This had already been prepublished online a few months ago. Now we learn (at 
last) that Nature's online pre-publications are not considered to have the 
official publication date.

Interesting how it uses "reptile" as something like "squamate" or 
"lepidosaur" or maybe even "toxicoferan", as in "[t]hese molecules [the 
large array of toxins] represent a tremendous hitherto unexplored resource 
not only for understanding reptile evolution but also for use in drug design 
and development" or "the complex and bioactive secretions present in 
'non-venomous' lizards forces a fundamental rethinking of the very concept 
of 'non-venomous' reptile".
