Priconodon (meaning "saw cone tooth"[1]) is an extinct genus of ankylosaurian dinosaur (perhaps nodosaurid), mainly known from its large teeth.

As an ankylosaur, Priconodon would have been a large armored quadrupedal herbivore, though no size estimation has been done due to the scarcity of described remains.

[3] In 1998 Kenneth Carpenter and James Kirkland, in a review of North American Lower Cretaceous ankylosaurs, considered it tentatively valid as an unusually large nodosaurid, larger than all those described before.

[7] Carpenter and Kirkland (1998) listed 12 additional teeth from the same area as the holotype tooth, and tentatively added a robust tibia (USNM 9154) to the genus.

[8] In 2023, large ankylosaur fossils (including a vertebra and a osteroderms) were announced to be found at Dinosaur Park by John-Paul Hodnett,[9][10] which may potentially represent additional specimens of Priconodon.
