Subtitled Home of the Somerville Collection. I took a leisurely drive from Orange back to Sydney, and happened to remember this museum in Bathurst. Apparently it has been in operation for quite a while, perhaps since 2004, in an old school building quite similar to the assembly hall at Orange Public, and incidentally, the church down the road where Gonk got married. The town didn't look so different, though almost everyone I knew has moved on, and the number of empty shops waiting for new businesses to spring forth was worrying.
The museum contains a lot of mineral and rock samples, and so would be fascinating to a geologist or chemist, I guess. The fossil collection is relatively small with the highlight being a full size cast of a Tyrannosaurus Rex. It is impressive but also not very integrated with the ambient narrative of slowly evolving life. Something to get the kids in, perhaps.
I probably wouldn't have bothered looking in if it weren't for the nostalgia of loitering in Bathurst for an afternoon.
