A simplified evolutionary tree of predatory dinosaurs (theropods). During the Jurassic, the three-fingered tetanuran theropods appeared, giving rise to birds.

A skeletal reconstruction of Saltriovenator zanellai, made by comparing the shape and proportions of known elements (in orange) with those of more complete skeletons of related species.

An outline map of Italy highlighting Lombardy and the position of Saltrio, the locality where Angelo Zanella discovered the dinosaur now named after him.

At the Natural History Museum of Milan, study authors Cristiano Dal Sasso, Simone Maganuco and Andrea Cau examine the bones of Saltriovenator.

Cristiano Dal Sasso, left, and Angelo Zanella match the shoulder girdle and right forelimb of Saltriovenator with a life-size silhouette of the dinosaur.
