Help! We found this egg shaped rock in Iowa. Decided to cut it open while cutting geodes to see what was inside. The bottom indent showed a milky bit making us think it could be a geode.
It appears similar to a geode but at the same time looks like an undeveloped dinosaur egg! Take it to a local Rock and Mineral Shop and they should be able to tell you. In any case, it should be very collectible!
The second photo IS the same rock. showing outside and inside in 2 pics. Also, we were on vacation when we founds this and it may have come from Tenn. or KY. Did not take note as very unsure if anything at all.
