whorls that were distributed along the length of the jaw. This key piece of evidence allowed us to link Qianodus to extinct groups of chondrichthyans, known as acanthodians, that possess whorl-based dentitions.

i.e. we can identify specimens with a left and right labial offset of one of their two primary tooth rows. This is indicative of tooth whorl positions on opposing jaw rami and combined with other evidence suggests that the dentition of Qianodus was formed of closely spaced tooth
