Description
Geology of the Ordovician Period. 

The last Phanerozoic geological period to be named, after a bitter struggle between Murchison and Sedgwick. Lasting from 
485 to 444Ma ago, this period saw the enormous radiation of new forms of life and the earliest colonisation of the land by primitive plants “The Great Ordovician Biodiversification Event” . The two halves of Britain were separated by the Iapetus Ocean, but both were tectonically extremely active. The supercontinent of Gondwana drifted across the South Pole, possibly triggering a short and unusual (high CO2) glaciation and the second biggest mass extinction of life at the end of the period. As usual there is considerable debate about aspects of this period. 

Starts Mon 16th September  for 10 weeks (not 28th Oct nor 4th Nov nor 2nd Dec), until 9th December   Held at Wynstones School, Stroud Road, Whaddon, Gloucester from 7.30-9.30pm on Mondays.
