Cryptospores dominate fossil assemblages
Earliest confirmed micro-fossils from either plants, or charophyte algae relative
Evidence of bryophyte-like spores around 475 Ma (Steeman et al. 2009; Wellman et al. 2003, Shaw and Renzaglia 2004)
Derived from the decay-resistant wall and tetrahedral form which are diagnostic of land plants
