It doesn't say which dating methods were used here, only that the date was determined by extracting blood-- and I'm not sure how one would date something based on organic materials. Unless the spider was radioactive of course. (In that case, the movie ends up really bad for the humans)
Peter Parker did well with a radioactive spider, didn't go so well for Gwen Stacy, however...
(darn, I'm old...)

The article failed to mention the "Born on date" found in the spider's wallet.
The organic materials would contain C-14 (radioactive carbon, which decays at a set rate and, mildly more controversely, is believed to exist at a set baseline % of total carbon at a given time).
Assuming one does not eat after death, the shortfall of the baseline % tells you how old something organic was when it stopped eating (e.g., died).
