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

Original price was: £48.00.Current price is: £38.40.

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.

Geological Information:

  • Formation: Cretaceous Marine Deposits
  • Stage: Upper Albian (~107-100 million years old)
  • Location: Analavia, Madagascar
  • Depositional Environment: Shallow marine seafloor with fine sediment accumulation

Fossil Characteristics:

  • Straight-shelled ammonite with distinct ornamentation
  • Well-defined suture patterns and preserved structural details
  • Rare Early Cretaceous specimen from Madagascar
  • Excellent example of ammonite adaptation and evolution

Key Features:

  • Authentic Tuberolechites lechites sp. fossil ammonite
  • Rare and well-preserved specimen from Madagascar
  • From the Alice Purnell Collection
  • 100% genuine specimen with Certificate of Authenticity

Cretaceous Information

The Cretaceous Period (145–66 million years ago) was the final era of the Mesozoic, marked by the dominance of dinosaurs and the rise of flowering plants. It had a warm, greenhouse climate, with high sea levels that created vast shallow inland seas. Marine life flourished, including mosasaurs, ammonites, and rudist reefs, while the land was ruled by iconic dinosaurs like Tyrannosaurus rex, Triceratops, and Spinosaurus. Mammals and birds diversified, and insects thrived. The period ended with the mass extinction event, likely caused by an asteroid impact, wiping out the dinosaurs and paving the way for the rise of mammals in the Cenozoic.
