Description: The elongated head with a slender outline, long jaws set with small teeth betray this unusual fish as a predator. Some scientists think they may have used these elongated jaws in a side-slashing movement to capture their prey. The slender shape and broad caudal fin would seem to indicate that they could be highly efficient pursuit predators. This is a recently-described taxon, having been published in 1986, and one that is rarely offered for sale. They have no recent relatives, and died out in the Late Cretaceous. This is a most unusual juvenile example, and is the smallest I have seen. It comes from a quarry in en-Nammoura from strata some 2 million years younger than those at Haqel and Hajoulas.
