Morphological links in an evolutionary sequence of the Cretaceous ammonite genus Metoicoceras Hyatt

Abstract:

Species of the ammonite genus Metoicoceras are not generally strongly differentiated with respect to coiling and ornament. The present study addresses the problem of how well purely visual (subjective) identification succeeds in identifying taxonomically and hence evolutionarily relevant differences between forms. Multivariate statistical analysis, based on coiling, standard dimensions of the conch and ornamental properties, indicates that quantitative procedures reproduce traditional methods...
