Rare baculites fossil ammonite – tuberolechites lechites sp., upper albian, cretaceous, analavia, madagascar – genuine specimen with coa

Description This is a rare Tuberolechites lechites sp. fossil ammonite from the Upper Albian stage of the Early Cretaceous period (~107-100 million years ago), discovered in Analavia, Madagascar. Tuberolechites belongs to the Baculitidae family, a group of straight-shelled ammonites that adapted to open marine environments. Unlike their coiled relatives, Baculites and their close relatives developed a long, uncoiled shell, which allowed for unique buoyancy and movement adaptations. This specimen represents an important evolutionary step in ammonite development and provides valuable insight into Cretaceous marine ecosystems. Fossils from Madagascar are particularly prized for their quality of preservation, making this a highly collectible and scientifically significant specimen.
