Amount vs Isotope edit

Uhh, isn't the most important suggestion of the "extraterrestrialness" of the Iridium layer not that it contains 100X more Iridium than "normal"; but rather, that it contains a significantly different distribution of isotopes [than terrestrial]? That's certainly what I was taught at school, albeit that was >50 years ago LOL. 124.183.93.28 (talk) 11:09, 14 September 2012 (UTC)Reply
