Fossils are formed in a number of different ways, but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt. Soft tissues quickly decompose leaving the hard bones or shells behind. Over time sediment builds over the top and hardens into rock. Rhacolepis Buccalis were an extinct form of boney fish. They are one of the few species that have provided palaeontologists with whole fossilised heart specimens, which has aided in the research of the evolution of the heart. The Santana Formation is famous for producing fine fossil specimens and examples of Rhacolepis Buccalii were readily available. They are however now known only through old collections.
