It’s time to crack open the champagne and hit the town because Tet Zoo ver 3 just hit the ‘200 article’ mark: specifically, Because caecilians are important was # 200.

That caecilians piece was a republished section of a longer article originally published on Tet Zoo ver 2: as I think I already said, some time soon I need to revisit caecilians and extensively update what I have. On the matter of lissamphibians, salamanders need revisiting too since I also want to extensively revise the old articles from ver 2. Anurans (frogs and toads) still haven’t been given extensive coverage on Tet Zoo. So much diversity and so much work on fossil and extant lineages that neither I nor anybody else has really reviewed properly online. Projects of mine that involve ichthyosaurs, Mesozoic dinosaurs, birds, and the ever-present azhdarchid pterosaurs will also be covered soon enough. Oh yeah, and then there’s all the stuff on non-mammalian synapsids, Paleogene mammals and temnospondyls that’s sitting there in my files, awaiting completion. If only I could put more time into blogging. I can’t, the constant quest for cash always takes precedence.

Other things I’d really like to publish here if only time allowed: body language in archosaurs and how you can make your images of fossil crocodylomorphs and dinosaurs all that more interesting, my overdue reviews of von Grouw’s The Unfeathered Bird and Loxton and Prothero’s Abominable Science!, the Dougal Dixon interview on speculative zoology (yes, it just happened), the rest of the toxodont series, and the Piltdown Man article I’ve been tinkering with since 2006.

So… 200 articles. I don’t have anything particularly interesting to say about this fact. I did think about counting up the articles and seeing which groups have won the most coverage and so on, but that’s the sort of thing I save for the birthday articles. A quick look reveals the same sort of pattern I’ve come to expect: mammals and birds are tremendously well represented and non-avialan dinosaurs are fairly healthily represented while non-mammalian synapsids fail to get a look-in and anamniotes (‘amphibians’) are not covered in sufficient depth. At least croc-group archosaurs are fairly well covered, with much more to appear as time allows.

Anyway, all we’re seeing here is a list of the articles that have appeared on ver 3 so far. Actually, while I know that I’ve published 200 ver 3 articles, I seem to have missed one or two in the list here – I’m not sure how. If you know which articles those are, let me know and I’ll add them. Anyway, producing this list is a good idea since it’s not always easy to find old articles (the SciAm blog site is not, in my opinion, especially easy to search or navigate). And arranging articles in a subject-arranged format, as here, always seems wise.

I’ve interspersed the list with assorted images for your amusement.

All that remains for me to say is: thanks to everyone who reads, comments, and provides advice, commentary, support and assistance.
