DPS Ammonite Posted June 15, 2020 Share Posted June 15, 2020 It might be barnacle borings, Rogerella. http://www.uky.edu/OtherOrgs/KPS/stratigraphicfauna/sloansvalleymacrofauna/pages/sloansvalleyarthropoda.html 4 My goal is to leave no stone or fossil unturned.

westcoast Posted June 15, 2020 Share Posted June 15, 2020 Looks like the trace fossil Petroxestes possibly made by a boring bivalve. They have been recorded from ordovician, silurian and miocene rocks. 3 Link to comment Share on other sites More sharing options...

abyssunder Posted June 15, 2020 Share Posted June 15, 2020 Unfortunately there are trace fossils not fossils. They are traces made by fossils. We are talking about bioerosion.

abyssunder Posted June 15, 2020 Share Posted June 15, 2020 When the body is not there it will be just a trace of it.
