Origins. Detailed studies have demonstrated that concretions form after sediments are buried but before the sediment is fully lithified during diagenesis. They typically form when a mineral precipitates and cements sediment around a nucleus, which is often organic, such as a leaf, tooth, piece of shell or fossil.Because of the myriad of forms taken by animals and plants, fossils come in countless shapes and sizes. Nearly all of these can be easily recognised, but because Nature is a great imitator, there are several types of rock and mineral structures which are commonly mistaken for fossils.
