Low incidence of atrial septal defects in nonmammalian vertebrates
Evolution &Development, Volume 22, Issue 3, Page 241-256, May 2020., 2020 The atrial septum (arrow) of the African helmeted turtle. There is a low incidence of atrial septal defects in nonmammalian vertebrates. Abstract The atrial septum enables efficient oxygen transport by separating the systemic and pulmonary venous blood returning to the heart.

The discovery of a large ceratodontiform lungfish from the Middle Triassic (Anisian) of Shanxi, China [PDF]
古脊椎动物学报 (中英文版)Ceratodontiformes is the only extant order of Dipnoi (lungfishes). Fossil remains of this group are rare in Triassic deposits in China. Here, we report the recent discovery of a large ceratodontiform lungfish from the Anisian (Middle Triassic ...

Genetic and functional diversity of the multiple lungfish myoglobins
The FEBS Journal, Volume 287, Issue 8, Page 1598-1611, April 2020., 2020 The lungfish harbors multiple copies of the oxygen‐binding protein myoglobin (Mb). Amplification of this gene occurred during an early stage of lungfish evolution. The Mbs are differentially expressed throughout various tissues and display different abilities to bind oxygen or act as enzymes. Remarkably, the main expression site of the Mbs is the brain

Papers in Palaeontology, Volume 12, Issue 3, May/June 2026.Abstract Nearly half of all living vertebrate diversity can be traced back to a single lineage of lobe‐finned fishes (piscine sarcopterygians) that radiated during the Palaeozoic Era. In recent years, the phylogenetic framework of tetrapodomorph fishes has largely stabilized, with the exception of the ‘Osteolepiformes’, the interrelationships of which ...
