An ichnoguild of branched, horizontal to slightly inclined burrows or a burrow system, formed by suspension feeders just below water, at the sediment interface. They usually occur in dense associations. The dimensions of the burrows may reflect the environmental energy level. Thalassinoides burrows are typical of clastics and detrital carbonates, and are abundant in certain Jurassic and Tertiary formations. Remains of Bryozoa have been found within them.
