After three years of monthly (and sometimes more frequent) entries, I've finally finished what I set out to do: provide a short description of every titanosaur. That was enough time for eleven new genera and species to be described, and one species covered in the second post to be moved to a new genus (Aeolosaurus maximus to Arrudatitan). To make it easier to navigate the whole shebang, I've created a new page, "Your Friends The Titanosaurs", that collects them all. I've also flipped branches on The Compact Thescelosaurus: macronarians now come after diplodocoids, instead of the other way around.
After all that work, I feel I've earned the right to wave my arms through one last post, to summarize some general considerations that didn't have a place in the other posts.
