Abstract: In an investigation of fieldworks in Laoyingshan region in Qijiang District ,Chongqing ,three groups of flute casts were discovered in Upper Cretacious Jiaguan Formation .They were found to be dis‐tributed at the bottom of the sedimentary rock with an elevation of 766-891 m a.s.l. .The stratum devel‐oping flute casts consists of feldspar‐quartz sandstone ,with an underlying layer of mudstone or argilla‐ceous siltstone .The long axis of these flute casts paralleled each other like an echelon arrangement ,with a length varying from 5 to 20 cm ,and the directions of their steep and bulge parts were 25-37° ,indicating that the paleocurrent directions were generally from northeast to southwest in Laoyingshan region in the period of late Cretaceous .T he discovery of these flute casts provides a direct evidence for recovery of pa‐leocurrent direction in Laoyingshan region .
