Plant Fossil Record Reflects Just Two Great Extinction Events – Open Access

Cascales-Miñana, B., and C. J. Cleal, 2014, The
plant fossil record reflects just two great extinction
events. Terra Nova. vol. 26, no. 3, pp. 195–200.

http://onlinelibrary.wiley.com/doi/10.1111/ter.12086/pdf

"Here we show that the plant fossil record in fact only
provides evidence of two mass taxonomic extinction
events, one through the Carboniferous-Permian
transition, the other during middle-late Permian times."

Open Access Geology Textbook Online

Open Access Geology Textbook Online

For the lay rock and mineral collector, there is
a rather nice open access geology textbook. It
is "Earth's Dynamic Systems Web Edition 1.0" T

http://www.earthds.info/
http://www.earthds.info/TOC.html
http://www.earthds.info/Preface.html

Eric H Christiansen and W. Kenneth Hamblin
obviously put a lot of time and effort into it and
is a good introductory text for the interested
layperson.

Best wishes,

Paul H.
