Squaloraja

Squaloraja (Latin for "shark-skate") is an extinct genus of ray-like marine chimaeriform fish from the Early Jurassic of Europe.

[1] It contains a single named species known from the Sinemurian-aged Blue Lias of Lyme Regis, England: S. polyspondyla Agassiz, 1836, with complete specimens representing both males and females.

A second species from the same locality, S. tenuispina Woodward, 1886 (known from an isolated horn of a male), is now considered conspecific with S.

Males had a cephalic clasper extending out from just above the rostrum that resembled a long, horn-like process.

The taxon was first described as Squalo-raia dolichognathos by Henry Riley in 1833 based on Anning's specimen, who identified it as a chondrichthyan with features of both sharks and rays, but this description was not publicly released until several years later.
