val horn Posted November 28, 2021 Share Posted November 28, 2021 the hatchling has to be able to hatch. your item has a very thick external "shell"; therefore a hatchling could not hatch, and therefore it is not an egg. it is a concretion which often form layer upon layer. there is a very good discussion of fossil eggs in one of the pinned discussion at the start of the id section. It is well worth reading and looking at the picture. 1 2 Link to comment Share on other sites More sharing options...

Mark Kmiecik Posted November 28, 2021 Share Posted November 28, 2021 (edited) Concretion for sure. Here's one from Illinois, found in the Mazon Creek area. We split them open and there's fossils inside of some. More than 25% percent of them are egg-shaped. This one has a Neuropteris leaf inside. Edited November 30, 2021 by Mark Kmiecik 1 Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
