Gregoriidae is an extinct family of early chondrichthyans from the Carboniferous period.[1] It currently includes three described genera: Gregorius, Srianta, and Bealbonn. This family includes remains formerly ascribed to "Desmiodus," which is now considered a nomen vanum.[2] The relationships between the included genera are not entirely clear.[3] Fossils are known from Serpukhovian-aged formations including the Bear Gulch Limestone and Surprise Canyon Formation.[4]
