Original price was: £180.00.Current price is: £162.00.

RARE Hybodont Shark Spine Fossil – Oxford Clay Formation – Jurassic: Peterborough, United Kingdom

This listing features a rare Hybodont shark spine fossil from the Jurassic Oxford Clay Formation, discovered in the fossil-rich beds around Peterborough, Cambridgeshire, UK. Hybodonts were extinct cartilaginous fishes related to modern sharks and rays, thriving in Mesozoic seas.

Fossil Type: Shark Spine Element (dorsal or pectoral fin spine)

Species: Hybodontiformes indet.

Order: Hybodontiformes

Family: Hybodontidae

Class: Chondrichthyes (cartilaginous fishes)

Geological Stage: Middle to Late Jurassic (approx. 163–160 million years ago)

Formation: Oxford Clay Formation

Location: Peterborough, Cambridgeshire, UK

Depositional Environment: Shallow marine, low-energy basin with anoxic seafloor conditions ideal for fossil preservation

Morphology Features: This fossilised spine element is typical of Hybodont sharks, which possessed hard, serrated dorsal and pectoral fin spines for defense and possibly hydrodynamic stability. The spine is robust with clear linear ridges and a smooth tapering point, showcasing the durable nature of cartilaginous fish armour. These spines are less common than teeth, making this a sought-after specimen.

Notable: Hybodont sharks were among the dominant shark groups during the Jurassic, and their remains are essential in reconstructing marine food webs of the period. Fossils from the Oxford Clay offer insights into a diverse, well-preserved marine ecosystem that included ichthyosaurs, plesiosaurs, ammonites, and other marine vertebrates.

Condition: The fossil spine is in excellent condition with good detail and natural preservation. Exact specimen shown. Please refer to the photo for scale – Scale Rule Squares / Cube = 1cm.

Important Note:

All of our Fossils are 100% Genuine Specimens & come with a Certificate of Authenticity.

A superb and rare fossil spine from an iconic Jurassic-era shark, perfect for collectors of marine fossils, Mesozoic vertebrates, and cartilaginous fish elements.

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.
