Paleontologists from the Royal Tyrell Museum in Canada have discovered what they're calling the largest dinosaur graveyard near the hamlet of Hilda in the province of Alberta. The bonebed covers nearly a square mile and contains thousands of bones of the ceratopsian dinosaur Centrosaurus apertus, a distant relative of the better-known Triceratops. The discovery is detailed in a new book from Indiana University Press titled, New Perspectives On Horned Dinosaurs. Scientists involved with the study speculate that flooding caused by hurricanes or tropical storms in the Cretaceous Seaway that divided North America killed entire herds of centrosaurs resulting in the large accumulation of their remains.

Thousands of bones suggests tens of animals if each had a hundred.

Interesting: Hilda's altitude is about 2500 ft now.

Antarctica's 90% of the world ice melted could raise our sea level 200 ft. [ http://www.howstuffworks.com/question473.htm ]

The Dec 26 2004 Indian Ocean earthquake generated waves 100 ft high. 'The "Long Island Express" or "Great Hurricane of 1938," a category three, tracked across central Long Island and ripped into southern New England on Sept. 21, 1938, killing nearly 700 people. The storm pushed a 25-35 foot high wall of water ahead of it...' [ http://www.giss.nasa.gov/research/news/20061024/ ]

For the dinosaurs to have died near the Cretaceous seaway (sea level) means that the land must have risen (or that sea levels dropped) quite a lot afterwards.
