Description
Offered here is a rare and scientifically significant specimen of Binatisphinctes comptonii, an elegant fossil ammonite from the Callovian Stage of the Middle Jurassic, collected in the historically important fossil site of Christian Malford, Wiltshire, United Kingdom. This carefully selected piece comes from the respected Alice Purnell Collection, and the photo shows the exact specimen you will receive.
Geological Context:
- Species: Binatisphinctes comptonii
- Geological Period: Jurassic
- Stage: Callovian (~166 to 163.5 million years ago)
- Location: Christian Malford, Wiltshire, United Kingdom
- Depositional Environment: Marine shelf setting with intermittent anoxic conditions; the area is renowned for finely preserved fossils from bituminous clays of the Oxford Clay Formation.
Taxonomic Classification:
- Family: Perisphinctidae
- Superfamily: Perisphinctoidea
- Order: Ammonitida
Morphological Features:
Binatisphinctes comptonii is characterised by its finely ribbed, compressed and evolute shell. The ribs are moderately spaced and bifurcate regularly from the umbilical shoulder. This genus lacks strong tuberculation and presents a more streamlined and symmetrical profile compared to other coeval ammonites. This specimen preserves these diagnostic features in beautiful detail.
Biozone and Notability:
This species is frequently associated with the Jason Zone of the Lower Callovian. The Binatisphinctes genus is used in regional stratigraphy and is notable for its occurrence alongside exceptionally preserved soft-bodied fossils in the Christian Malford Lagerstätte, one of the UK’s most iconic Jurassic fossil localities.
