This paleontological restoration is inaccurate, or its accuracy is disputed.
Reason: Both undescribed material and similarities with other chondrichthyans indicates an appearance and alignment with the cochliodontiformes for the listracanthidae. Ctenacanth-like reconstructions such as this one are extremely implausible. Petrodus-like ventral denticles absent.
