拍品专文
Still veiled in mystery, the evolutionary benefit of the unrolled form is not yet fully understood. It is possible that this species inhabited the benthic zone and therefore did not need a form suitable for swimming. A spiky shell would therefore have been necessary to protect an animal moving slowly on the seabed.

In excellent overall condition. An old tinkered break from excavation to the ammonite since restored, some spikes blunted, others reattached, as commonly seen.
