An international team of scientists has described a fossil marine predator measuring 8.6 meters in length (about 28 feet) recovered from the Nevada desert in 2010 as representing the first top predator in marine food chains feeding on prey similar to its own size. A paper with their description will appear the week of January 7, 2013 in the EE (early electronic) issue of Proceedings of the National Academy of Sciences.
