The complexity of slightly later [[Gondwana]] plants like ''[[Baragwanathia]]'', which resembled a modern clubmoss, indicates a much longer history for vascular plants, extending into the early Silurian or even [[Ordovician]].{{citation needed|date=September 2016}} The first terrestrial animals also appear in the Wenlock, represented by air-breathing [[millipedes]] from [[Scotland]].<ref name=Selden&Read>{{cite journal |url=http://www.paulselden.net/uploads/7/5/3/2/7532217/seldenread2008.pdf |journal=Bulletin of the British Myriapod & Isopod Group |volume=23 |year=2008 |title=The oldest land animals: Silurian millipedes from Scotland |author=Paul Selden & Helen Read |pages=36–37}}</ref>
