DWARVES AND GIANTS
THE LYTOCERATIDS

While almost all ammonites from the Jurassic and Cretaceous periods are closely related to each other, the Lytoceratids form a separate group that split off a good 200 million years ago. Their shape and suture lines are very characteristic and have hardly changed over the course of millions of years. Their size, on the other hand, varies enormously!

Lytoceras inhabited the open sea, could swim relatively well and quickly and fed predatorily on other marine animals.
