Radio carbon dating has since been carried out on the remains, revealing the individual conclusively died before 1950.
Police said the results indicated it is most probable the person died sometime between 1800 and 1899.
The age and sex of the individual are yet to be determined.
Police are now referring a report to the coroner.
Brisbane historian Jack Sim previously told ABC News that the remains were unlikely to be from a home burial because even in Brisbane’s early days Teneriffe was considered an inner city suburb and formal graves were available.
