Hybodus (from Greek: ύβος hybos, 'crooked' and Greek: ὀδούς odoús 'tooth')^[2] is an extinct genus of hybodont that lived from the Middle Triassic to the Late Cretaceous periods.^[3] Species closely related to the type species Hybodus reticulatus lived during the Early Jurassic epoch.^[1] Numerous species have been assigned to Hybodus spanning a large period of time, and it is currently considered a wastebasket taxon that is 'broadly polyphyletic' and requires reexamination.^[4]^[5]^[1]
