Examples from the Web for dipnoan
The name Dipnoan may, however, be retained as a vernacular equivalent of Dipneusti.
In the archaic tail, enameled scales, and cartilaginous skeleton the Crossopterygian shows its affinity with its Dipnoan ancestry.
It is not unlikely that the Crossopterygian gave rise to Amphibian and Dipnoan alike.
Structurally the amphibian heart closely resembles the dipnoan, though the increased size of the left auricle is an advance.
The dipnoan and ganoid traits one by one are more or less completely lost.
