SVP Memoir's A. olseni age




Is a Campanian age really the most up to date and accurate estimate for the Iren Dabasu formation and Alectrosaurus? IIRC Currie only said that Iren Dabasu was post Cenomanian, or Turonian to Campanian. In 2001 Kikland and Wolfe wrote that similarities between a North American therizinosaur and Segnosaurus and Erlicosaurus could help resolve the age of the Baynshirenskayasvita "as closer to Turonian than Campanian". And IIRC, the Baynshirenian beds of Burkhant are considered to lie within the pre-Campanian Cretaceous long normal.
