Hi Paula,

My best guess is that it is the posterior end of an oligochaete. We very often find similar looking fragments of oligochaetes in our benthic samples. It definitely appears to have a digestive tract and the lighter colored areas within  might be ingested sand grains that were being passed through. Anyway, I hope that helps and I'd love to hear what other folks come up with.

Take care,

Dave

Greetings !

I am a graduate student working in Cambrian carbonates in southeastern New York. I found this fossil in a storm deposit in a peritidal sequence. Can anyone help me identify it ?
Thank you so much,
Paula Gural
