Mold Fossil Formation. Many trace fossils, particularly tracks and burrows, are also either molds or. Molds are imprints left from something that was buried. A cast is then formed when the depression is filled by sediment. 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. When this occurs with permineralization, it is called petrification. Over time, the organism decays, leaving a. The structure decays and its imprint or mold is left in the sediment. A cast fossil, on the other. Replacement occurs when the original shell or bone dissolves away and is replaced by a different mineral; A mold fossil is a negative impression of an organism, formed when the organism itself decays or dissolves. Mold fossils are formed when an organism is buried in sediment, such as sand or mud. Mold and cast fossils exist of all the major types of fossil organisms (invertebrates, vertebrates, and plants). Molds form when shells or bones dissolve, leaving behind an empty depression; Unlike other types of fossils that preserve the actual organic material, mold fossils are formed when the original remains decay or are dissolved by natural.
