Abstract
Both Hesperornis and Ichthyornis are toothed birds; they and Archaeopteryx share broad flattened teeth with highly expanded roots. The teeth of Ichthyornis have been reported to have been set in sockets as were those of Archaeopteryx , but new specimens of Ichthyornis show the teeth set in a groove as in Hesperornis . These new fossils are from an adult but not old bird; thus, the presence or absence of tooth sockets in birds may be dependent on age.This publication has 10 references indexed in Scilit:
