This is from my catalog of Net Treasures, which is eclectic and ranges beyond fantasy writing. If you're looking for exotic beasts that have appeared in the historical record, then this is your stop.

Very old, not having been updated in a year or so, but still being maintained by David Badke, its author. Excellent resource that includes information on stones and plants as well as animals, all tied back to primary sources.
