appeared, predator-prey interactions resulted in more selection pressure. Exceptionally preserved fossil occurrences reveal an increase in ecological complexity over time. Escalation in the number of different modes of life includes the exploitation of a greater range of levels above and below the sediment surface (tiering), as well as diversification of feeding mechanisms and modes of locomoti...
