Are you also a collector perhaps?
As a Geologist, I have been known to pick up a rock or three from time to time. Mostly I have rock & mineral specimens from my field work, and not generally museum quality material such as you have, but rather sample/assay grade stuff.
Back in my college days, I was required to put together something of a fossil collection that I had all gathered myself, but it mostly consisted of nondescript corals, a few brachiopods, some asymmetric bivalves, trilobite fragments, some crinoid stems and likely a few others that I'm not remembering just now. Beyond that I do have a few sharks teeth, a mammoth tusk laminate and some giant ground sloth feces. Well, technically that last one isn't a fossil, even though it is from a wholly extinct species, but was preserved in dry desert air in a cave at the lower end of the Grand Canyon, which seems to have been this creatures den back in the Pleistocene. I have almost nothing on display, but rather most of it is in sample bags stored in ammo cans and 5 gallon buckets, a couple of collectable aviation gas can boxes (but that's another story) as well as just scattered around out in the yard.
