In this species the dorsal centra are wide, low, and short, and of a
regular oval outline. The articular cones are shallow, and have their
bottoms but slightly above the centre. The neurapophysial facets are
deep, with prominent borders, and the diapophyses are sessile. The
chief peculiarity is that the under surface of the centrum has no
markings of any kind.
