The terebratulidine Gonella boucoti gen. et sp. nov. is described from Pragian and Emsian strata of the Selennyakh Range (Northeast Asia). Color patterns are found in both valves, consisting of six radial, dark reddish-brown color bands which begin at the beak, and uniformly expand anteriorly to the anterior margins of the valves. The latter feature, in combination with the character of accompanying megafauna, clearly testify to the presence of a tropical-subtropical climate for this region.
