According to Weekly World News reporter Mike Foster, "leading geneticist" Ian McCaulway says a two-ton spherical object found in the Australian outback is actually a memento of some enormous extraterrestrial's digestive tract.

Foster said DNA testing performed on the sphere had produced inconclusive results, although the inclusion of some kangaroo and cow material in the sphere indicated that the object's creator had fed on those creatures shortly before extruding the sphere.

The sphere had originally been found by UFO buff Pat Tambrush a few days after a large UFO was sighted over the Great Sandy Desert of northwestern Australia. Upon ascertaining that the object was not in fact a spacecraft, Tambrush rolled it back to display in front of his bar.

"It's possible this hairball comes from a domesticated animal of extraterrestrial origin," he told the News. "Human explorers since the days of Christopher Columbus have brought pets such as cats along on their journeys."

Although Foster said the sphere was now under study at "a research center near Sydney," no additional details were forthcoming to independently confirm the story. Likewise, no record of McCaulway or his undoubtedly distinguished genetic career was immediately available.
