摘要:In the past, fossil faunas have generally been referred to the continent in which they were first studied. Thus it has been customary to speak of European Silurian or Devonian faunas, or of the North American fauna. This has led to the tacit assumption that these faunas were endemic in those regions,

摘要:During the field season of 1928 an immature Sinanthropus lower jaw specimen (from Locus B) and an adult mandibular fragment (from Locus A) were recovered from the main deposit at Choukoutien~1. Both these specimens have already been described briefly before this Society~2. Preparation

摘要:In the course of the splendid summer trip which we enjoyed in the company of the American Central Asiatic Expedition in 1930, we, P. Teilhard de Chardin and myself, collected in the Late Tertiary Tung Gur basin (near Irdin Manha), some remains of Ochotonidae. Through the kindness of Drs. R. C.

摘要:INTRODUCTION Recently, Mr. T. H. Ting, Geologist of the Sino-Swedish Expedition to the North-west, loaned me for description some Dinosaur material which he had collected. These specimens were secured at a place called Haratologay~1

摘要:1. Altogether about one hundred specimens of coal from 19 different provinces of China proper and two specimens from Mongolia were studied. In quality, these coals vary from lignite to anthracite, and in age they belong to different formations of Tertiary, Cretaceous, Jurassic and Permo-Carboniferous. 2. Four methods of investigation, namely, the thin section, the polished section, the maceration and the etching have been used in the present investigation.3. A great number of vegetable tissues and organs such as parenchymatos cells, stone cells, wood tracheids, scalariform tracheids, bast fiber, bark parenchyma, epidermal cells sometimes with cell contents, cork cells, fungi hyphae, sclerotites, spore exines, pollen grains etc. have been detected in the coals studied.4. One of the exceptionally well preserved wood fibers has been definitely identified to belong to Xenoxylon, an index fossil for upper Jurassic formation. This coniferous wood is now known to be widely distributed in the Mesozoic coal basin of Northern China.5. From the presence of fungi activity in the Tertiary coal a rather dry condition for the coal forming period may be advocated. On the other hand, the usually excellently preserved state of the various tissues in the Palaeozoic coals postulates a contrary condition i.e. a wet surrounding and probably under constant covering of water.

摘要:Recent studies of the Late Palaeozoic floras of China have brought to light a comparatively great number of Pteridosperms with attached seeds. From the Permian of Shansi have been described no less than five species of seed-bearing fronds, whereas the total number of established cases of connexion

摘要:INTRODUCTION Manganese deposits are the most important mineral resources of Chin-hsien. To these manganese fields the author paid a visit of some days in April, 1929. The present paper is a summary of the manganese deposits of
