54mm heteromorph ammonite on 166mm matrix

Ancycloceras sp. is a fascinating heteromorph ammonite from the Early Cretaceous, easily recognized by its uncoiled, hook-shaped shell. Unlike typical spiral ammonites, Ancycloceras featured a straight section that curved into a hook, giving it a unique and eye-catching appearance. This strange shell shape likely influenced how it floated or swam in the ancient seas. With its intricate ribs and rare form, Ancycloceras sp. is a bold example of nature’s creativity during the age of dinosaurs.
