This is a partial 'Megaloceros giganteus' jaw I recently bought, which I'd love to learn more about - but especially the following:
1. Is it actually from Megaloceros, or - indeed - another mammal?
2. Can we tell how mature the animal was when it died?
3. Is the jaw a composite at all?
4. How are such fossils prepared for sale after being found: i.e., I'm especially curious to learn about whether paint and/or glue are applied - and, if so, what would it have looked like before such preparation, upon its discovery?
