Add to ORKGAn entire bouquet of some 250 specimens of Hippuritella vasseuri (DOUVILLÉ) was mapped three dimensionally, based on ascending serial sections spaced at 1 mm, in order to evaluate the earliest ontogenetic development in hippuritid rudists. This method supplied more than 5000 cross-cuts through rudist specimens of different ontogenetic stages beginning from <1 mm larval spat, up to fully grown “senior” rudists. Based on near-commissure cross-sections of all ontogenetic stages, seven characteristic growth stages are distinguished, which show an increasing complexity of morphological features and a change in shell material composition. The complete transformation from a larval settling stage to adult-like morphology happened within the first 8...
