Or, Mokuy gets dinosaurs
“Giant lizard, small dinosaur or feathered reptile?
There have been conflicting descriptions of this giant reptilian Indigenous cryptid, but documented sightings from the 1950s to the late 1980s describe the creature as walking on two legs – akin to a 20th-century tyrannosaurus rex.”

So of course if it could be seen in 1950, it could be seen in 1800!
Above article also has the ferocious drop bear, of course.
