However, in 2006 Caron and Jackson concluded that the sea-floor animals were buried where they lived. One of their main reasons was that many fossils represented partially decayed soft-bodied animals such as polychaetes, which had already died shortly before the burial event, and would have been fragmented if they had been transported any significant distance by a storm of swirling sediment. Other evidence for burial where the animals had lived includes the presence of tubes and burrows, and of assemblies of animals preserved while they fed – such as a group of carnivorous priapulids clustered round a freshly moulted arthropod whose new cuticle would not yet have hardened.
