The purpose of this paper is to illustrate and describe briefly the fossilremains disc(?)vered in 1951 by Messrs.T.Y.Tien and L.M.Yang from theShihchienfeng Series at the Locality Motzekou of Linyu district,N.W.Shensi.The question as to the geological age of this series has given riseto considerable diversity of opinion among geologists and palaeontologists formany years.The discovery of fossil plants from this series is therefore of consi-derable interest.The fragmentary nature of the fossils renders identificationof much of the material difficult and some of it impossible.In spite of this

The purpose of this paper is to illustrate and describe briefly the fossilremains disc(?)vered in 1951 by Messrs.T.Y.Tien and L.M.Yang from theShihchienfeng Series at the Locality Motzekou of Linyu district,N.W.Shensi.The question as to the geological age of this series has given riseto considerable diversity of opinion among geologists and palaeontologists formany years.The discovery of fossil plants from this series is therefore of consi-derable interest.The fragmentary nature of the fossils renders identificationof much of the material difficult and some of it impossible.In spite of this reason the size of the specimens rather then the state of preservation is genreally the chief difficulty encountered. In the meanwhile, it seems desirable to place upon record only those forms which have been determined with a reasonable degree of certainty. The remainder, of which there are a number of indeterminable fragments, will be reserved for a later report.
