When: Upper Member (Headon Beds Formation), Late/Upper Eocene (37.2 - 33.9 Ma)

• This author numbers beds for the whole area (multiple formations) in one series, these are beds 28-29 numbered bottom to top. Prestwich says that this bed belongs to the "Upper Group" of the fluvio-marine series, I have correlated it with Bosma's naming system as the Upper Headon Beds.
