Rare Metriorhynchus Crocodile Tooth Fossil | Jurassic Oxford Clay | Callovian Must Farm UK | Genuine Specimen

Original price was: £78.00.Current price is: £70.20.

For sale is a rare fossil tooth from Metriorhynchus, a fully marine crocodyliform, recovered from the renowned Oxford Clay Formation at Must Farm, near Whittlesey, Peterborough, United Kingdom. This tooth dates to the Callovian Stage of the Middle Jurassic, approximately 166 to 163 million years ago.

Geological & Stratigraphic Context:

  • Formation: Oxford Clay Formation
  • Age: Middle Jurassic (Callovian Stage)
  • Location: Must Farm, Whittlesey, Peterborough, Cambridgeshire, UK
  • Depositional Environment: Shallow marine, low-energy seabed, rich in organic muds and marine vertebrate fossils. The area was submerged under a warm, epicontinental sea during the Callovian, perfect for the preservation of marine reptiles.

Fossil Type & Species:

  • Type: Fossil Tooth
  • Genus: Metriorhynchus (described by von Meyer, 1830)
  • Family: Metriorhynchidae
  • Order: Thalattosuchia
  • Superfamily: Metriorhynchoidea

Morphological Features:

  • Conical tooth with smooth enamel, slightly curved posteriorly, indicative of a grasping and shearing feeding strategy
  • Often lacks pronounced serrations (differentiating from land crocodylians), ideal for holding slippery marine prey like fish and squid
  • Cross-sectional symmetry suggests a streamlined, hydrodynamic morphology consistent with aquatic predation

Notable Details:

  • Metriorhynchus was a fully marine crocodile, unlike modern species—it had paddle-like limbs and a tail fluke, and lacked dermal armour to improve swimming ability
  • The Oxford Clay is a world-famous Lagerstätte for Middle Jurassic marine reptiles, including ichthyosaurs, plesiosaurs, and marine crocodiles
  • Must Farm is one of the most fossil-rich areas of this formation, also known for its archaeological significance

Biozone (If Known):

  • Exact ammonite zonation at Must Farm may include the Quenstedtoceras lamberti Biozone, a standard Callovian marker in southern England

Scale & Specimen Specifics:

  • Scale Rule Squares/Cube = 1cm — please see photographs for exact sizing and proportions
  • The actual specimen shown in the listing photo is the one you will receive, carefully selected for preservation and morphological clarity

 

Certification & Authenticity: All of our fossils are 100% genuine specimens and come with a Certificate of Authenticity. This tooth has been responsibly sourced and offers both scientific and aesthetic value.

 

Own a fascinating piece of marine reptile history with this Metriorhynchus crocodile tooth from the Jurassic Oxford Clay—a striking fossil from the golden age of marine reptiles in Britain.

Jurassic Information

The Jurassic Period (201–145 million years ago) was the golden age of dinosaurs, with iconic species like Brachiosaurus, Stegosaurus, and Allosaurus dominating the land. It was a time of warm, humid climates, with high sea levels that created vast shallow seas, supporting abundant marine reptiles, ammonites, and early coral reefs. The first birds, such as Archaeopteryx, evolved from small theropod dinosaurs, while early mammals remained small and nocturnal. Lush forests of cycads, conifers, and ferns covered the land, providing food for giant herbivores. The breakup of the supercontinent Pangaea accelerated, shaping Earth's geography and setting the stage for the diverse ecosystems of the Cretaceous.
