We got this press release about the new San Marco Dirty seat. For a company that size to make a BMX saddle that should mean something. No pivotal though but steel/carbon rails and a sintex cover. It weighs in at 325 grams and they're asking almost 40 Euros for it (€ 39,95). The dimensions are: 235 mm x 134 mm. 
After doing a BMX 'zine for ten years (1987 - 1996) FATBMX made it on the internet. The year was 1998. Here to stay.
