Miospore evolution from the Ordovician to the Silurian.
TLDR
The definition of the term cryptospore is amended to include only spores thought to be produced by embryophytes and to exclude all enigmatic palynomorphs, and cryptospores are included here in the miospore group.About:

The timescale of early land plant evolution
Jennifer L. Morris,Mark N. Puttick,James W. Clark,Dianne Edwards,Paul Kenrick,Silvia Pressel,Charles H. Wellman,Ziheng Yang,Ziheng Yang,Harald Schneider,Philip C. J. Donoghue +10 more
TL;DR: A timescale for early land plant evolution that integrates over topological uncertainty by exploring the impact of competing hypotheses on bryophyte−tracheophyte relationships, among other variables, on divergence time estimation is established.
Journal ArticleDOI
Establishing a time-scale for plant evolution
TL;DR: A post-Jurassic origin of angiosperms and a post-Cambrian origin of land plants are rejected, and it is suggested that the establishment of the major embryophyte lineages occurred at a much slower tempo than suggested in most previous studies.

Early Middle Ordovician evidence for land plants in Argentina (eastern Gondwana)
Claudia V. Rubinstein,Philippe Gerrienne,G. De La Puente,Ricardo A. Astini,Philippe Steemans +4 more
TL;DR: The Argentinean cryptospores predate other cryptospore occurrences by c.

Cambrian to Devonian evolution of alluvial systems: The sedimentological impact of the earliest land plants
Neil S. Davies,Martin R. Gibling +1 more
TL;DR: In this article, a comprehensive review of 144 Cambrian to Devonian alluvial successions documented in published literature was combined with original field data from 34 alluvian successions across Europe and North America.

Origin and Radiation of the Earliest Vascular Land Plants
Philippe Steemans,Alain Le Hérissé,John Melvin,Merrell A. Miller,Florentin Paris,Jacques Verniers,Charles H. Wellman +6 more
TL;DR: A diverse trilete spore occurrence from the Late Ordovician is obtained that suggests that vascular plants originated and diversified earlier than previously hypothesized, in Gondwana, before migrating elsewhere and secondarily diversifying.

A discussion and proposals concerning fossil dinoflagellates, hystrichospheres, and acritarchs, ii.
TL;DR: In 19611, it was suggested that many post-Paleozoic organic microfossils that had been called hystrichospheres are really dinoflagellate cysts, and several nomenclatural changes and taxonomic revisions affecting these fossils are proposed.

Global events and event stratigraphy in the Phanerozoic
TL;DR: The existence of rapid and even catastrophic turnover within the Phanerozoic ecosystems has been discussed at length over the years as discussed by the authors, and this discussion has become even more intensive after the hypothesis of Alvarez, explaining the end-Cretaceous mass extinction as the result of a huge asteroid impact on the Earth.

The microfossil record of early land plants: advances in understanding of early terrestrialization, 1970-1984
TL;DR: The interval from the mid Ordovician to the mid-late Early Silurian is hypothesized on the basis of the abundant and widespread spore records to be one of rapid colonization by founder populations with limited genetic diversity and with life-history strategies that included an ecophysiological tolerance to desiccation and a short vegetative life cycle.

A revision of Ordovician series and stages from the historical type area
TL;DR: In this paper, a revision of the standard chronostratigraphy of the Ordovician of the historical type area in England and Wales is presented, which is a response to the need for more precise definitions of series and stages, especially for practical international correlation.
