Vitosaura is an abelisaurid theropod dinosaur that lived in what is now Argentina. It was a medium sized bipedal carnivore reaching around 6 m in total body length. Though only known from the pelvic girdle, Vitosaura likely had a blunt rugose snout, and extremely short arms, as these are typical traits of abelisaurs.

Diuqin is an unenlagiine dinosaur from the Late Cretaceous of what is now Argentina. Unenlagiines, known exclusively from South America, are usually classified as dromaeosaurs though this is sometimes debated. Like dromaeosaurs, they were covered in feathers, carnivorous, and had the large sickle-like claw on the inner toe of each foot. Unique to unenlagiines is their elongated snout, suggesting a piscivorous diet. Diuqin was a medium-sized unenlagiine, at about 4 m in length.
