SharkySarah Posted November 4, 2021 Share Posted November 4, 2021 Inherited a fossil collection with minerals and rocks. This was in the fossil section. Not sure what it is or where it came from Link to comment Share on other sites More sharing options...
Rockwood Posted November 4, 2021 Share Posted November 4, 2021 (edited) 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.

ChristineR Posted November 4, 2021 Share Posted November 4, 2021 There is not much there that is diagnostic, but a picture of the other side may show something. 1 Link to comment Share on other sites More sharing options...
abyssunder Posted November 4, 2021 Share Posted November 4, 2021 It looks close to what is called "coprolite from Madagascar". 1 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

abyssunder Posted November 5, 2021 Share Posted November 5, 2021 " 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) 1 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

Rockwood Posted November 5, 2021 Share Posted November 5, 2021 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. 1 Link to comment Share on other sites More sharing options...
