Anomoeodus is an extinct genus of prehistoric marine ray-finned fish belonging to the family Pycnodontidae. This genus primarily lived during the mid-to-late Cretaceous period, ranging from the Albian to the very end of the Maastrichtian age, and possibly into the Danian.[1][2] The first fossils of Anomoeodus were described by Louis Agassiz in 1833, although they were described under Pycnodus.[1] Some studies have recovered it as a wastebasket taxon.[3]

In the United States, fossil teeth of the widespread species A. phaseolus are colloquially referred to as "drum fish" teeth due to their close resemblance to those of modern drumfish. However, they are unrelated to actual drumfish, which only appeared during the Cenozoic.[4]
