Submitter notes: These Bactrities are common in the Arkona shale but rarely are they this complete due to the extremely soft shale. This is very delicate and a few more rain drops would have destroyed this association.

Submitter notes: Here's a specimen of Billingsites with the cyrtoconic phragmocone still attached, which was deciduous and would break off later in life. To the best of my knowledge and from what I can find in the literature, I don't know of any other ascocerids still in matrix, other than this and the others I found. From the Stonington peninsula. Block is about 5 inches wide.
