It is remarkable that chemically isolated crustoids were usually derived from marly limestones yielding tabulates, bryozoans, brachiopods, annelids, molluscs, pterobranchs and various benthic graptolites. Graptolites were largely planktic, marine organisms, and as one of the first groups that explored the expanses of the world’s oceans are vital for understanding Palaeozoic ecology. They are the best and often the only fossil group for dating Lower Palaeozoic rock successions precisely. Given the distribution pattern, the most favorable habitat for graptolites was over the continental slope and rise. As proposed by Finney and Berry (1997, 1998), building on earlier ideas of Berry et al., (1987), graptolites likely flourished in the denitrification zone at the margins of oxygen minimum zones, which develop beneath zones of upwelling along continental margins.

Unlike their pterobranch kin, which typically live encrusting rocks and shells, most graptolites are thought to have been planktonic, floating or slowly sinking through the water. The spiral shape of some was probably an adaptation to slow sinking. Other graptolites may have been connected to gas-filled sacs, keeping them buoyant. Mode of Life or Habitat: Benthic and sessile filter feeders.
