Description
This is a rare Tuberolechites lechites sp. fossil ammonite, dating to the Coniacian stage of the Late Cretaceous period (~89-86 million years ago), discovered in Carrollton, Texas, USA. Tuberolechites is a genus of straight-shelled ammonites, part of the Baculitidae family, which adapted to open marine environments. Unlike traditional coiled ammonites, Tuberolechites developed a long, uncoiled shell, allowing for improved buoyancy and hydrodynamic efficiency in ancient seas.
This specimen comes from the Bitton Formation, a well-documented Late Cretaceous marine deposit known for its exceptional ammonite and marine reptile fossils. This Baculites fossil provides important insights into Cretaceous marine ecosystems and is a valuable piece for both collectors and researchers.
