F. bidentis leaf was of isobilateral type, and had thicker epidermis cell wall and cuticle, obvious cryptopores, and highly developed palisade tissue, with typical C4-plant Kranz anatomy. The collenchymas and vascular tissue in stem and the aerenchyma in root were well developed. Secretory structure was found in all vegetative organs. According to the analyses of soil physical and chemical properties and relevant ecological factors, F.

Hybrids of carbonate and terrigenous sediments Carbonate with terrigenous sediments are of characteristic from Emsian to Eifelian in stable shallow-sea faciesregion in Longmenshan area, and they can be classified evidently into hybrid Ⅰ and hybrid Ⅱ(Jingbaoshi-type). Type Ⅰ produced in mud shelf setting occupied hundreds of tempestite beds in which bottom cast、 hummocky cross bedding sandstones、 coquina were inter-beddded with shales that beared a great deal of verm traces、 bioturbations、 benthic communities dominative of brachiopods. Type Ⅱ in sand-mud-marl shelf was characterized by high-energy foreshore sandbeach facies and shelly bank facies.
