Sometimes the strangest things you hear about in cryptozoology catch up with physical evidence years later. Take, for instance, Killer Kangaroos. No, I’m not talking about the Mystery Kangaroos that punched out the Chicago police in the 1970s. I’m thinking, instead, about the Killer Kangaroo of 1934.

This week saw news out of Australia that “killer kangaroos,” “demon ducks of doom,” and eighteen other previously unknown species had been discovered by paleontologists at a dig site in Queensland, northern Australia.

The new animals’ tags immediately made me think of the names I’d coined or heard before in cryptozoology. Who couldn’t love the “demon ducks of doom.” Obviously, someone in Australia is showing a love of the “d” sounds of alliteration for that one, just like I did when I gave the moniker to the “Dover Demon,” which was sighted in 1977, in Massachusetts.

Paleontologist Sue Hand reported that during the dig that they found some very big birds — more like ducks — to which they gave the name “demon ducks of doom.” She said some may have been carnivorous. Obviously.

In those same Riversleigh fossil fields, the University of New South Wales team was also uncovering evidence of a “killer kangaroo,” a flesh-eating marsupial, from 10 to 20 million years ago.

Professor Mike Archer said that among the new species discovered “were meat-eating kangaroos with long fangs and galloping kangaroos with long forearms, which could not hop.”

This, needless to say, reminded me of the cryptid Killer Kangaroo of 1934, which I had researched in old newspaper archives some 30 years previous.

As I wrote in Mysterious America, reports of giant kangaroos are nothing new to cryptozoology. Over seven decades ago, the notorious “Killer Kangaroo” of South Pittsburg, Tennessee, even made it all the way to the pages of New York’s daily newspapers.

During mid-January of 1934, a huge nasty kangaroo spread terror among the Tennessee hill farmers. This extremely atypical kangaroo was reported to have killed and partially devoured several German police dogs, geese, and ducks.

The Reverend W. J. Hancock saw the animal and described it as fast as lightning, and looking like a giant kangaroo as it ran and leapt across a field. Another witness, Frank Cobb quickly came upon more evidence of the kangaroo’s activities. The head and shoulders of a large German shepherd or Alsatian were all that remained. A search party tracked the kangaroo to a mountainside cave, where the prints disappeared.

In recent years, local rival newspaper writers have tried to blame this Tennessee Killer Kangaroo story on the pen of the late Horace N. Minnis, a South Pittsburg correspondent of the Chattanooga Times. The only trouble with this “newspaper hoax” theory is that Minnis was not a newspaper correspondent for the area in 1934.
