Kimbryanodus is a genus of extinct ptyctodontid placoderm fish from the Frasnian of Australia.
[1]These placoderms can be told apart from others due to the large eyes, crushing tooth plates, long bodies, reduced armor, and a superficial resemblance to holocephalid fish.
[2] The fossils occur as small three dimensional isolated plates.
[1] Because of these new specimens the Ptyctodontid grouping got a taxonomic classification, it found that the genus Rhamphodopsis to be the most basal taxa.
[1] They are divided by having the more basal taxa having a median dorsal spine, a simple spinal plate, and a simple V-shaped overlap of the anterior lateral and the anterior dorsolateral plates.
