Hi, @james-beech – Is it possible this is Astarte concentrica: https://neogeneatlas.net/species/astarte-concentrica/
Check out the images tab on that link. If you upload another image of the interior of the shell we can work to narrow in on the taxonomy.
Here is a link of the geologic context for the Aurora area: https://macrostrat.org/map/#/z=10.9/x=-76.7666/y=35.3209/bedrock/lines/ that should help with the type of rock depending on where you were collecting.
Talk to you soon, Jen
