You might have try about that insaneextinct otterthat live around 6 million age ago and weighed around 11o pounds — about as much as a wildcat . Further enquiry shows its sinewy jaw could have made it a dominant predator .
Last we check off in , scientist wanted to delve profoundly into studying this strange species , Siamogale melilutra . They had a complete skull and mandible specimen — meaning they could study its chomp . And models show this otter had a powerful , shell - jam jaw , one that could have put it atop the food for thought chain .
“ The abundance of aquatic and nigh - water environments in that region , ” swampy waters today site in southwestern China , “ may have allow aquatic carnivorans such as Siamogale to become the predominant predators of their ecological communities , ” the writer write in the study published today in Scientific Reports .
The model began with a complex psychoanalysis of the build and size of it of different otter lower jaw , accept into account the amount of strain they ’d be capable to endure . The researchers figure that other otter jaw ’ severeness scaled with intensity , where smaller otters had firm jaws . It ’s kind of like a light dimmer , where sliding your finger down ( smaller otters ) makes the jaw stronger .
But the model exhibit Siamogale ’s jaw was six time as steady as the first moment , as if you were sliding your finger up and abruptly the lights shut off ( and you got maul by a wolf - sized otter ) . The researchers publishedthis analysistoday in the diary Scientific Reports .
evidently this is an extinct fauna so we wo n’t know precisely what it ate based on the physical body of its jaw alone ( at least not yet ) . Plus , this is just a model , and you may have hear the quote“all theoretical account are wrong but some are utile . ” If its jaw really was this strong , though , it could have done some massive chomping unlike any other otter .
“ Our finding suggest that Siamogale does not have a living analog , but demonstrate limited law of similarity to the living unwritten - crusher Aonyx in having significantly stiffer than ask mandibles among otter , ” the generator compose . Aonyx is a smaller otter specie at only 20 to 50 pounds butcan crushcrab eggshell with its dentition . Now just suppose if it was two to five time larger .
I kind of like the idea of an ecosystem ruled by enormous killer otters , do n’t you ?
