Trilobite Feature Identification?

[IonRocks]

I just received my first trilobite, an Asaphus kowalewskii, and noticed indentations on the cephalon near the eye stalks, and would just like to know what it is. I have a few theories, geologic forces (maybe..), the way the trilobite is bent over, or something during the lifespan/non fossilized span of the trilobite. (Or maybe they're just like that?) it was rather difficult to photograph, so I did my best, and if you can't tell, I am referring to the shadowed area at the base of the eye stalk in the upper part of the image.

A very nice first Trilobite.

Yeah, I'm super happy about it, and it was a great price.
