Select from the options above.

Correct Option: 4  

Explanation:
Birds
The tarsometatarsus is formed from the fusion of the distals and three of the metatarsals found in the feet of other animals. It is seated between the "ankle" and the digits of the foot, and gives the leg extra length and leverage. The bone has also been found in a group of tiny ornithischian dinosaurs from the Late Triassic unrelated to birds.
