Fossiles , shuch as radiolaria etc . , were collected from the strata assigned previously to the carboniferous in the area of danzhou - tunchang in central hainan , now the age of the strata has been determined to be early - mid permian which divided into two parts 摘要在海南岛中部檐州屯昌地区前人划归石炭系地层中采获放射虫等古生物化石，新厘定出一套二叠系地层。
