historianmichael Posted June 23, 2021 Share Posted June 23, 2021 (edited) A little over a month ago my dad and I checked out two exposure of the Mifflintown Formation (Late Silurian) in Western PA. While the sites are known mostly for their brachiopods, we ended up finding a couple of other fossils, including several Favosites niaragensis, Hormotoma, and some trace fossils. While I would normally leave the trace fossils alone, I was really awed by the size and appearance of the burrows. I love the bumpiness of the burrows and randomness of their direction. They are almost a work of art. So I decided to take one home. I am not very good at identifying trace fossils though. Are these Planolites?

Rockwood Posted June 23, 2021 Share Posted June 23, 2021 It does fit the basic definition of planolites I believe. I was able to find an example with the finer striations that was so labeled on the web. It may be a distinction made at the ichnospecies level. I do not consider myself an expert in the field however. 1 Link to comment Share on other sites More sharing options...
