LEPTOTETRAGONITES honnoratianus Fossil Ammonite – Valanginian Stage, Early Cretaceous, Morocco

This rare and scientifically important fossil is a beautifully preserved specimen of Leptotetragonites honnoratianus, an extinct genus of fast-swimming, nektonic ammonites that lived during the Valanginian stage of the Early Cretaceous, approximately 139.8 to 132.9 million years ago. Recovered from the fossiliferous marine strata of Morocco, this specimen offers outstanding preservation and a window into early ammonite diversity.

Fossil Type & Species:

  • Type: Invertebrate Fossil (Ammonite Shell)
  • Species: Leptotetragonites honnoratianus
  • Order: Ammonitida
  • Superfamily: Desmoceratoidea
  • Family: Lytoceratidae (or related Desmoceratidae, subject to classification)
  • Described by: d’Orbigny, mid-19th century

Geological & Stratigraphic Details:

  • Origin: Morocco (exact locality within Cretaceous marine platforms)
  • Geological Stage: Valanginian (Early Cretaceous)
  • Age: ~139.8–132.9 million years ago
  • Depositional Environment: Open marine carbonate platform; calm shallow seas with soft sediment ideal for cephalopod fossilisation
  • Biozone: Lower Cretaceous ammonite-bearing beds, specific zonation not formally assigned for this specimen

Morphology & Features: This Leptotetragonites honnoratianus specimen displays:

  • Slender, planispiral coiling with compressed whorls
  • Low umbilicus and smooth flanks, with some weak growth lines or fine striations
  • Elegant tapering shape, designed for fast swimming in ancient seas
  • Well-defined suture lines if polished or naturally exposed
  • Fossilised in subtle hues of brown, tan, or grey depending on the local mineralisation

Notable: Leptotetragonites is a genus associated with more advanced swimming ammonites from the Lower Cretaceous. Its slender, streamlined shell reflects evolutionary adaptation to active marine life. Fossils from this genus are rarely offered to the public and are important for understanding early ammonite dispersal and morphology.

Specimen Details:

  • Origin: Morocco
  • Species: Leptotetragonites honnoratianus
  • Fossil Type: Ammonite Shell (Invertebrate)
  • Geological Stage: Valanginian, Early Cretaceous
  • Size Reference: Scale rule square = 1cm (see photos for sizing accuracy)

Description

Leptotetragonites Honnoratianus Fossil Ammonite

Fossil Identification

This listing features a Leptotetragonites honnoratianus fossil ammonite from Morocco. The specimen is identified as Valanginian and Cretaceous, placing it within an important interval of Earth history associated with the Early Cretaceous. Its scientific name makes it an appealing addition for fossil collectors, ammonite enthusiasts, geology students and anyone interested in marine fossils.

Geological Context

The Valanginian is a stage of the Cretaceous Period. Ammonites were extinct marine cephalopods that lived in ancient seas and are especially valued in palaeontology because their fossilised shells can help document changes through geological time. As an ammonite fossil, this specimen represents a preserved record of ancient marine life and provides a tangible connection to Cretaceous geology.

Leptotetragonites honnoratianus is a specialised fossil identification for collectors who appreciate named ammonite specimens rather than unidentified decorative fossils. The combination of the Leptotetragonites honnoratianus identification, Valanginian age designation, Cretaceous classification and Moroccan origin makes this piece suitable for educational displays, fossil cabinets, geological collections and natural history décor.

Collector Appeal

Ammonites are popular among collectors because they combine scientific interest with distinctive fossil character. A named ammonite specimen can be used to support learning about fossil identification, stratigraphy, palaeontology and the geological history of marine environments. This fossil may also make a thoughtful gift for a collector of Cretaceous fossils, a student of geology, or anyone fascinated by prehistoric life.

The specimen is supplied as the actual fossil shown in the listing images, allowing you to review its visible presentation before purchase. Full sizing is shown in the photographs. The images are intended to provide a direct view of the item offered and help collectors assess its appearance for display or study.
