The Paleozoic emergence of terrestrial plants has been linked to a stepwise increase in
Earth's O 2 levels and a cooling of Earth's climate by drawdown of atmospheric CO 2 …

Recent molecular clock data suggest with high probability a Cambrian origin of
Embryophyta (also called land plants), indicating that their terrestrialization most probably …

Molecular time trees indicating that embryophytes originated around 500 million years ago
(Ma) during the Cambrian are at odds with the record of fossil plants, which first appear in …

Abstract The Ordovician of Scandinavia (ie Denmark, Norway and Sweden) has been
investigated for over two centuries and, through time, various chronostratigraphic schemes …

The abundance, diversity and extinction of non-marine algae are controlled by changes in
the physical and chemical environment and community structure of continental ecosystems …

Terrestrialization probably began more than one billion years ago and irreversibly altered
biogeochemical processes at planetary scale. In this paper, we focus on the terrestrialization …

The origin of land plants is one of the most important evolutionary events in Earth's history.
The mode and timing of the terrestrialization of plants remains debated and previous data …

Because their resistant, sporopolleninous walls preserve a record of morphogenetic change
during spore formation, fossil cryptospores provide a direct physical record of the evolution …

Well preserved palynomorphs from the Hanadir Shale Member of the Qasim Formation
(Darriwilian) from Saudi Arabia were recovered from wells KAHF-1 and TAYM-4, which …

This contribution reviews the evidence for terrestrial organisms during the Ordovician
(microbial, land plant, fungal, animal) and for the nature of the terrestrial biota. The evidence …
