 Vertebrae which are believed to have been part of the sacral (hip) region have shorter neural spines than those of the back, and are sightly titled backwards.Less extreme neural spine bifurcation is also known in the early diplocaulid "Diceratosaurus" and some specimens of the urocordylid "Ctenerpeton", two other nectrideans.In addition, the pitted vertebrae are somewhat similar to those of diplocaulids.
