base notes	DOTTED -- No large tetrapod record in USA Roadian (Base of Roadian ICS Stage; but 'traditional' Roadian spanned uppermost Kungurian and lower half of ICS Roadian => put here as 90% up in Kungurian) or Russia Ufmian (Lucas, 2004, 2013). End of 'classic' sail-backed Early Permian pelycosaur reptiles: 'Olson’s gap is also an evolutionary break between two substantially different global tetrapod faunas. Thus, it is marked by a dramatic remodelling of the Permian tetrapod fauna, from pelycosaur dominated to therapsid dominated.' (Lucas, 2006)				comp notes
