Hey, If anyone needs any help, please post on talk page. Chalchero Viscacha Rat is the page I'm currently working on. If anyone would like to help they can find a source here []. Thanks for the help! By the way, anyone asociated with the rodent articles should notice that the Plains Viscacha Rat has two articles, Plains Viscacha and Plains Viscacha Rat. They say that the rat is in a different family than the other article.
