Number 8 indicates both left and right tarsometatarsus. The tarsometatarsus is a bone that is only found in the lower leg of birds and some non-avian dinosaurs. It is formed from the fusion of several bones found in other types of animals, and homologous to the mammalian tarsus (ankle bones) and metatarsal bones (foot). Despite this, the ...
The ostrich is the only bird that has the didactyl foot. [2] Most birds have four toes, typically three facing forward and one pointing backward. [7] [10] [8] In a typical perching bird, they consist respectively of 3, 4, 5 and 2 phalanges. [2] Some birds, like the sanderling, have only the forward-facing toes; these are called tridactyl feet ...

Magnusavis (meaning "big bird") is an extinct genus of large enantiornithean birds from the Late Cretaceous (Maastrichtian-aged) Hell Creek Formation of Montana, United States. The genus contains a single species , M. ekalakaensis , known from an incomplete right tarsometatarsus and toe bone.
Some sufferers (10–15%) report various pains growing in severity with progression of the disease. [1] The nerves most commonly affected are the peroneal nerve at the fibular head (leg and feet), the ulnar nerve at the elbow (arm) and the median nerve at the wrist (palm, thumbs and fingers), but any peripheral nerve can be affected.
Pigeon skeleton; numbers 10 and 11 indicates the tibiotarsus. The tibiotarsus is the large bone between the femur and the tarsometatarsus in the leg of a bird. It is the fusion of the proximal part of the tarsus with the tibia. A similar structure also occurred in the Mesozoic Heterodontosauridae.
The fifth toe is lost completely except in some birds where it has become a spur. A number of birds have spurs on their feet or legs, usually formed from the lower portion of the tarsometatarsus bone. Best known are the spurs on chicken, though most galliform birds bear spurs. The spurs are mostly found in males, and used in mating competition ...
Kelenken is the largest-known phorusrhacid, 10% larger than its largest relatives known previously. At 716 mm (2.3 ft) long, the holotype skull is the largest known of any bird, and has been likened to the size of a horse's skull. The tarsometatarsus leg bone is 437 mm (17 in) long.
