Uraloclymenia is an extinct ammonoid cephalopod genus from the Late Devonian, Famennian stage. The type species is Uraloclymenia volkovi Bogoslovskii, 1977
The shell of Uranloclymenia is lenticular, with a narrow umbilicus and usually free of ribs. Constrictions are absent. The suture has a very broad, shallow ventral lobe, a shallowly rounded lateral lobe, an inconspicuous umbilical lobe inside the umbilical seam, and an internal lobe on the dorsum. As for all clymeniids, the siphuncle is along the dorsum.
