US man's fossil find stumps experts
Dayton - Experts in the US are trying to figure out what a 450 million-year-old fossil dubbed "Godzillus" used to be.
The 68kg fossil recovered last year in Kentucky is more than 2m long. The Dayton Daily News reports scientists at a Geological Society of America meeting viewed it Tuesday in Ohio.
University of Cincinnati geologist Carl Brett told The Cincinnati Enquirer that it's the largest fossil ever extracted from that era in the region, once covered by water.
Amateur palaeontologist Ron Fine spotted the fossil on a hillside last year.
