These deposits are at the base of the Pleistocene which is at the more recent age range of this species. This shell form is known from about 60-1.8 million years ago. The exact form of this gastropod is not known but it may have been a predatory species like Natica.
This resin cast of Phacops was produced in 1989 for the Dinosaur Museum, Dorchester by Ancient Art of West Sussex. There is no information with the cast and it has been sitting in the bottom of my fossil cabinet for may years. I suspect it was given to me by someone and I have not made a record of the details. Such a cast is a useful visual addition to a collection, but unless the provenance can be obtained, it has no real scientific value.
There are many fossils that are desirable in a collection, but for some reason they are unobtainable. I have many partial remains of Calymene blumenbachi, including pygidia and cephalon parts, but I do not have a complete specimen. This resin cast of a complete 4.5cm long individual carapace was purchased from the Birmingham City Museum shop some years ago. It is of a specimen in the collections of the museum that was recorded from the Wrens Nest site in Dudley.
