What are Pygmarrhopalites?

Answer 1

Pygmarrhopalites are a genus of extinct cephalopods that belong to the subclass Ammonoidea, commonly known as ammonites. These marine mollusks lived during the Late Cretaceous period and are characterized by their distinct coiled and chambered shells, which often exhibit intricate patterns. Fossils of Pygmarrhopalites provide valuable insights into the biodiversity and evolutionary history of marine life during that era. Their presence in the fossil record helps paleontologists understand ancient marine environments and the conditions that led to their extinction.
