Txusguy328 Posted June 20, 2018 Share Posted June 20, 2018 I need help identifying this at first look it looks like a cluster of eggs but I’m not quite sure it is very heavy Link to comment Share on other sites More sharing options...
DatFossilBoy Posted June 20, 2018 Share Posted June 20, 2018 Not an egg sorry... You can compare it with dinosaur eggs on google Cool rock though regards Link to comment Share on other sites More sharing options...
abyssunder Posted June 20, 2018 Share Posted June 20, 2018 I don't think they are eggs. It might be botryoidal iron oxide or iron sulfide or more complex mineral. Can we see other sides of it?

DPS Ammonite Posted June 20, 2018 Share Posted June 20, 2018 It is an "egg"nomoly, a pyrite or marcasite nodule. Where was it found and what formation is it from? Texas? It looks like the pyrite nodules found in the Cretaceous Austin Group rocks in Texas. My goal is to leave no stone or fossil unturned.

goatinformationist Posted June 20, 2018 Share Posted June 20, 2018 Scratch test, acid test, scratch plate, and specific gravity all combined would be helpful. Not being jerky, I just collect a lot of rocks. Link to comment Share on other sites More sharing options...

Plax Posted June 21, 2018 Share Posted June 21, 2018 some kind of over pour from the castling/smelting process? If it's very heavy as in "brass" heavy I'd say it is some kind of scrap. We used to get military brass from all over the RR tracks when I was a kid that had spilled from scrap metal hauling hopper cars. The 50 cal brass was the prize. Could be pyrite or marcasite though.

Txusguy328 Posted June 21, 2018 Author Share Posted June 21, 2018 Military brass?? Anything is possible I guess but I doubt it in this part of Texas who knows though Link to comment Share on other sites More sharing options...
DPS Ammonite Posted June 21, 2018 Share Posted June 21, 2018 It is not metal. Try to scratch them with a piece of steel. It will be brittle and not malleable like metal. Also, note the worn crystal faces with angular edges on the nodule which is typical of pyrite. My goal is to leave no stone or fossil unturned.
