The Okapi was only recognized as real in the 20th century. Then it was thought to be extinct and those that reported seeing them were treated as deluded idiots. Now practically every decent zoo has one.
I think with all of the unexplored land and the vast 90% of unexplored oceans, when we decide that a report is not reliable because we have not seen it or there is no footage, we are doomed to miss it unless it bites us in our collective trouser seats.
But THAT (OP pic) is a coyote.
Now, ask me how I feel about what science calls "primitive" cultures.
