Egg? Probably just a rock though
I was hoping it was an egg.
Hi @diane-soderman this might just be a sedimentary rock. Do you have any more specific location information? This can help with ID!
Beadle or Kingsbury County South Dakota. we had 7 1/2 inches of rain & creeks flooded & took out roads.
Greetings@diane-soderman ! I agree with @mackenzie-ross-2 about those being a sedimentary rock. Also, if you are in Kingsbury County then you are in the Pierre Shale Formation. The Pierre Shale covers most of eastern SD and in primarily marine late Cretaceous sediments. Ferruginious nodules, like the one you found, are common in the PSF. I have collected specimens from the Pierre Shale from Dawes County, NE if you would like a comparable reference to the types of fossils from the formation.
