[ tahr-soh-met-uh-tahr-suh s ]

/ ˌtɑr soʊˌmɛt əˈtɑr səs /

the large bone in the lower leg of a bird with which the toe bones articulate, formed by the fusion of tarsal and metatarsal bones.

Origin of tarsometatarsus

First recorded in 1850–55; tarso- + metatarsus

tar·so·met·a·tar·sal, adjective

The greater mass of the bipartite muscle probably makes possible a stronger extension of the tarsometatarsus.

The medial metatarsal depression is large; it is on the medial surface of the proximal end of the tarsometatarsus.

Variation in the Muscles and Nerves of the Leg in |E. Bruce Holmes
The lateral branch of the tendon on the tarsometatarsus is not ossified (true also of some legs of Tympanuchus).

Variation in the Muscles and Nerves of the Leg in |E. Bruce Holmes
The insertion is tendinous on the posterior surface of the hypotarsus and along the posterolateral ridge of the tarsometatarsus.

Myology and Serology of the Avian Family Fringillidae |William B. Stallcup

About midway down the tarsometatarsus this tendon becomes ossified.
