Migaloo, world’s first bioarchaeology detection dog

Monday, September 3rd, 2012

Migaloo and Gary JacksonGary Jackson, owner of Multinational K9 Dog Training in Brisbane, Australia, has been training dogs in everything from basic obedience to highly specialized detection for government and corporations for decades. Now he can add another specialty to his roster of pioneering cane toad, koala and quoll detection dogs: Migaloo, the world’s first dog trained to detect archaeological human remains.

250-year-old Aboriginal bone on a rod so it can be inserted through tube into ventilating chamberUnlike cadaver dogs, which use their advanced olfactory senses to detect the scent of decomposing human flesh, Migaloo detects bones hundreds of years old, and not just an entire skeleton but even tiny fragments of bone no larger than a tooth. Jackson spent six months training the Labrador mix using 250-year-old Aboriginal bones (handled with the utmost respect according to Aboriginal traditions) on loan from the South Australian Museum. The bones were placed in protective tubes with a ventilation chamber attached that allows the scent to filter through. The human remains were then buried in an impromptu graveyard/proving ground at depths ranging from one to three feet. Numerous animal bones — including kangaroo, horse, chicken, cat — were scattered around as decoys. Migaloo quickly became adept at detecting and indicating only the human bones from as far away as 20 feet, detecting even the traces of bones that had been present 24 hours earlier and then removed.

Migaloo indicating a tree burialWearing her stylish new custom-made jacket with an Australian Aboriginal Flag design, Migaloo successfully conducted her first operational find at an undisclosed location in the Queensland outback in May of this year. After searching miles of terrain and hundreds of trees for traces of historical burials, she indicated strongly on one Eucalyptus tree. The team surveyed the hollow tree non-invasively and indeed found archaeological human remains, buried inside the tree according to an ancient Aboriginal funerary practice. The bones were not disturbed by request of the traditional owners of the land.

On an Aboriginal burial ground on Yorke Peninsula in South Australia, Migaloo found four burial spots, one of them 600 years old and 8 feet underground. It has never been excavated and was known only because a post-hole digger found a bone fragment deep under the surface which was radiocarbon dated to 600 years ago. That’s a world record, as far as we know.

Candy and Bill indicating human remains from War of 1812, 1987The oldest human remains detected by canine before now were 175 years old. In December of 1987, Candy, a chocolate Lab cadaver dog handled by legendary law enforcement dog trainer Bill Tolhurst, indicated human remains on a spot in Fort Erie, Ontario, Canada. The archaeologists didn’t have funding to excavate the spot at that time, but once the money came through they excavated the place Candy had pointed to and found three skeletons of men killed during the Battle of Snake Hill during the War of 1812. That record has stood until now.

Migaloo’s abilities are an exciting development for archaeologists in Australia and around the world. Candy wasn’t trained to specifically pick up archaeological remains. Her regular job was working with the police to find cadavers. If Migaloo can be trained to find human skeletal remains that are hundreds, maybe thousands of years old, she and other dogs like her will be a powerful new tool for archaeologists.

Red Centre Consultancy director Bud Streten, who owns Migaloo, plans to use her as a non-invasive way of locating and protecting traditional burial sites.

“It is a massive breakthrough, not only here in Australia but we’ve got some interest from overseas for use in other ancient civilisations.

“At the moment in the world of archaeology there is no tool that can tell you there are human remains underground, we use ground penetrating radar, magnetic susceptibility and historical or oral records.

“But now Migaloo the wonder dog can do it.”

See Migaloo perform her record-breaking feat of findery in the following YouTube video. Protip: you’ll want to turn the volume way up when Quenten Agius of the Adjahdura Land Traditional Owners Group speaks because his voice is much more quiet than anyone else’s.
