The Tuchengzi represents a poorer, more arid climate that appears to have caused much of the Daohugou fauna to become extinct. They would later be replaced by the Jehol biota when conditions became more favorable to a diversity of terrestrial animal life.[2] Indeterminate sauropod remains formerly attributed to the Mamenchisauridae and Brachiosauridae have been found in Liaoning, China.[3] Theropod tracks, including those made by avialans, have been found in Liaoning, China.[3] {{paleobiota-key-compact}}
