Most often the cementing mineral is calcite, but the brown, iron-bearing carbonate mineral siderite is also common.

This is just one method by which nature produces rocks that resemble eggs. Sedimentary concretions are another common imposter. Concretions often form when some object acts as a “seed” for the deposition and cementation of sequential layers of sediment. On occasion, the matter that initiates the concretion, the “seed,” can be a fossil.
