Description: Known for its incredibly well-preserved fish and crustaceans, the sublithographic limestone of the Cretaceous of Lebanon also preserved incredible detail here as well in this newly-described taxon known as Triplomystus oliggoscutatus. The genus was erected in late 2003, one of 6 new genera established at that time. The en-Nammoura location is quite different in its fauna from either Hajoula or Hakel. It is thought to have been slightly younger than either of those locations. Based upon a high level of preserved terrestrial plants, it is further thought to have been closer to land, albeit islands rather than the continental coastline. Fish are far more rare at en-Nammoura, with very few recorded multiple specimens found. The taxon bears some resemblance to the roughly contemporary Diplomystus (which endures until the Eocene). It differs by having 3 series of scutes present on the dorsal surface and postpelvic region. This is the FIRST example of this taxon I have been able to acquire, and would make a welcome addition to any comprehensive collection of fossil fish.
