The median caudals differ by having a less depressed, lessexpanded, and more elongate centrum, and the diapophyses directeddownwards and outwards. The neural canal is much smaller, thechevron bone articulated nearly entirely with the hind part of thecentrum, there being scarcely any impression for its articulation onthe anterior
