Densignathus rowei is the second tetrapod to be found at Red Hill, Pennsylvania; the first Red Hill tetrapod is Hynerpeton bassetti, while an isolated and unattributed humerus (ANSP 21350) has also been found. The Densignathus fossil consist of a single lower jaw. The jaw is robust and has a mosaic of features, some of which suggest a more derived status (e.g., a partially enclosed mandibular canal), while others suggest a more primitive fish-like status (e.g., the presence of coronoid fangs).
A detailed presentation of associated fauna and flora is presented in Who's Who at Red Hill.
