[<john-schneiderman@cox.net>]

Boris Sergeyevich Sokolov (Russian) (April 9, 1914 – September 2, 2013) (99 
years old)  was a Russian geologist and paleontologist. Sokolov authored 
reference works on the stratigraphy of Eastern Europe, in particular the fossil 
coral records, and created the concept of Vendian period, currently recognized 
as largely overlapping, but not fully equivalent to Ediacaran.
