ptera-j Posted June 5, 2021 Share Posted June 5, 2021 I found this encased in limestone at a dig site in Wisconsin, USA. Its composition seems unusual for anything else at that dig site. It was deep inside limestone and most of the limestone easily pulled off with little effort. Is this an egg? It measures approximately 6.35cm x 4.5cm Link to comment Share on other sites More sharing options...
Thomas.Dodson Posted June 5, 2021 Share Posted June 5, 2021 Not an egg. The center of a limestone concretion with chert replacement. 1 Link to comment Share on other sites More sharing options...
