Can anyone identify this for me?

In my opinion that looks like a baby gators head skull hope this helps have a great day

Are you asking about a street map usage  if so here is your answer  a street map for a very limited area could simply be a bit map or a .jpg image.  but a more general map would probably store the streets as vectors.  but you shouldn't assume that there is one way to do it

That's false, when you're born your skull has not fused together yet.
