A ic hypothesis based on 107 morphological characters is proposed for a data set
of 43 taxa. Thirty-three are extant and belong to the orders Zeiformes (20 taxa), Caproiformes
(2), Tetraodontiformes (2), Beryciformes (3), Stephanoberyciformes (3) and Perciformes (3).
Ten are fossil taxa previously assigned to the Zeiformes (3), Caproiformes (1), Tetraodon-
tiformes (2), Perciformes (1), and to two extinct Eocene families, the Sorbinipercidae (2) and
the Zorzinichthyidae (1). This analysis indicates the existence of a previously undocumented
clade formed by the families Sorbinipercidae + Zorzinichthyidae that may be related to the
tetraodontiforms. It also shows that two uppermost Palaeocene species, Archaeozeus skamolensis
and Protozeus kuehnei, sequentially represent the two most basal lineages of zeiforms, whereas
the most ancient known zeiform, the Upper Cretaceous Cretazeus rinaldii, belongs within the
clade of extant species in a polytomy with many other zeiform lineages. A reduced data set of
25 mostly zeiform taxa, after the removal of most outgroups, shows at least weak support for
Cretazeus being nested deeply within the extant zeiforms; such a placement would indicate that
at least six lineages of zeiforms were present during the Upper Cretaceous, and survived the
Cretaceous/Tertiary (K/T) extinction to radiate in Cenozoic seas.
