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. The group is so far the only Placoderms known with sexually dimorphic features. [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. [1]
