tyrannosaur teeth and hadrosaur bones



Tyrannosaur teeth from the upper Cedar Mt. formation were referred to Alectrosaurus years ago by Kirkland. Do they most resemble teeth from the Asian tyrannosaur, or Dryptosaurus?

By the way, I came across an old ref that indicates Edmontosaurus bonebeds are known from the Lance formation as well as the Hell Creek. See SVP Abstracts 1995 page 26.
