I highly doubt it’s a victim of Cozy Glow. As stated, there are places she could get a skull. Not to mention how old it looks.

@sTs  
If it’s true it would be really fucking badass!

@infinita est lux Solis  
If that’s true, then this would defy g4’s y rating.

@sTs  
Whatever happens, I still believe that that’s one of her parent’s skulls.

@Edhelistar  
I agree, it is indeed (unless the creators of MLP convince us that it’s just some skull she found)

@sTs  
I am disturbed regardless… Killing small animals or pets (Like rodents) is one of the first signs to look for in clinical sociopathy.

@TheMultiBrony21  
It’ll be highly disturbing if that skull is one of her family members.

@TheMultiBrony21  
A rodent’s skull… Like a beaver… or a bunny…

@sTs  
I highly doubt that. Looks more like a relative of Hayseed Turniptruck… Possibly a ancestor.

Oh my God, if that’s her mother’s skull, then she really is a psychopath.

@sTs  
That’s a birds/griffons skull found in the desert.

@TheMultiBrony21  
What about this skull?  

Possibly stole it from Twilight or one of the other classes.
 
I’m sure they have science in the school. Another place she could’ve found it is likely a cave.
