This paper systematically studies sporopollen

ostracoda

charophyta and gastropoda of the Linxi Formation in southern Hebei.Sporopollen assemblage of the Linxi Formation is characterized dominantly by gymnospermous pollen

abundance of pteridophytic spores

but no angios-permous pollen are found there.The main members of the assemblage include Schizaoisporites

Cicatricosisporites

Osmundacidites

Densoispoyites

Classopollis Cycadopites and disaccate;Ostracoda:Cypridea (Ulwellia) taihangshanensis

C.(Cy-pridea) unicostata

Damonella extenda

D.ovata

Ziziphocypris linchengensis

Monosulcocypris sp.

Darwinula sp.

Rhinocypris sp.

Charophyta:Mesochara stiptata;Gastropoda:Probaicalia sp.

Brotiopsis sp.Biostratigraphically

the Linxi Formation might be correlated with the Rehe Group in Hebei

the Jiande Group in Zhejiang

the Laiyang Formation in Shandong

the Bayanhua Formation in Inner Mongolia.Geological age of the Linxi Formation may probaply belong to Berriasian-Valanginian period.
