Since HT said the Chicxulub asteroid was the specific PoD, I went with this title. It's not the best title, but I want to make it specific enough so as to distinguish it from "Running of the Bulls". I was initially toying with "Intelligent Dinosaurs of North America", since all three stories appear to be set here, but the two POV are of "European/Old World" ancestry, there are native species in the "New World" akin to the Native Americans, and "The Quest for the Great Gray Mossy" introduces a species that parallels Polynesians. A title focusing on geography is probably too specific.
But I'm not going to start creating articles for characters and geography until we've reached a consensus. The template exists, but can be easily moved at this point. That goes out the window when we start creating articles.
