£ 60.00
A rare and scientifically important Hemitetagonites crebiscutatum Fossil
Ammonite, from the Albian Stage of the Cretaceous Period, collected in Madagascar. This unusual ammonite represents a distinctive genus with striking ribbing patterns, making it a superb specimen for collectors of rare Cretaceous fossils. The exact specimen shown in the photographs is the one you will receive, and it comes with a Certificate of Authenticity.Fossil Type & Species:
• Type: Ammonite (extinct marine cephalopod)
• Species: Hemitetagonites crebiscutatum
• Order: Ammonitida
• Superfamily: Acanthoceratoidea
• Family: BrancoceratidaeGeological Context:
• Period: Cretaceous
• Epoch/Stage: Lower Cretaceous – Albian (approx. 113 to 100.5 million years ago)
• Biozone: Often associated with mid- to late-Albian ammonite assemblages used for zonal correlation
• Depositional Environment: Shallow epicontinental seas with fine calcareous sediments, favourable for ammonite fossilisationLocality:
• Region: Madagascar (exact formation not specified, but part of Madagascar’s well-known Albian marine fossil deposits)Morphology & Features:
• Moderately evolute shell with a wide umbilicus
• Strong ribbing, often crowded and branching, extending continuously across the venter
• Robust, discoidal whorls with well-marked ornamentation
• Distinctive high rib density gives the species its recognisable appearanceScientific Notes:
• Hemitetagonites crebiscutatum was first described by Stoliczka (1863) during his pioneering work on Cretaceous ammonites of southern Asia, later identified in Madagascar deposits
• It is considered a key ammonite species for correlation within the Albian stage across the Tethyan realmNotable Details:
• Excellent preservation of ribbing and overall shell form
• Completely natural, unrestored specimen
• Scale Reference: Each square or cube in the photo = 1cm. Please see images for accurate fossil dimensionsAuthenticity & Guarantee: All of our fossils are 100% genuine, responsibly sourced, and professionally curated. A Certificate of Authenticity is included with your purchase. The fossil shown is the exact specimen you will receive. This Hemitetagonites crebiscutatum ammonite is a rare and scientifically valuable fossil from Madagascar, making it a perfect addition to advanced collections or natural history displays.
