Rare Hemitetagonites crebiscullatum Fossil Ammonite, Lower Hauterivian, Cretaceous, Madagascar – Genuine Fossil with COA

Original price was: £24.00.Current price is: £21.60.

This Rare Hemitetagonites crebiscullatum Fossil Ammonite is an exceptional specimen from the Lower Hauterivian stage of the Cretaceous period, discovered in Madagascar. The fossil is a 100% genuine specimen, accompanied by a Certificate of Authenticity. The Hemitetagonites crebiscullatum ammonite is an intriguing species known for its distinctive shell and unique structure, offering a rare opportunity to own a piece of ancient marine life from the Lower Hauterivian.

Geology and Fossil Type

  • Geological Stage: Lower Hauterivian, Cretaceous
  • Depositional Environment: Marine (The Lower Hauterivian was a time of warm shallow seas that supported a diverse range of marine life, including ammonites such as Hemitetagonites crebiscullatum in regions like Madagascar.)
  • Family: Tetragonitidae (A family of ammonites, characterized by their distinct spiral shape and ribbed, often finely detailed shells)
  • Superfamily: Ammonoidea
  • Order: Ammonitida (Ammonites are part of the Cephalopoda class, related to modern squid and octopus)

Morphology Features

The Hemitetagonites crebiscullatum ammonite features a distinct spiral shape with a smooth yet intricately ribbed surface. The spiral coiling of the shell, along with its well-defined ribbing, provides a unique look at the marine adaptations of this species. The fossil’s suture lines and smooth curvature are indicative of the marine habitat in which it thrived, offering an excellent representation of the ammonite’s role in ancient oceans.

Notable Features

This ammonite is especially notable for its rarity and the fine detail preserved in its structure. The Hemitetagonites crebiscullatum species is not frequently found, making this specimen a rare and highly valuable piece for fossil collectors. Its smooth coiling, coupled with the well-preserved ribbing and suture lines, makes it a standout example of Lower Hauterivian ammonites. This fossil provides a window into the marine ecosystems of the Cretaceous period, making it an important specimen for study and display.

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.
