Carcharomodus
a.k.a serrated mako,‭ ‬Escher's mako

Name: Carcharomodus ‭(‬jagged similar tooth‭)‬.
Phonetic: Kar-ka-ro-mo-dus.
Named By: Agassiz‭ ‬-‭ ‬1843.
Classification: Chordata,‭ ‬Chondrichthyes,‭ ‬Lamniformes,‭ ‬Lamnidae.
Species: C.‭ ‬escheri‭ (‬type‭)‬.
Diet: Carnivore/Piscivore.
Size: Average body length estimated at up to‭ ‬4‭ ‬meters long.‭ ‬However,‭ ‬isolated remains and differing techniques of establishing body size from teeth have suggested that larger Carcharomodus might have reached‭ ‬4.5‭ ‬or even‭ ‬5‭ ‬meters in length.
Known locations: Atlantic coast regions of North America and Europe.
Time period: Miocene.
Fossil representation: Mostly teeth,‭ ‬but ossified vertebrae are also known.




       Carcharomodus are thought to have been much like modern day mako sharks of the Isurus genus.‭ ‬This is based upon the observation that the overall shape‭ ‬of the teeth of Carcharomodus are almost identical to those seen in mako sharks.‭ ‬The only real clear difference is that the teeth of Carcharomodus are strongly serrated.‭ ‬Whereas modern day mako sharks are very fast swimming predators of fish capable of jumping clear of the surface of the water,‭ ‬Carcharomodus might have been a more generalist predator.‭ ‬This is because the serrations on the teeth of Carcharomodus would have been more suited to cutting up the tough flesh and tissues of marine mammals such as pinnipeds‭ (‬seals‭)‬,‭ ‬and small whales.‭ ‬Strongly serrated are generally‭ ‬unnecessary for fish capture.
       Up until the description of Carcharodon hubbelli,‭ ‬Carcharomodus was thought to have possibly been the missing link between modern great white and mako sharks.‭ ‬Now however it seems that Carcharomodus has‭ ‬no descendants that have survived into modern times.
