A NEW PHYLOGENETIC ANALYSIS AND CHARACTER MATRIX REASSESSMENT FOR THE COELACANTHS (SARCOPTERYGII: COELACANTHIFORMES)

, 2023
3524 pages ; Coelacanths are a lineage of sarcopterygian fishes dating at least to the Early Devonian. They are the extant outgroup to (lungfishes + tetrapods) and are represented by two modern species in the genus Latimeria. Known from fossil material since 1822, coelacanths captured international attention upon the 1938 discovery of a living specimen.

The nanos1 gene was duplicated in early Vertebrates and the two paralogs show different gonadal expression profiles in a shark

Scientific Reports, 2018
Nanos are RNA-binding proteins playing crucial roles in germ cell development and maintenance. Based on phylogenetic and synteny analyses, this study reveals that nanos1 gene has undergone multiple duplications and gene copies losses in Vertebrates ...

Review of Cretaceous dipnoans from Argentina (Sarcopterygii: Dipnoi) with descriptions of new species

Revista del Museo Argentino de CIencias Naturales, 2007
Dans cet article, nous passons en revue les archives fossiles cératodontiformes du Crétacé d'Argentine. Nous rapportons le plus ancien enregistrement de dipnoan d'Argentine, provenant du Cenomanian du nord-ouest de la Patagonie, province de Río Negro. L'espèce « †Ceratodus » iheringi est réassignée. De plus, quatre nouvelles espèces sont décrites.
