 One of the specimens , AMZ 6698 , is an adult female that lived in Zürich Zoo . It is represented by a virtually complete skeleton , but the skin was not preserved . According to Schwartz , the skeleton shows signs of osteoporosis and periodontitis ( common in zoo animals ) , but not of other pathologies or abnormalities . The right teeth were removed before Schwartz studied the specimen . Schwartz selected this specimen as the holotype . The other specimen , AMZ @-@ AS 1730 , is a subadult male collected in the wild , of which only the skull , including the mandible ( lower jaw ) , was preserved . The dentition includes both permanent and deciduous teeth . Specimens of Pseudopotto are at least superficially similar to pottos , but according to Schwartz , they differ in a number of traits . Among lorisids , Schwartz saw similarities between the false potto and true pottos as well as angwantibos and slow lorises ( Nycticebus ) . The false potto is comparable in size to the smallest pottos , but falls within their range of metrical variation ; small size is also seen in western pottos .
