>>28933221https://en.wikipedia.org/wiki/Relict_(biology)Relict species are a thing. I was a bit surprised when they actually used the concept for mudbray. Relicanth I believe counts as well. In Hawaii, it's usually something simpler like fish, bivalves, monk seals, or coral, but that hasn't stopped gamefreak before. Pic related is technically a relict species for example.
