Description
This listing features a rare and authentic fossil heteromorph ammonite: Scaphites equalis, collected from the Lower Cenomanian strata of the Cretaceous Period, at Pinhay, Dorset, United Kingdom. The fossil is beautifully preserved and is presented with a Certificate of Authenticity.
Scaphites equalis belongs to a group of ammonites called heteromorphs, known for their unusual shell shapes that deviate from the classic tightly coiled planispiral forms. It is a member of the:
- Order: Ammonitida
- Superfamily: Scaphitoidea
- Family: Scaphitidae
These ammonites lived during the Lower Cenomanian Stage, approximately 100.5 to 93.9 million years ago, in the early part of the Late Cretaceous Epoch. Fossils from the Pinhay Bay area are part of the Chalk Group and associated sedimentary sequences that represent a warm, shallow marine shelf environment teeming with marine life.
Morphological Features:
- Distinctive heteromorph shell: initial tightly coiled whorls followed by a straight or recurved hook-like section
- Ornamented with strong ribbing and possible tubercles or nodes
- Aperture positioned anteriorly, aiding buoyancy and orientation in the water column
These features suggest a unique mode of life among ammonites, likely involving slow swimming and hovering in the water, possibly near the sea floor.
Specimen Details:
- Species: Scaphites equalis
- Fossil Type: Heteromorph Ammonite Shell
- Geological Age: Lower Cenomanian (Early Late Cretaceous)
- Location: Pinhay, Dorset, United Kingdom
- Depositional Environment: Shallow marine carbonate shelf (Chalk Group facies)
- Order: Ammonitida
- Family: Scaphitidae
