Description
Presenting a RARE Mantelliceras lymense ammonite fossil from the Lower Cenomanian stage of the Cretaceous period, unearthed in the fossil-rich region of Sarthe, France.
This well-preserved specimen belongs to the genus Mantelliceras, a group of acanthoceratid ammonites characterised by moderately evolute shells with pronounced ribbing. The genus was first described by S.P. Woodward and includes several index fossils useful in correlating Cenomanian marine strata.
This particular piece features the classic shell profile and ribbed ornamentation typical of the species, making it an ideal example for collectors or educational display.
You will receive the exact specimen shown in the photograph, and a 1cm scale cube is included for precise sizing. All our fossils are 100% genuine specimens and are accompanied by a Certificate of Authenticity.
Geological & Scientific Information:
- Species: Mantelliceras lymense
- Type: Fossil Ammonite (extinct marine cephalopod mollusc)
- Geological Period: Cretaceous
- Stage: Lower Cenomanian (approx. 100.5 – 93.9 million years ago)
- Location Found: Sarthe, Pays de la Loire, France
- Order: Ammonitida
- Superfamily: Acanthoceratoidea
- Family: Acanthoceratidae
- Morphological Features: Moderately evolute shell; broad, rounded whorls; strong, regular ribbing; slightly keeled venter
- Depositional Environment: Shallow marine shelf, part of the expanding Western Interior Seaway during the Cretaceous highstand; composed of calcareous sedimentary facies
- Biozone Association: Often used in correlation with the Mantelliceras mantelli Zone, but M. lymense may be stratigraphically lower, aiding resolution within the Lower Cenomanian ammonite zonation
- Scientific Significance: Mantelliceras species are important index fossils for the Cenomanian and play a key role in stratigraphic correlation of mid-Cretaceous marine sequences in Europe
Additional Notes:
This specimen reflects the evolutionary success of acanthoceratid ammonites during the early Late Cretaceous. The sharp detail and preservation quality add to its scientific and visual appeal.
