This paleontological restoration is inaccurate, or its accuracy is disputed.
Reason: Animal is restorated with the aptychi forming some kind of hood or cap on top of the head. However, the aptychi are long considered as modified lower jaws and, even though they may have had a function as an operculum, they are not homologous to the nautiluses hood and did not sit on top of the head, and tentacles are all conjoined.
