†Juncitarsus gracillimus Olson & Feduccia, 1980 †Juncitarsus merkeli Peters, 1987 Juncitarsus is an extinct genus of wading birds from the Eocene of the United States and Germany.

A small set of bones were collected in 1946 and 1947 by Charles Lewis Gazin, Franklin L. Pearce, and George F. Sternberg at a locality in the Bridger Formation of Wyoming.

[1] Based on the more completed J. merkeli (SMF A 295), the genus was a long-legged bird with a long, slender bill as seen in stilts.

[7] †Juncitarsus Podicipediformes †Palaelodidae †Harrisonavis Phoenicopterus Phoenicoparrus Juncitarsus is known from both the Bridger Formation of Wyoming and the Messel Pit of Germany dating from the Ypresian to the Lutetian stages of the Eocene epoch.

[1][2] Despite this wading lifestyle, this is actually a derived featured for this genus in respect to later mirandornitheans as it is believed this was required independently between Phoenicopteriformes and Juncitarsus.
