PHYLLOCERAS Fossil Ammonite, Aptian Stage, Cretaceous Period | Genuine Moroccan Specimen + COA

PHYLLOCERAS Fossil Ammonite – Aptian Stage, Cretaceous Period, Morocco

This beautifully preserved Phylloceras fossil ammonite represents an extinct genus of cephalopods that thrived during the Aptian stage of the Early Cretaceous, around 125 to 113 million years ago. Found in the fossil-rich strata of Morocco, this specimen offers a fascinating glimpse into ancient marine ecosystems and the evolution of ammonoids.

Fossil Type & Species:

Type: Invertebrate Fossil (Ammonite Shell)

Genus: Phylloceras

Order: Ammonitida

Suborder: Phylloceratina

Family: Phylloceratidae

Geological Age: Aptian Stage, Early Cretaceous (approx. 125–113 million years ago)

Geological & Stratigraphic Details:

Formation: Likely from Cretaceous marine deposits of the Atlas Basin or adjacent units in Morocco

Depositional Environment: Open marine setting with fine sedimentation that supported the fossilisation of delicate cephalopod shells

Biozone: Aptian ammonite-bearing marine strata (specific zonation not formally assigned)

Morphology & Features: This Phylloceras specimen exhibits the key traits of the genus:

Strongly involute, smooth shell with subtle, fine growth lines

Globular to slightly compressed whorls with continuous outer curvature

No ribs or nodes, unlike many Jurassic or Cretaceous ammonites

Intricate suture lines visible on polished or naturally weathered sections

Fossilised in iron-rich limestone or marl, typical of Moroccan preservation, displaying earthy hues of beige, grey, or brown

Notable: Phylloceras is considered one of the most primitive and long-lived ammonite genera, known from the Triassic through the Cretaceous. Its smooth shell and complex sutures are diagnostic and make it both scientifically significant and aesthetically desirable.
