Maastrichtian dinobase

  Please note that Edmontosaurus annectens also occurs in the Denver 
Formation, as does Triceratops sp., and Tyrannosaurus rex (Carpenter 
notes)
  I do not know of Edmontosaurus regalis from the Laramie Formation. I 
would appreciate a reference.
  You forgot Edmontonia sp. from the Lance Fm., WY, Hell Creek, SD, and 
MT, and Laramie Fm., CO (Carpenter and Breithaupt JVP 6:251-257).
  Are you sure as to the validity of Paronychodon?
