I got a lot of prehistoric things I want to make fakemon for. which actually works out for my Fossil fan type. We got pure Fossil, Fossil/Water, Fossil/Flying, Fossil/Bug, Fossil/Grass, Fossil/Steel, Fossil/Dragon and Fossil/Ice allready.
Let’s see Wooly Rino would be Normal/Fossil, Smilodon could be Fossil/Dark, Deinonychus could be Fighting/Fossil, Gorgonopsid could be Fossil/Poison.
Not all Fossil types would be ancient my Tar pit Ghost/Fossil for example.
