The study, published in the journal Current Biology found the bird's third toe, measuring 9.8 millimetres, is 41% longer than its second toe and 20% than its tarsometatarsus, which is a bone in the lower legs of birds.
They found that the bird's third toe, measuring 9.8 millimeters, is 41 per cent longer than its second toe and 20 per cent longer than its tarsometatarsus, which is a bone in the lower legs of birds.

With the same argument, the relationship between the sum of the tibiotarsus and the tarsometatarsus with respect to the femur is also used to determine how well a cursorial bird is adapted to perform long distance movements (Garland Jr.
We plucked and singed the birds, removed the head, wing tips (cut at the metacarpus and ulna-radius joint), feet (cut at the tarsometatarsus and tibia-fibula joint), and all viscera.
A 2 cm incision was made over the lateral aspect of the left intertarsal joint, and the soft-tissues were bluntly dissected from the distal tibiotarsus and proximal tarsometatarsus. A 30 ga.
A 36 mm segment of the outer gastrocnemius tendon halfway between the origin (from the gastrocnemius muscle complex) and insertion (to the tarsometatarsus) was trimmed to 2 mm width (Figure 1) using a custommade dual blade punch.
Variables measured included body weight, body length (distance from the beginning of the neck to the tail) and shank length (length of the tarsometatarsus from the hock joint to the metatarsal pad).
Many studies are done on chicken with special aspects of leg skeletal development, like knee joint development [24, 25] or development of a certain bone, for example tibiotarsus or tarsometatarsus [9, 28], with only a now-and-then mentioning of other parts of the skeletal system.
We measured length of tarsometatarsus (mean, 61.7 [+ or -] SE 1.9 mm) and distance from tip of beak to front of eye where there was no feather (mean, 61.3 [+ or -] SE 0.7 mm).
Observing that a number of the bird bones were fractured, we carried out a systematic examination of all major wing and leg (tarsometatarsus, tibiotarsus, femur, humerus, ulna, radius) bones for fracture patterns, for remains from TP-5, -6, -10, and -11.
The arrangement is by type of bone, such as coracoid, ulna, femor and tarsometatarsus. This general introduction will be followed by similar volumes focusing more narrowly on specific taxa.
