Geological & Scientific Details:
- Fossil Type: Ammonite
- Species: Graphoceras glevense
- Order: Ammonitida
- Superfamily: Hildoceratoidea
- Family: Graphoceratidae
- Geological Stage: Bajocian (approx. 170.3 – 168.3 million years ago)
- Biozone: Likely within the Humphriesianum or Parkinsoni Zones based on regional stratigraphy
- Period: Jurassic
- Locality: Broadwindsor, Dorset, England, UK
- Depositional Environment: Marine shelf environment within the Wessex Basin — fine-grained calcareous muds and marls deposited under low-energy conditions
Morphology & Notable Features:
- Involute, compressed shell with strong, dense ribbing
- Ribs typically bifurcate from the umbilical edge and continue across the flanks
- Narrow venter with occasional keel present
- Shell shape is discoidal, often with sharp detail in well-preserved specimens
- Ribbing and morphology make this ammonite ideal for identification and stratigraphic placement
Scientific Importance: Graphoceras glevense is a key ammonite species for Bajocian biostratigraphy, aiding in the identification of marine zones within the Middle Jurassic of Europe. It is particularly significant in British and Anglo-Paris Basin stratigraphic studies.
The species was originally described in early Jurassic ammonite monographs and remains a valuable index fossil for correlating Bajocian deposits.
