locutus9 Posted December 19, 2020 Share Posted December 19, 2020 These are two fossils of the same species collected at the Long Pond Road Site along the Erie Canal in Greece, New York. They are from the middle Silurian Rochester shale. These were collected last winter, and I have since been unable to identify them. Both are no greater than 3cm in length. Some interesting fine detail is visible on the first specimen. The American dime is 1.8cm in diameter. 1 Link to comment Share on other sites More sharing options...

Ken K Posted December 19, 2020 Share Posted December 19, 2020 The circular specimen looks quite like the Bryozoan, Lichenalia concentrica, Hall...or close to this. 1 1 Link to comment Share on other sites More sharing options...

A very distinct possibility! They seem to be very similar in appearance. I trust your judgement more than my own given your long and dedicated work in similarly situated strata. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

I'm curious to know how you would arrive at this being a brach as opposed to the bryozoan suggestion offered by Ken K. ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
