Tytthostonyx is a genus of prehistoric seabird. Found in the much-debated Hornerstown Formation which straddles the Cretaceous-Paleogene boundary 65 million years ago, this animal was apparently closely related to the ancestor of some modern birds, such as Procellariiformes and/or "Pelecaniformes". A single species is placed herein, Tytthostonyx glauconiticus.[1]
It has been placed into a family of its own, Tytthostonygidae.[1]
