The specimen is preserved in a lenticular calcareous nodule. It retains two whorls of planispiral phragmocone and a succeeding retroversal shell. Unlike most ammonites were have a short tentacles, Pravitoceras has a long tentacles that is used for catching preys.

Ammonites use their ink to help their prey get away. When they feel threatened, they can shoot large amounts of ink into the water using their siphon. Scientists believe that by pumping air through the inside chambers of the shell, the air-pump-like siphuncle helped create buoyancy and transport ammonites through the water. Ammonites and nautiluses, on the other hand, have thick exterior shells that protect them from predators. The Nostoceras can shoot itself into the black ink clouds, ramming towards the predators.

Nautiluses and ammonites are shy toward humans and unique among other cephalopods, though, because they have hard outer shells that help protect them from predators. This is the only known ammonite that was very curious about enemies, including humans, because of their higher IQ.

In the past, Pravitoceras once lived during Late Cretaceous from 84.9 to 70.6 million years ago in Japan.
