Saltriovenator

Saltriovenator (meaning "Saltrio hunter") is a genus of ceratosaurian dinosaur that lived during the Sinemurian stage of the Early Jurassic in what is now Italy. The type and only species is Saltriovenator zanellai; in the past, the species had been known under the informal name "saltriosaur". Although a full skeleton has not yet been discovered, Saltriovenator is thought to have been a large, bipedal carnivore similar to Ceratosaurus.

==Discovery and naming== thumb|upright|left|Reconstruction of the pectoral girdle and forelimb of Saltriovenator zanellai On 4 August 1996, the first remains of Saltriovenator were discovered by amateur paleontologist Angelo Zanella, searching for ammonites in the Salnova marble quarry in Saltrio, northern Italy. Zanella had already been working for the Museo Civico di Storia Naturale di Milano and this institution after being informed sent out a team to investigate the find. Cristiano Dal Sasso and the volunteers of the Paleontological Group of Besano, under the direction of Giorgio Teruzzi managed to salvage a number of chalk blocks visibly containing bones. The skeleton had shortly before its discovery been blown to pieces by explosives used in the quarry to break the marble layers. Blocks that had been secured were inserted into a bath of formic acid for 1,800 hours to free the bones. Initially, 119 bone fragments were reported to have been collected in total; this was later increased to 132. However, most cannot be exactly identified.
