Devonian Period - Fossil Plants, Land Colonization, Evolution: It is now known that some supposedly Silurian plants are actually from the Early Devonian. The Late Silurian record of Cooksonia fossils of the Czech Republic seems to be the earliest unquestionable evidence of vascular plants. Information on spores provided by palynologists would help …Many of the Carboniferous amphibians and anthracosaur groups persisted into the early part of the Permian Period (298.9 million to 251.9 million years ago). The Permian climate became increasing arid, and this change seemed to favour the amniotes, which became progressively more abundant and diverse during this era. Phone. 303-236-1800.

Subsequent research, however, has revealed ...

A global drop in sea level at the end of the Devonian reversed early in the Carboniferous; this created the widespread epicontinental seas and carbonate deposition of the Mississippian. There was also a drop in south polar temperatures; southern Gondwana was glaciated throughout the period, though it is uncertain if the ice sheets were a holdover …The Carboniferous 87 Sr/ 86 Sr record, constructed using brachiopods and conodonts, identifies five phases beginning with a rapid decline from a peak value of c. 0.70840 at the Devonian–Carboniferous boundary to a trough (0.70776–0.70771) in the Visean followed by a rise to a plateau (c. 0.70827) in the upper Bashkirian.Late Devonian time was a period of rapid upheaval in the Earth system, including climate change, sea level changes, widespread ocean anoxia, and the Frasnian-Famennian mass extinction; the cause(s) of these changes remain(s) uncertain.
