Fig. 6 in Composite Phymatoderma from Neogene deep-marine deposits in Japan: Implications for Phanerozoic benthic interactions between burrows and the trace-makers of Chondrites and Phycosiphon

Fig. 6. Scatter plots showing the relationships between Phymatoderma burrow diameter and its maximum pellet width (black plot) and reworking trace-fossil diameter. A. Chondrites. B. Phycosiphon. Note that diameters of both ichnogenera that reworked Phymatoderma tunnels are within the size-range of them occurring in the host siltstone (shade), although pellet width increases with increasing Phymatoderma burrow diameter. D Ch, burrow diameter of Chondrites; D Pc, burrow (i.e., central core) diameter of Phycosiphon; D Pm, burrow diameter of Phymatoderma; PW max, maximum pellet width; n, number of measured burrows.
