Altispinax

Altispinax (meaning "high spine") was a genus of spinosaurid dinosaur which lived during the early Cretaceous of Europe.

The type species, Altispinax dunkeri (Dames, 1884 and von Huene, 1923), is known only from teeth. Other described species have since been moved to other genera, including Baryonyx. Vertebrae initially linked with the teeth are now known to be from the carnosaur Becklespinax. Thus Altispinax is now usually considered a nomen dubium.
