| Summary: | Serial grinding and three-dimensional reconstruction of aff. Parahaentzschelinia trace fossils from the Ordovician Winterhouse Formation reveals complex tiered network systems associated with more typical Parahaentzschelinia-like conical bundles of sub-vertical tubes. The morphological complexity of the burrow system is interpreted as an indication of the diverse behaviour of the trace-making organism. This organism is inferred to have exploited organic matter within the sand-rich event beds as well as in muddier beds above and below the sandstone beds using a variety of behaviours. Potential burrow irrigation and microbial cultivation associated with gardening behaviour is also inferred. The trace-making organism is unknown, but comparisons are drawn between the structures observed herein and those produced by both modern polychaetes and bivalves. clip through network-like portionThe animation shows the movement of a clip plane orientated parallel to bedding documenting the network or Multina-like portion of the aff.
