 The flared rims of the front and rear surfaces of the pleurocentum possesses small structures which would have formed tongue-and-groove articulations with other vertebrae.The "tongue" projected forward from the front rim while the "groove" was present between two projections on the rear rim.The only definitive feature classifying this genus as a nectridean lies in the fact that there are also two pairs of joint plates (zygapophyses) on each end of the vertebrae.
