Trilobite fossils are typically formed through the process of fossilization, where the remains of a trilobite are buried in sediment and over time, the organic material is replaced by minerals. This preserves the trilobite’s form and allows it to be fossilized.Fossils can also form when the remains decay completely but leave an impression in the sediment. Impressions can be of the external shape or internal space (which may fill with other minerals or sediment).Examples include internal impressions of trilobites or ammonites and external impressions of armoured fishes or tree bark.
