However, many of the species we know today did not appear until the Cretaceous period (145 million years ago), when a major radiation occurred. Webfossils frequently have both hard and softer parts preserved. In addition, many soft-bodied organisms that do not usually fossilize are preserved. These factors mean that the fossils from Mazon Creek provide scientists with an extraordinary view of biodiversity 300 million years ago.
