Omnivores

Dino-mite Bonapartenykus was one of the carnivore species discovered in South America. Article and fossils, including bones, found in a site in Argentina suggest that the dinosaurs existed between the Campanian Age and the Maastrichtian Age.

Living in the late Cretaceous period, the dinosaurs mostly consisted of adult females who could reproduce eggs. The discovery of two eggs has been identified in an area where the oviduct is supposed to be present.

Eggs were usually placed in a nest to protect them from other species. There has been evidence that the eggs had signs of fungal contamination.

Its lack of skull brings about certain questions, but several scientists have considered the dinosaur as an insectivore. The discovery of strong jaws proves how this dinosaur used to bring the death of small creatures by biting in order to maintain its diet.

Calamosaurus was a small theropod genus of the family Compsognathidae that was first discovered by Richard Lydekker in the Isle of Wight while cataloging the Fox collection.

Despite the lack of comparable material between the two genera, Calamospondylus is often synonymous with it and thus, he attributed the species name 'Calamospondylus foxi', later renamed Calamosaurus foxi in 1891. In addition, he referred to it as the right tibia as similar to a compsognathid, a basal coelurosaur.

The fossil remains were two cervical vertebrae and later a neck vertebra found near Chilton Chine on the Isle of Wight.
