Popis:

Size comparison of various dinosaurs known from the Huincul Formation. Note that many of these are very fragmentary and necessarily speculative

• Mapusaurus is based on ^[1]
• Meraxes is based on the skeletal in ^[2]
• Skorpiovenator is based on ^[3]
• Ilokelesia is based on Skorpiovenator^[3] and ^[4] and scaled based on ^[3]
• Argentinosaurus is based on my skeletal diagram
• Overoraptor is based on ^[5] with the unknown regions based on Rahonavis^[6]
• Cathartesaura is based on ^[7] with unknown regions based on Limaysaurus.
• Aoniraptor is based on ^[8] with the unknown regions based on Aerosteon^[9] and Australovenator^[10][11]
• Limaysaurus is based on my skeletal diagram
• Gualicho is based on the skeletal diagram by González in ^[12], with unknown parts restored after Deltadromeus^[13], Masiakasaurus,^[14] and, to a lesser extent, Limusaurus^[15]
• The human silhouette is from Silhouette of man standing and facing forward.svg (CC0).
