Both myself and Randy Savage have posted ideas about a potentially amazing replacement attraction for Dinorama. His was called Mammoth Falls if I recall correctly, a log flume style attraction similar in thrills to Splash Mountain involving mammoths.
My idea was somewhat similar though I felt it a good idea for the ride to be a bit more tame, but broader in scope than just mammoths as the species (though they'd appear in the attraction). I propose a rename of the entire land from Dinoland to "Prehistoria", a land that celebrates not just dinosaurs but celebrates any kind of extinct animal. I also agree with Randy Savage's proposed expansion to Countdown to Extinction as well as the addition of the Excavator.
My version of the replacement of Dinorama (just the carnival, the rest of the attractions stay) would be called Prehistoria River. Again a boat ride similar to Pirates (including its more tame style of drops), only with a far more massive several story tall show building. Each level would be dedicated to one of many ages of extinct animal life, with the beginning through the end of the level moving through that era and the changes the animals underwent throughout their species' existence (animatronic figures and real sets of course). Each area ends with a drop to the next level to transition the jump from one age to another. The ride would ascend to the very top at first, the top most level would focus on the earlier forms of life on the planet and how they evolved into fish and amphibian types of creatures. The second level would focus on the age of the dinosaurs as well as some of the earlier forms of mammals and birds. The third level would focus on the ice age with creatures such as mammoths, megatherium, and saber tooth tigers. After a final drop the ride ends with a scene back to the present time showing fossils of the many animals showcased in the ride and animatronic figures of people digging and studying these remains.
