An archaeological dig has begun in Queensland, but it is a different kind to the sort usually seen in the fossil-heavy state.

The University of Southern Queensland (USQ) has begun excavations at Toowoomba’s Royal Bulls Head Inn.

The dig will investigate the rich history lying beneath the surface at the site, which dates to 1847 and known as one of the oldest extant historic buildings in the region.

“What is probably less well known is that originally the inn itself was surrounded by a suite of ancillary buildings,” USQ’s Professor Bryce Barker said.

“This included a secondary cottage, a butchers shop, stables as well as an earlier version of the hotel which was replaced by the present structure.”

A geophysical has been undertaken to develop a better understanding of spatial aspects of the site, estimate levels of preservation across the property and help identify suitable locations for digging.

Professor Barker said the excavations will include archaeology students and documentary film makers from USQ, volunteers from the public and over 80 students from nearby high schools.

“A field laboratory will be set up to allow preliminary sorting and identification of material retrieved during excavation and further geophysical work will be carried out over the week,” he said

“Thus all facets of archaeological field work will be able to be experienced by volunteers.

The site will be open to the public over the weekend of October 18, as part of the Toowoomba Open House event.
