I forgot to say I am from Greece so it isn't a lemur
From the front teeth I would say it is a carnivore, as I said in my first post
it looks like a cat but no cat skull I have ever seen has this type of nose intake .
As for the age I unfortunately have no knowledge . I also found an identical skull close to the first which was a little bigger .
Here are some better images of the skull. : http://imgur.com/a/f2CFs
