摘要: Vertebrate microremains were collected from the Middle Jurassic freshwater deposits of Lower Member Xietan Formation in Three Gorges area, Hubei Province, People's Republic China. They include remains hybodont sharks (Hybodus aff. “H.” parvidens, Hybodus sp., cf. Parvodus Polyacrodus sp. and Hubeiodus ziguiensis gen. et nov.), an actinopterygian fish, a crocodyliform. The diversity appearance peculiar pattern tooth morphology suggest adaptive radiation these systems China during Jurassic. This diversification led to rich endemic faunas Cretaceous Asia.
