A morphometric approach to conch ontogeny of <i>Cymaclymenia</i> and related genera (Ammonoidea, Late Devonian)
Representatives of the Late Devonian ammonoid family Cymaclymeniidae were studied for their conch ontogeny. Two methods were applied: (1) the analysis of classical morphometric conch parameters and (2) an outline analysis of the aperture using elliptic Fourier analysis. Application of both methods l...

| Summary: | Representatives of the Late Devonian ammonoid family Cymaclymeniidae were
studied for their conch ontogeny. Two methods were applied: (1) the analysis
of classical morphometric conch parameters and (2) an outline analysis of
the aperture using elliptic Fourier analysis. Application of both methods
leads to similar results, allowing a separation of some of the species by
means of their ontogenetic pathways. The new species <i>Procymaclymenia ebbighauseni</i>
n. sp., <i>Cymaclymenia subvexa</i> n. sp.,
<i>Cymaclymenia formosa</i> n. sp., <i>Cymaclymenia lambidia</i> n. sp.,
<i>Cymaclymenia carnata</i> n. sp., <i>Cymaclymenia aulax</i> n. sp.,
<i>Cymaclymenia serotina</i> n. sp. and <i>Postclymenia calceola</i> n. sp. are described in the
systematic part. |
