A continuous increase in ichnodiversity occurs through the Ordovician in both shallow- and deep-marine environments. The earlier view that early Paleozoic deep-marine ichnofaunas ...After reviewing @aek post Mystery Fossil of the Upper Cambrian I saw a response by @doushantuo in regards to a rusophycus and it reminded me of a recent plate that I picked up while collecting at St. Leon, Indiana.

Rusophycus avalonensis Zone extends through the balance of the subtrilobite Cambrian and is characterized by the advent of numerous complex burrows, including arthro-pod-produced traces (e.g., Rusophycus, Cruziana, Dimor-phichnus). Crimes (1992b) tabulated at least 25 ichnogen-era that first appear in this interval.Neoichnological study and comparison of these bioturbation structures with the fossil record allow associating them as Cruziana- and Rusophycus-like traces, i.e. traces with features very similar to those of such ichnogenera.
