Here is a two-ordered meander with simultaneous branching, therefore not a deposit feeder, preserved by turbidity deposition
It is to complicated to be a grazers burrow or deposit feeders fecal matter.  The branching is indicative that the burrows can be revisited by the trace maker.
Two possible functions:
1) trap for meiofauna   2) microbes cultured for food

Graphoglyptid found in Tertiary turbidites, Italy
