Here at Walking With Wikis, there is an issue that is still being argued - canon and speculation. Here, we only allow canon.
Canon means information from the show's universe. This means facts that have been disregarded as fact today is fact in the context of the show.
- For example, Arsinoitherium in the canon had hollow horns used to create distinct sounds. Recent scientific research debunks that fact but since the Walking with... said it was fact, we regard it as fact.
Speculation is where people assume facts that are never confirmed in the canon.
- For example, several creatures in the series are unidentified. Assigning them to a real genus or species would be considered speculation.
