(mya) which would be far earlier than most extant genera of birds. However, it is uncertain whether ''Tringa edwardsi'' indeed belongs into the present-day genus or is a distinct, ancestral form. The time of the ''Tringa''-'' Actitis''-'' Xenus''-'' Phalaropus'' divergence has been tentatively dated at 22 mya, the beginning of the Miocene; even if the dating is largely conjectural, it suggests that ''T. edwardsi'' does indeed not belong into the modern genus. Molecular dating—which is not too reliable, however—indicates that the diversification into the known lineages occurred between 20 and 5 mya. The fossil record contains species formerly separated in ''Totanus'' from the Early Miocene onwards. Although these are usually known from very scant remains, the fact that apparently

ic ''Tringa'' as well as a putative phalarope are known from about 23-22 mya indicates that the shank-phalarope group had already diverged into the modern genera by the start of the Miocene. The biogeography of living and fossil species—notably, the rarity of the latter in well-researched North American sites—seems to suggest that ''Tringa'' originated in Eurasia. Time and place neatly coincide with the disappearance of the last vestiges of the Turgai Sea, and this process may well have been a major factor in the separation of the genera in the shank-phalarope clade. Still, scolopacids are very similar osteologically, and many of the early fossils of presumed shanks require revaluation. * ?''Tringa edwardsi'' (Quercy Late Eocene/Early Oligocene of Mouillac, France) * ?''Tringa gracilis'' (Early Miocene of WC Europe) – calidrid? * ?''Tringa lartetianus'' (Early Miocene of Saint-Gérand-le-Puy, France) * ''Tringa'' spp. (Early Miocene of Ravolzhausen, Germany – Early Pleistocene of Europe)Apparently at least three species at Stránská skála (Czech Republic, Early Pleistocene) for example: Mlíkovský (2002) * ?''Tringa grivensis'' (Middle Miocene of Grive-Saint-Alban, France) * ?''Tringa majori'' (Middle Miocene of Grive-Saint-Alban, France) * ?''Tringa minor'' (Middle Miocene of Grive-Saint-Alban, France) – includes ''"Erolia" ennouchii''; calidriid? * ?''Tringa grigorescui'' (Middle Miocene of Ciobăniţa, Romania) * ?''Tringa scarabellii'' (Late Miocene of Senigallia, Italy) * ''Tringa'' sp. 1 (Late Miocene/Early Pliocene of Lee Creek Mine, USA) * ''Tringa'' sp. 2 (Late Miocene/Early Pliocene of Lee Creek Mine, USA) * ?''Tringa numenioides'' (Early Pliocene of Odessa, Ukraine) * ''Tringa antiqua'' (Late Pliocene of Meade County, USA) * ''Tringa ameghini'' (Late Pleistocene of Talara Tar Seeps, Peru) ''"Tringa" hoffmanni'' is now in ''
