Tragophylloceras Ammonite Fossil Split Nodule Positive Negative Green Ammonite UK Jurassic Coast Dorset Certificate

Original price was: £24.00.Current price is: £19.20.

A beautifully preserved split nodule containing a positive and negative impression of the ammonite Tragophylloceras, collected from the Green Ammonite Beds of the Lower Lias at Golden Cap, near Seatown, Dorset, UK. This striking specimen was discovered on 03 May 2025 by our expert fossil team members Alister and Alison and has been meticulously cleaned, prepped, and treated by Alison.

Tragophylloceras is an elegant genus of Early Jurassic ammonites within the family Arietitidae, known for its smooth, discoidal form and relatively involute coiling. These ammonites are important biostratigraphic markers for the early Sinemurian and are especially desirable when preserved in natural nodules.

Fossil Type: Ammonite (extinct marine cephalopod)

Genus: Tragophylloceras

Geological Age: Lower Jurassic – Sinemurian Stage

Formation: Lower Lias Group – Green Ammonite Beds

Depositional Environment: Formed in a low-energy offshore marine setting with anoxic bottom conditions, the Green Ammonite Beds allowed for exquisite fossil preservation within concretions (nodules). These nodules often split cleanly to reveal both positive and negative fossil impressions.

Morphological Features:

  • Involute shell with smooth, rounded flanks
  • Subtle growth lines and possible faint ribbing
  • Distinct suture lines may be visible in polished or cleaned areas

Notable:

  • Complete split nodule with both halves (positive and negative)
  • Classic ammonite from the world-famous Jurassic Coast
  • Discovered and prepared by our in-house team with full provenance
  • The exact specimen photographed is the one for sale

Authenticity: All of our fossils are 100% genuine natural specimens and include a Certificate of Authenticity. Please refer to the image provided — the scale cube equals 1cm for accurate sizing.

Description

Fossil Identification

This listing is for a Tragophylloceras ammonite fossil presented as a split nodule with both the positive and negative sides. The specimen is identified with the Green Ammonite Beds, Lower Lias, Jurassic Coast, and is associated with Golden Cap, Seatown, Dorset, UK. It offers collectors an attractive geological specimen with a named ammonite identification and a direct connection to one of Britain’s best-known fossil coastlines.

The positive and negative presentation is especially appealing for fossil collectors because it shows the two complementary surfaces created when the enclosing nodule was split. Together, these sides provide a more complete view of the preserved fossil impression and the surrounding matrix than a single fragment alone. The natural split-nodule format also makes this piece suitable for display, study, or inclusion in a collection focused on ammonites, Jurassic fossils, Dorset geology, or British paleontology.

Geological Context

The Green Ammonite Beds form part of the Lower Lias sequence associated with the Jurassic Coast. The Lower Lias is a significant Jurassic geological interval known for fossil-rich marine sediments and preserved ammonites. Ammonites were extinct marine cephalopods with chambered, generally coiled shells. Their fossils are valued both for their scientific importance and for the distinctive forms, patterns, and textures created during preservation in sedimentary rock.

Tragophylloceras is the supplied ammonite identification for this specimen. Its named identification adds interest for collectors who catalogue fossils by genus rather than collecting ammonites only by broad group. The Jurassic Coast setting also gives the specimen strong appeal as a Dorset geological collectible and as an educational example of fossil preservation in Lower Lias material.

Collector and Display Appeal

This split ammonite nodule can be displayed with both matching sides visible, allowing the positive and negative surfaces to be appreciated together. It is well suited to fossil displays, geology cabinets, classroom collections, natural history shelves, and gifts for anyone interested in ammonites or the Jurassic Coast. The combination of a named Tragophylloceras identification, Green Ammonite Beds association, and Dorset locality makes it a distinctive addition to a British fossil collection.

Locality Details

The supplied locality is Golden Cap, Seatown, Dorset, UK, within the Jurassic Coast context. This geographical association makes the specimen particularly relevant to collectors interested in Dorset fossils and the geology of southern England.
