Arenig
In geology, the Arenig (or Arenigian) is a time interval during the Ordovician period and also the suite of rocks which were deposited during this interval. History The term was first used by Adam Sedgwick in 1847 with reference to the "Arenig Ashes and Porphyries" in the neighbourhood of Arenig Fawr, in Merioneth, North Wales. The rock-succession in the Arenig district has been recognized by W. G. Fearnsides (“On the Geology of Arenig Fawr and Moel Llanfnant", Q.J.G.S. vol. lxi., 1905, pp. 608–640, with maps). The above succession is divisible into: # A lower series of gritty and calcareous sediments, the "Arenig Series" as it is now understood; # A middle series, mainly volcanic, with shale, the "Llandeilo Series"; and # The shale and limestones of the Bala or Caradoc Stage. It was to the middle series (2) that Sedgwick first applied the term "Arenig". In the typical region and in North Wales generally the Arenig series appears to be unconformable upon the Cambrian ...

He was left a paraplegic after contracting poliomyelitis at the age of four, but waas able to participate in field excursions. He graduated from the University of Otago with B.Sc. and M.Sc. He received the Hamilton Memorial Prize of the New Zealand Institute in 1926 and a D.Sc. in 1927. His main research interest was marine and non-marine malacofauna of New Zealand, both recent and fossil. He also specialised on fossil Foraminifera. After a long period of unemployment, Finlay was appointed to the Geological Survey of New Zealand in 1937, and in the same year he married Jean Dorothy Waterson Gillies. He was elected a Fellow of the Royal Society of New Zealand in 1939, and was awarded the scoiety's Hector Memorial Medal in 1941.
