Trace fossil classification
Ichnogenus:	†Thalassinoides; Ehrenberg, 1944

Thalassinoides is an ichnogenus of trace fossil (fossil records of lifeforms' movement, rather than of the lifeforms themselves) 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]
