Phycodes bromleyi Dam, 1990

Diagnosis: Infaunal horizontally bundled burrows arranged in a flabellate pattern; each burrow system consists of 15-30 closely stacked short mud lined tunnels that show delicate annulations; tunnels thicken distally toward the exterior part of the burrow and divide in acute angles from a distinct central "radiation" point at the end of a subhorizontal main tunnel.
