The paper provides geological description and the results of palynological and carpological studies of natural outcrops of the Koshagach Formation, exposed in the sides of the Samakhinskaya and the Dzhazator depressions in the southeast of Gorny Altai. The deposits are dated to the Early-Middle Miocene. Older layers of the formation corresponding to the Late Oligocene have not been identified.

One new genus and two new species of fossil frog crabs from the Eocene to Oligocene deposits of Washington State (USA) and Vancouver Island (British Columbia, Canada) of the north-eastern Pacific are described, based upon several well- preserved specimens. The studied specimens are herein described as Amphoranina blandi n. gen., n. sp. and A. multispinata n. gen, n. sp. (Raninidae De Haan, 1839) respectively. Amphoranina n. gen. appears to be endemic to the middle to upper Paleogene of the northeastern Pacific.
