Description

Stretched tubiform burrows (2-10 mm in diameter), long, straight, sometimes branching, crossing over and interpenetrating; with typical threadlike sculpture, regarded as produced by burrowing activity; interpreted by OSGOOD (1970, p. 380) as "tension faulting" in sole of host rock; appearance depending on kind of preservation. [Originally regarded as marine alga or inorganic; now interpreted as burrows of infaunal origin.] [Found in flysch deposits.]
