What is Urosphen?
[[File:Urosphen dubia.jpg|thumb|Fossil]] '''''Urosphen''''' is an extinct genus of prehistoric [[bony fish]] that lived from the early to middle [[Eocene]]. == Description == ''Urosphen'' was slow like ''[[Nardoechelys]]''. Despite its slow movement, it had different ways to attack other [[Fish|fishes]]. # It finds a place where the fish live. # It swims, chases, and hunts the fish. # It preys on the creature and eats it. If it weren't for the extinction of the other [[Prehistoric eel|prehistoric Anguillidae]], you might think that ''Urosphen'' would hunt other [[Fish|extant fish]]. It has a relative from [[Brazil]] and [[Asia]] called ''[[Urosphenopsis]]''. [[Category:Extinct fish]] [[Category:Ray-finned fish]] {{biology-stub}}
