Century Dictionary and Cyclopedia
    • odontornithes Birds with teeth; a group of Aves having true teeth implanted in separate sockets or in a continuous groove. All the recognized Odontornithes are of Mesozoic age, but such birds doubtless continued into the Oænozoic period. The Archæopteryx was Jurassic; the other leading genera, Ichthyornis and Hesperornis, were Cretaceous. The latter two form types of two subclasses of birds, Odontotormæ and Odontolcæ, the first-named typifying a third subclass called Saururæ. See cuts under Archæopteryx and Ichthyornis.
