Bandringa? referred specimen (PF8442, Baird 1978, Sallan and Coates 2014; Late Carboniferous) was originally referred to the paddlefish, Bandringa, but the two do not nest together in the LRT. This specimen nests with other basal elasmobranchs, like Falcatus.

Bandringa rayi (Zangerl 1969; Late Carboniferous; PF5686) was considered a tiny shark hatchling, but here nests with the paddlefish, Polyodon. The long paddle is present on this tiny specimen, distinct from extant juveniles of Polyodon (below). The purported dorsal fin is a right pectoral fin.

A referred specimen of Bandringa, PF 8442, nests with the basal elasmobranch, Falcatus.

Cetorhinus maximus (originally Squalus maximus, Gunnerus 1765; Figs. 1, 2) is the extant basking shark, the second largest fish in today's oceans. It is a giant paddlefish, not a shark. The pineal foramen is anterior to the raised frontal (light blue), as in related taxa. Former skull bones are here fused together and turned to cartilage, more so in the adult. In the adult the naris capsule is confluent with the orbit. The nasal (rostrum) in the juvenile curls down in front of the mouth, but rises in the adult to a typical anterior orientation. Gill slits are massive, doubling as plankton collectors. Up to six fertilized eggs are held inside the mother's body for over a year until ready to be born.
