Trace fossil classification
Ichnogenus:	Thalassinoides Ehrenberg, 1944

Thalassinoides is an ichnogenus of trace fossil used to refer to "dichotomously or T-branched boxworks, mazes and shafts, unlined and unornamented".^[1]^:179 Facies of Thalassinoides increased suddenly in abundance at the beginning of the Mesozoic.^[1]^:251 Such burrows are made by a number of organisms, including the sea anemone Cerianthus, Balanoglossus and fishes, but are most closely associated with decapod crustaceans of the (former) infraorder Thalassinidea.^[2]
