I think it’s a fossil

[SharkySarah]

Inherited a fossil collection with minerals and rocks. This was in the fossil section. Not sure what it is or where it came from 

[Rockwood]

It has fossil related look, there probably was a reason that it was collected, but I'm afraid it won't be positively identified as such.

There is not much there that is diagnostic, but a picture of the other side may show something.

It looks close to what is called "coprolite from Madagascar".

"Is called" often means really isn't, however.

"

A new hypothesis for the origin of these so‐called coprolites is proposed, relying on organic‐rich sediment, but inorganic processes. In this scenario, organic‐rich silt and clay was forcefully injected into hollow wood fragments and through knotholes, creating the characteristic features formerly cited as conclusive evidence for the fecal origin of these objects. Diagenetic processes then replaced the organic sediment protected within the wood fragments with siderite. " - (Spencer, 1993)

I could buy that.

Of course, the glue vapors from stabilizing coalified wood, collected for the interesting bore holes, in a small hotel room may be affecting my judgement.
