I'm not sure what exactly your chimeras are based off of, but they look like moose-griffins to me. Not sure if that helps or not. I'm not the best at naming species. I've only named one. ^_^;;
Four of the five bird species in my game will be based on actual mythical birds (Roc, Pamola, Diniao, and Phoenix) so it seemed appropriate to keep those names. The fifth is the Orit (a completely made-up species), and I honestly can't remember how I came up with it. I think I was just throwing sounds together and the people I was talking with about the game at the time really liked that one.
I had a name for the continent at one point, but I don't like it anymore so it's a bit nameless. I actually used Latin for part of many place names and it worked out well. The place names sound cohesive (as if they were named by the same group(s) of people) and due to how I handled the English portion of the place names, it's easy to tell what type of environment the place is. I also used some English (England) place-name prefixes/suffixes to help me in naming certain areas of the map. There's a wiki list somewhere online that I used. The prefixes and suffixes have meaning that help describe what kind of place something is. The list gave examples of how they are used as well.
I wish you the best of luck in finding a naming convention that works for you!!
