Abdounia
Abdounia is an extinct genus of requiem shark which lived during the Paleogene period, and is mainly known from isolated teeth. Abdounia is one of the earliest requiem shark genera, and attained widespread success in North America, Europe, and Africa.
Locations
Fossil Abdounia teeth are known from the Paleogene of Morocco, France, Belgium, Russia, and the United States . In the lower Nanjemoy Formation of Virginia, they are the most common fossil shark tooth. By the end of the Oligocene Epoch the genus is severely reduced, probably due to competition with other Carcharhiniformes like Carcharhinus.
Species
The following are species currently attributed to this genus. Note this may be an under-representation of actual diversity, as living relatives have extremely similar teeth across species.
