A morphometric approach to conch ontogeny of Cymaclymenia and related genera (Ammonoidea, Late Devonian) Author Klein, C. Author Korn, D. text Fossil Record 2014 2014-02-20 17 1 1 32 http://dx.doi.org/10.5194/fr-17-1-2014 journal article 10.5194/fr-17-1-2014 2193-0074 10965299 Procymaclymenia Korn, 2002 Type species: Cymaclymenia inflata Czarnocki, 1989 , p. 67 (original designation (Korn in Korn and Klug, 2002 , p. 220); not “ Cymaclymenia fundifera Czarnocki, 1989 ” as erroneously stated on p. 280). Genus definition: Genus of the Cymaclymeniidae with blunt, slightly asymmetric lateral lobe. Discussion: Procymaclymenia is a genus that closely resembles Cymaclymenia in conch shape, but differs in the less developed lateral lobe. While this lobe in Cymaclymenia is strongly asymmetric and pointed at the ventral side, it is less asymmetric in Procymaclymenia and does not show the acute ventral side. The genus has thus an intermediate position between Genuclymenia (with widely rounded lateral lobe) and Cymaclymenia (with acute lateral lobe). The genus has a much more restricted geographic occurrence than Cymaclymenia . Records are so far only known from the Holy Cross Mountains ( Czarnocki, 1989 ), the South Urals ( Nikolaeva and Bogoslovsky, 2005 ) and North Africa.
