The presence of the <em>recessus lateralis<\/em> furthermore indicates that the species is a member of the Clupeiformes. Given the absence of odontodes covering the skull bones, which are synapomorphic to the Denticipitoidei, and the apparent presence of a postorbital branch of the supraorbital sensory canal located deep within the body of the lateral wing of the frontal, <em>C. nelsoni<\/em> is assigned to the suborder Clupeoidei. In this suborder, derived character states of the suspensorium indicate that <em>Cynoclupea<\/em> is the sister group of a clade composed of the Chirocentridae (wolf-herrings) and Engraulidae (anchovies). The evolution of abdominal scutes and of microphagy vs. macrophagy in the Clupeoidei are discussed in light of this hypothesis. The discovery of <em>Cynoclupea<\/em> supports not only the existence of a diversified freshwater clupeiform fauna as early as in the Barremian-Aptian, but also indicates that the divergence between the Clupeoidei and Denticipitoidei must have occurred before this interval.Artigo completo:\u00a0<a href=\"https:\/\/academic.oup.com\/zoolinnean\/article\/180\/1\/175\/3799580\">https:\/\/academic.oup.com\/zoolinnean\/article\/180\/1\/175\/3799580<\/a><\/p>\n<\/section>\n<div id=\"attachment_480\" style=\"width: 486px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/www.ufrgs.br\/ictio\/wp-content\/uploads\/2017\/05\/Sin-t\u00edtulo.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-480\" class=\"wp-image-480 size-full\" src=\"https:\/\/www.ufrgs.br\/ictio\/wp-content\/uploads\/2017\/05\/Sin-t\u00edtulo.jpg\" alt=\"\" width=\"476\" height=\"494\" srcset=\"https:\/\/www.ufrgs.br\/ictio\/wp-content\/uploads\/2017\/05\/Sin-t\u00edtulo.jpg 476w, https:\/\/www.ufrgs.br\/ictio\/wp-content\/uploads\/2017\/05\/Sin-t\u00edtulo-289x300.jpg 289w\" sizes=\"auto, (max-width: 476px) 100vw, 476px\" \/><\/a><p id=\"caption-attachment-480\" class=\"wp-caption-text\">Figure 2.
