Deviatoida

Deviatoida is a genus of extinct marine gastropod mollusks that lived during the Late Cretaceous period. These creatures are characterized by their highly coiled, conical shells, which are often tightly spiraled and can reach moderate sizes. The shell surface typically displays intricate ornamentation, including prominent axial ribs and spiral sculpture. The aperture, or opening of the shell, is usually ovate and lacks a significant siphonal canal. Fossil specimens of Deviatoida are primarily found in marine sedimentary rocks dating back to the Campanian and Maastrichtian stages of the Late Cretaceous. They are considered part of the extinct superfamily Buccinoidea. The exact taxonomic placement and evolutionary relationships of Deviatoida are still subjects of ongoing research, but they are generally understood to represent an early lineage within the Caenogastropoda. Their shells provide valuable insights into the paleoecology and biodiversity of Cretaceous marine environments.
