bitterlily Posted February 2, 2020 Posted February 2, 2020 We were in the creek today and found this Chesapecten Shell that is still closed. We’ve never found one of these with both sides, unopened. Can anyone ID the type of Chesapecten? Is it Madisonious? Thank You!
Ludwigia Posted February 3, 2020 Posted February 3, 2020 I also can't help with id, but that sure is a nice shell. And the gastropod block is also great! Greetings from the Lake of Constance. Roger http://www.steinkern.de/

Shamalama Posted February 3, 2020 Posted February 3, 2020 That is a very nice specimen you have. Can you be more specific with the creek that you were in? The age of the sediments will help with narrowing the ID of the shell. A report from when Chesapectin was established can be found here: https://pubs.usgs.gov/pp/0861/report.pdf Within that report comes this chart 2 -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

cck Posted February 3, 2020 Posted February 3, 2020 The turitella look like part of the Aquia formation, though.... much older.
