Scale glitching fossils?

Hey all! I was curious if it's possible to scale glitch fossils to be bigger than their max size (just on their own, not on a stand or anything)? A while ago I saw a build with a Leviathan skull around a teleporter, I was going to try and build one myself, but every time I try to scale up any fossil, it just turns into a tiny little cube :') I'm able to scale up every other item no problem, I tried looking online for a workaround or reason why it's not working to no avail. Any insight would be greatly appreciated as I'm relatively new to building techniques like these!
