Age of formations
-Palynomorphs are said to correlate the Tsagayan with the Wodehousia spinata palynozone in NA. Is a Lancian age necessarily implied, or certain?
-If Anchiceratops etc from the lower Horseshoe Canyon are of Late Campanian age, what ceratopsides are now known from the Early Maastrichtian, and from what units?
-Does a Late Maastrichtian age for the Nemegt seem likely now, considering that upper Horseshoe Canyon strata extend into Late Maastrichtian time and some Nemegtian taxa, notably T. bataar , suggest an age intermediate between Horseshoe Canyon and Hell Creek?
-I noticed that Euoplocephalus was not included in the faunal lists for Horseshoe Canyon units. Coombs mentioned Euoplocephalus remains from member B (unit 2?) of the H.C. on 1986. What ankylosaurid remains span the interval between the Late Campanian? H.C. Euoplocephalus and the Lancian Ankylossurus?
-Exactly where were the holotypes of Tarchia and Therizinosaurus found? I think the Soviet expedition of 1948 established a camp at Red Walls.
-How good is the evidence for a late Maastrichtian age for the Javelina? Prof. Williamson cited Tyrannosaurus-like elements as evidence for a Lancian age for the Naashoibito and McRae. Does Javelina material eg TMM41436-1, suggest a smaller, hence earlier tyrannosaur?
