Nanjinganthus is an angiosperm,isn''''t it?

摘要

Nanjinganthus is an Early Jurassic angiosperm recognized based on the study of over 200 specimens.However,some other authors have misinterpreted these fossils.Here the authors try to remedy the problems,by pointing out the logical pitfalls in these publications and underscoring a long-used,workable criterion for early angiosperms.The paper explains the cons and pros of this criterion,hoping to bring palaeobotany and plant taxonomy back to a consistent and practical track.Nanjinganthus is an angiosperm.
