Back home, the catalyst for the worst biotic catastrophe in the world, the Siberian Traps, don't have much left. 252 million years of erosion have reduced the igneous province to a pale shadow of its former self. Here is the brainstorm for an alternate Earth: imgur.com/NWlj880From 60 to 43 million years ago, a series of flood basalt eruptions plagued the northern hemisphere, covering an estimated original area of eleven million square miles and a volume of four million cubic miles. 40 million years of erosion would mean an altogether different Russian landscape, no doubt, but to what extent? Would we still see vast, singular bands of boreal forests and steppes, or would we expect to see Russia hosting a wider variety of habitats?

Given how destructive the original Siberian traps were how much would be left of life on Earth after v 2? You could see a radically different biosphere to what we're used to. This is coming very shortly, in geological terms, after the devastation that destroyed the dinosaurs - where that was a meteor hit or something else, so just as life is diverging after that hit another one comes along. This could include preventing, advancing or delaying the evolution of a set of primates on the African steppes, presuming they still exist.
Don't know enough about ecologies to really guess what the impact would be on the region displayed, assuming that life develops as OTL. Probably mean the region has a somewhat higher elevation? Although I think much of the eastern part of it is fairly high anyway.
