Fossil limestone rock.
Fossil eggs worldwide are very rare. In almost all cases an egg-shaped fossil is something else. Most fossil "eggs" are weathered and rounded rocks, rather than fossils. siderite nodules and concretion s can have smooth, oval shapes and may appear like eggs. Other rocks may be rounded in streams into oval shapes.
