According to a new ScienceDaily article, a huge bone bed of Edmontosaurus and Saurolophus has been uncovered in “southwest Edmonton,” effectively showing that the two species lived side-by-side (there was no evidence to suggest this previously). Likewise, many of the bones bear tooth marks and plenty of teeth from the tyrannosaurid Daspletosaurus have been discovered in the area. The article does not go into much detail about what we can tell from the site (what killed the hadrosaurs, for example), it could be a very interesting example of predators taking advantage of a bonanza after a flood. The taphonomy of this site could certainly give us some clues about how the ancestor of Tyrannosaurus took advantage of such an abundant food source, and I would consider whomever gets to study the site to be lucky. Hopefully I’ll eventually get to visit the Royal Tyrell Museum and other fossil sites in Canada, but I’ve got plenty tying me down in New Jersey for the moment.
