GYROCERATITES GRACILIS Fossil Goniatite – Middle Devonian – Germany
£24.00 Original price was: £24.00.£21.60Current price is: £21.60.
This listing features a finely preserved fossil goniatite of the species Gyroceratites gracilis, collected from Middle Devonian strata in Germany. Goniatites are ancient ammonoid cephalopods and are direct evolutionary ancestors to later ammonites.
Fossil Type & Species:
- Type: Fossilised Goniatite (Ammonoid)
- Species: Gyroceratites gracilis
- Authority: Formally described in historical European paleontological literature (specific author uncertain)
Geological Context:
- Era: Paleozoic
- Period: Devonian
- Stage: Middle Devonian (~393–383 million years ago)
- Locality: Germany
- Formation: Likely carbonate or marl-rich marine sedimentary deposits
- Depositional Environment: Warm, shallow epicontinental sea with high biodiversity
Morphological Features:
- Delicately coiled and compressed planispiral shell
- Fine ribbing and suture patterns typical of early ammonoids
- Graceful whorls with narrow cross-sections – indicative of a nektonic lifestyle
Scientific Notes:
- Belongs to a group of early ammonoid cephalopods known as Goniatitida, ancestors of later Jurassic and Cretaceous ammonites
- Valuable for stratigraphic correlation in Devonian marine sediments
- Represents an important transitional form in cephalopod evolution
Taxonomy:
- Order: Goniatitida
- Superfamily: Anarcestaceae (tentatively assigned)
- Family: Unknown / debated (rarely preserved with enough diagnostic detail for conclusive assignment)
Authenticity & Display:
All of our fossils are 100% Genuine Specimens and come with a Certificate of Authenticity. The fossil you see in the photograph is the actual specimen you will receive.
Please refer to the image for full sizing details – scale cube = 1cm.
This is a superb example of an early ammonoid from the Devonian seas, perfect for collectors, educators, and anyone interested in Paleozoic marine life and the origins of ammonites.
