| Abstract: | Morphology and microstructure of a juvenileAulacoceras, with protoconch, phragmocone and rostrum, are described. External morphology is not very characteristic, so systematical attribution is supported by microstructural data. Moreover rostral growth becomes clear by comparison with adult specimens. |
