Apparently I'm not finished with this concept yet. Here we go with the home game edition! If you'd like to play, please message me with your guesses of which mammal skeletons these creatures are based on and a suggestion. Get them all right and I'll draw you a shrinkwrapped mammalsaur (or birdsaur) of your own.

Please no guessing in the comments, for obvious reasons. If there are a lot of "winners", I'll pick three or four favorites to illustrate. You have until Monday: go!

Edit: Thanks for playing! Starting on the top left and moving clockwise, these are swamp wallaby (Wallabia bicolor), wild boar (Sus scrofa), short-beaked echidna (Tachyglossus aculeatus), and three-toed sloth (Bradypus tridactylus).
