the problem is we have zero remains of aardvarks/anteaters in Egypt, nor any discussion of them being in the area. So it could be, but it could just as well be anything else.
Could it be that someone described an anteater but the artist had never seen one, especially if these are gods of another culture that have been adpoted? There are all sorts of lions, hippos and elephants in medieval illuminated manuscripts that are pretty clearly the result of a telephone game description of the animal.
EDIT: also, wrong tail.
