 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.The vertebrae are amphicoelous (hourglass-shaped) from the side, but not strongly so, and are covered in small pits.
