Description
Offered here is a rare and scientifically valuable fossil ammonite, Proscaphites anar, from the Upper Oxfordian stage of the Late Jurassic, collected in Deux-Sèvres, France. This fossil represents an exceptional example of Jurassic ammonoid evolution from the northwestern margin of the ancient Tethys Ocean.
Proscaphites anar is a relatively rare genus known for its distinctive morphology, including:
- Compressed, involute coiling with a narrow umbilicus
- Finely ribbed ornamentation, sometimes showing subtle tuberculation
- A shell shape transitioning between planispiral and lightly heteromorphic tendencies in later ontogeny
- Species: Proscaphites anar
- Order: Ammonitida
- Superfamily: Perisphinctoidea
- Family: Unknown or debated (due to rarity)
- Geological Stage: Upper Oxfordian, Late Jurassic
- Location: Deux-Sèvres, France
- Depositional Environment: Shallow marine carbonate shelf, Tethyan margin
- Biozone: Likely within Perisphinctes or Gregoryceras zones (Upper Oxfordian)
Estimated at around 157–155 million years old, this ammonite reflects the morphological experimentation typical of the Oxfordian age. Its rarity and striking preservation make it a prized specimen for collectors and researchers alike.
