Discohoplites subfalcatus Fossil Ammonite Upper Albian Cretaceous Morocco | Genuine Specimen with Certificate

Description

Offered here is a well-preserved Discohoplites subfalcatus ammonite fossil, originating from the Upper Albian Stage of the Cretaceous Period, found in the rich fossil beds of Morocco, North Africa. This rare and attractive ammonite specimen dates to approximately 105–100 million years ago, when much of what is now northern Africa was submerged beneath a warm, shallow epicontinental sea.

The specimen shown in the listing is the exact fossil you will receive, carefully chosen for its scientific interest and display quality. All ammonites are supplied with a Certificate of Authenticity.

Geological & Palaeontological Details:

• Species: Discohoplites subfalcatus
• Fossil Type: Ammonite
• Family: Hoplitidae
• Superfamily: Hoplitoidea
• Order: Ammonitida
• Geological Period: Cretaceous
• Stage: Upper Albian (approx. 105–100 million years ago)
• Location: Morocco
• Biozone: Often found within the Upper Albian ammonite assemblage zones of the Tafilalt region, although exact zone attribution may vary by locality
• Depositional Environment: Shallow marine shelf rich in calcareous and siliceous sediments, supporting a high diversity of invertebrates such as ammonites, bivalves, and crustaceans. Conditions favoured the preservation of calcitic shells and internal moulds.

Morphology & Features:

• Discohoplites subfalcatus is recognised by its flattened, discoidal shell, with strong falcoid (sickle-shaped) ribbing and an involute coiling pattern
• Whorls exhibit pronounced ornamentation with ribs that bend forward toward the venter (outer edge)
• May feature subtle tubercles and a slightly keeled venter, typical of advanced hoplitid ammonites
• The combination of compressed form and delicate ribbing creates a visually striking fossil, both scientifically important and aesthetically appealing

Notability: Discohoplites subfalcatus is a classic Upper Albian ammonite genus originally described by Spath (1923). It is part of a key lineage used in the biostratigraphic correlation of Albian marine sequences across Europe and North Africa. Fossils from Moroccan beds are well-preserved and often studied for their evolutionary significance in Late Albian cephalopod assemblages.
