Cretaceous
The oldest known [cough… African… cough] ant
Here’s a perfect example of what I like about blogs becoming an integral communication tool for the scientific community and interested folks alike:

- A peer-review paper gets published;
- The media gets hold on the story;
- The blogs react: scientists and general public fill the comments section (in the genuine tone of the internets);
- The authors of the original paper join in the discussion.
Discussion may get heated, comments may get bitter, but the results are always rewarding for all.
