Status Partially disarticulated fragment of an irregular echinoid (presumably a holasteroid or, possibly, a spatangoid).
supposed imbrication of the plates that Fossa-Mancini laid great stress on is probably just an outcome of the partially disassociated nature of the fossil on which this was based. As Lambert & Thiery (1920, p. 401) point out, the specimen is almost certainly an ambital fragment of two interambulacra and an ambulacrum of a holasteroid or spatangoid. It has nothing to do with the echinothurioids, contrary to Fossa-Mancini's original suggestion. [details]
