Skorpiovenator ("scorpion hunter") is a genus of abelisaurid theropod dinosaur from the Late Cretaceous (Cenomanian to Turonian) Huincul Formation of Argentina.

The sole species of Skorpiovenator, S. bustinggoryi, was named in honour of Manuel Bustingorryi, the late owner of the farm on which the type specimen was discovered.

The type specimen of Skorpiovenator bustingorryi (MMCH-PV 48K) was discovered on a farm owned by Manuel Bustingorry, 3 km (1.9 mi) northwest of Villa El Chocón, in the Neuquén Province.

The strata from which Skorpiovenator was recovered belong to the lower part of the Huincul Formation in Patagonia, dating to the late Cenomanian stage, about 95 million years ago.

In a paper physically published in 2009 (released as an advanced publication online the year before), Juan Canale, Carlos A. Scanferla, Federico L. Agnolin and Fenando E. Novas formally described the specimen, assigning to it the binomial name of Skorpiovenator bustinggoryi.

Since it lacks most of the tail, precise length measurements are currently impossible, but it has been estimated to have grown up to 6–6.2 m (19.7–20.3 ft) long and weighed up to 891 kilograms (1,964 lb).

[10] The cnemial crest was very large, and the ilia had deep preacetabular and postacetabular blades, suggesting that, as in other ablelisaurids, the muscles that extended and flexed the legs were very powerful.

In their results, they found that all South American forms (including Skorpiovenator) grouped together as a sub-clade of Carnotaurinae, which they named Brachyrostra, meaning "short snouts".

A study of the El Zampal section of the formation found hornworts, liverworts, ferns, Selaginellales, possible Noeggerathiales, gymnosperms (including gnetophytes and conifers), and angiosperms (flowering plants), in addition to several pollen grains of unknown affinities.

[17] The Huincul Formation is among the richest Patagonian vertebrate associations, preserving fish including dipnoans and gar, chelid turtles, squamates, sphenodonts, neosuchian crocodilians, and a wide variety of dinosaurs.
