When the scientist isn't sure what an organism or animal is, he or she would then go through all of the questions until they reach the end where the name of the cell or animal would be, or maybe they could find that it is a new discovery.
You will need to find a college instructor that teaches Zoology. Hopefully, you are correct that it is animal and not human.

The first student you are likely to find says he has lost an Animal Skull, pickpocket the Digsite Worker indicated on the map and you will eventually get the skull, return to the student and he will give you the answer to the first question: Earth Science is the study of earth, contents and it's history.
The temporal bone in the skull.
I would expect to find a brain there.
you would probably die, that is if your talking about your real skull not the ones you can find in halo,m the halo skulls cant be shattered

You would find a brain in your skull but do not try to get it because you will kill yourself without skills of a surgeon. Apparently, your brain is NOT in your skull or anywhere in your body if you have to ask where your brain is located.
There are no skull essences
Suture joints are practically immovable joints. You can find them in case of skull. They are there in case of skull, probably to allow the growth of individual bone, in order to increase the size of skull. With out joints, it would be very difficult to increase the size of the skull.
They are useful to scientist, because using the specific description of some organisms the scientist can find out which organisms, like insects, flowers or animals are which. Example: if I give you this descripition, like this animal has hooves, fur, 4 legs, a fur tail and a smooth skin, you can infer that I am talking about a Buffalo. I hope this answer would answer your questions.
