Squaloraja

Squaloraja polyspondyla is an extinct chimaeriform fish from the Lower Jurassic of Europe first found by Mary Anning in 1829. Fossils of S. polyspondyla have been found in Lower Jurassic-aged marine strata of Lyme Regis, England, and Osteno, Italy.

Individuals of S. polyspondyla are characterized by their flattened, ray-like bodies, enormous, flattened rostra that comprise half of the bodylength, and, in males, a long, horn-like process.
