New insights into Mesozoic cycad evolution: an exploration of anatomically preserved Cycadaceae seeds from the Jurassic Oxford Clay biota

Type: Peer Reviewed Research Paper Journal: PeerJ Year: August 28 2017 Authors: Alan R.T. Spencer​, Russell J. Garwood, Andrew R. Rees, Robert J. Raine, Gar W. Rothwell, Neville T.J. Hollingworth, Jason Hilton DOI https://doi.org/10.7717/peerj.3723 Abstract: Most knowledge concerning Mesozoic Era floras has come from compression fossils. This has been augmented in the last 20 years […]
