NORTHERN ASIA 517
Sikhota-Alin and Vladivostock Area
Along the east coast, from the south side of the Sea of Okhotsk to
Vladivostock, the Jurassic is developed mainly in the Angara facies,
with both plant-beds and volcanics, but in places there are vestiges of
marine incursions of imprecisely determined dates, so far not known to
yield identifiable ammonites. For the most part they are believed to be
Bajocian, with perhaps Bathonian, but near Vladivostock there is probably
also some marine Lias and Lower Bajocian belonging to the Japanese
province. The records of Wittenburg (1909) were shown by M. K.
Eliaschewitsch (now Professor Maxim K. Elias of Nebraska University)
to be in part based on misidentifications of Palaeozoic fossils. The total
thickness of beds assigned by Elias to the Jurassic amounts to 3750 m.
