| B. Schaeffer 1968 | An actinopterygian of problematical affinity, which differs from other taxa within the subclass Actinopterygii by the following combination of characters: Dermal skull composed of many small polygonal bones and several pairs of relatively large irregular ossifications that are extensively overlapped by smaller, radially arranged elements. Dermal bones ornamented with dentine tubercles. Braincase mostly cartilaginous. Parasphenoid broad anteriorly, deeply forked posteriorly, and with large tooth plate covered with minute closely spaced teeth. Ossified basipterygoid process absent. Notochord persistent; centra absent. Ribs ossified. Scales rhomboidal, lepidosteoid, ornamented with crenulated bony ridges. |
