Nothing here really adds up. 1. The earliest pyramids in mesoamerica currently known are about half the age claimed in the BBC article. There are older pyramids in South America (specifically Brazil), but still nothing as old as is claimed here. 2. The linked page says this complex may have been submerged after the last ice-age, but that would actually double the age of the site! 3. The depth of the site (reported on the BBC link) is 650 meters below current sea level, but only 183 meters on the wordpress link. However, at peak glaciation during the last ice age, sea levels were only about 130 meters lower than they are today. If we don't use the BBC article's numbers (could be a metric-imperial conversion error) that still leaves over 50 meters difference, which is rather a lot of subsidence given the geology of the region! 4. The BBC article is over a decade old, but no new findings have been reported in that time. Whether it's 650 or 183 meters deep, somebody would have sent a sub down for a better look by now if it actually existed. Shenanigans! My guess is that this is the blogspam driven resurrection of an old hoax.
