 However, the latter is also unlikely because Harderian glands are usually placed inside the eye socket.Franz Nopcsa suggested that the maxillary fossae housed venom glands (which may have been derived from lacrimal glands), with the ridged canines and the notches behind the canines allowing the venom to flow passively into the victim's bloodstream.This hypothesis was widely accepted throughout the 20th century and the characteristic morphology of "Euchambersia" was used to support possible venom-bearing adaptations among various other prehistoric animals, including the therocephalian "Ichibengops".
