What is "anguillavus"

Anguillavus is an extinct genus of prehistoric bony fish that lived during the upper Cenomanian of Lebanon and the United States. It was originally described as a primitive eel that still had pelvic fins, unlike modern eels. In 1981, the holotype of A. hackberryensis, from Cenomanian-aged marine strata in Kansas, was reexamined, whereupon the genus was then redescribed as a genus of dercertid aulopiform fish.
