Explain How Cast And Mold Fossils Are Formed. A cast is then formed when the depression is filled by sediment. An animal dies and its body sinks to. Replacement occurs when the original shell or bone dissolves away and is replaced The mineralized impression of the organism left in the sediment is called a mold. A cast shows the external details of a shell or other hard part. Cast and mold fossilization is a process where the original organic material of an organism is replaced or filled in by minerals, creating two distinct fossil. Cast fossils are formed when a mold is filled with sediment that hardens into the shape of the decayed organism, effectively creating a three. Molds form when shells or bones dissolve, leaving behind an empty depression; A mold is a negative impression of an organism, while a cast is a fossil formed when a mold is filled with sediment or mineral deposits. A replica of an organism or a trace such as a footprint or burrow produced by the infilling of a natural mold. Here we go through the five steps of fossilisation to make a typical 'mould and cast' fossil. An animal dies, its skeleton settles on the sea floor and is buried by sediment.
