Fossil Roman Posted November 24, 2015 Share Posted November 24, 2015 Camacho Formation, Uruguay I WANT it to be an egg, but of course I know that´s not enough for it to BE an egg. I accidentally broke the tip which allowed it to see a kind of shell forming the outside. I will appreciatte any opinions! Link to comment Share on other sites More sharing options...
Auspex Posted November 24, 2015 Share Posted November 24, 2015 I do not know what it is, but it lacks the texture of eggshell, and the rind is too thick to be eggshell.

Agos1221 Posted November 24, 2015 Share Posted November 24, 2015 I would guess coprolite. Fossil poop, depending on age of strata and location you may be able to identify who done the Do do. Link to comment Share on other sites More sharing options...

This is a possibility, with the rind being a diagenetic artifact.

Fossil Roman Posted November 24, 2015 Author Share Posted November 24, 2015 Maybe some kind of seed? Link to comment Share on other sites More sharing options...

Thanks for the answer, I think the shell is too thick too. Link to comment Share on other sites More sharing options...

Yes, my first thought also (not that my first thoughts are always about poop). Link to comment Share on other sites More sharing options...

oilshale Posted November 24, 2015 Share Posted November 24, 2015 How about part of a crab pincer? Be not ashamed of mistakes and thus make them crimes (Confucius, 551 BC - 479 BC). Link to comment Share on other sites More sharing options...

Rockwood Posted November 24, 2015 Share Posted November 24, 2015 How about part of a crab pincer? Would almost have to be an internal mold. Notice in a zoom of the lower left photo that the composition stays uniform all the way to the outside. Only the color seems to alter. Doesn't it ? I think the 'if you would poke it with a stick first' rule can be applied here. Link to comment Share on other sites More sharing options...
Carl Posted November 24, 2015 Share Posted November 24, 2015 How old is it? I vote for coprolite as well. The "rind" really isn't a problem. These can easily form on certain kinds of coprolites in certain types of environments because of weathering. Link to comment Share on other sites More sharing options...
Ptychodus04 Posted November 24, 2015 Share Posted November 24, 2015 I find shark coprolites that have this effect (although not as significant color differences). The "rind" seems to be too even and consistent for that identification IMHO.

If you zoom on the upper right picture the outside seems to be a distinct layer, more compact and petrified, while the inside looks like a filling, more sedimentary.

Fossil Roman Posted November 27, 2015 Author Share Posted November 27, 2015 I found this picture of a "fish coprolite" which has the same darker rim on the outside. So, I´ll go with coprolite as well! http://www.files.tellmewhereonearth.com/Photos%20Poop/pp329a.JPG Link to comment Share on other sites More sharing options...

Compact and petrified, yes. Shell like, not so pretty much. At least I couldn't find an example that looks like this. Link to comment Share on other sites More sharing options...
