchidae, but more recently to Xiphiinae. This skull is clearly recognisable for the ornate patterns on the gently curving frontal bones on the top of the skull. Recently, local collector Dan Hogburn found a more complete, larger specimen which showcases more of the elongated rostrum, abrasive teeth and ‘keel-like’ deep lower jaw with fused symphysis. The rostrum of this new specimen looks very much like Aglyptorhynchus and with the characteristic ventrally expanded flange on the posterior of the maxilla bone, I’m wondering whether Enniskillenus isn’t in fact representative of the skull of an Aglyptorhynchus (more research however needed).
