trying to debunk Selma (Norway's Nessie) and i'm stuck on the 1750 record

so the Seljord serpent. been seeing it spammed as 'PROVEN' on a few pages and i wanted to take it apart because the modern stuff is garbage. the 1998 expedition with the sonar and the egg-trap nets? nothing solid. tourist coat of arms since 1989, basically a town mascot at this point. easy debunk. ……
