HOUSTON (AP) The discovery of a second ancient burial site in the path of a new road under construction in Harris County is prompting calls for an area scientific study before the project moves forward.

University of Houston anthropologist Kenneth Brown told a Harris County judge Monday that the human remains could be as old as 9,000 years.

The Houston Chronicle (http://bit.ly/QIy5wE ) reports Brown testified on behalf of the Harris County Historical Commission, which is challenging the Texas Department of Transportation's request to remove the bones and any others in the way of the $322 million project.

Judge Reece Rondon says he'll rule on the request this week.

Construction was stopped in the area last week. The Grand Parkway, a four-lane toll road, will be part of a beltway around greater Houston.
