"NASA Announces Site of 'Great Dying' Meteor Crater

[]
Researchers funded by NASA and the National Science Foundation have located 
the site of an impact crater. The crater is believed to be associated with 
the largest extinction event in Earth's history about 250 million years ago. "

Concerns the Bedout structure offshore in the Canning Basin, NW Australia. 
Gravity measurements seem to indicate that the size of the structure is 
comparable to Chicxulub and cores contain what certainly seems to be impact 
melt/breccias at 3,000 m depth.

Unfortunately nothing on how the crater was dated, at least  not in the 
material NASA has put online.
