British Jurassic 'regular' echinoids

Information faithfully-transcribed from museum labels at the NHM. Some information e.g. ammonite zone has been conservatively-inferred based-upon the locality data, taxon and formation/bed data. This is *not* peer-reviewed or error-checked, so please do check the details!!! The 'other' column details extra things. the 'green' and 'red dots' [on the specimen] I believe are used to indicate where a specimen has been figured in a notable publication. 'vg' is my shorthand for a "verygood" well-preserved specimen. The numbers indicate how many tests there are assigned to that BM specimen number
