Thalassinoides

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]
