EDIT 20100324: Redo and expansion.
This is what held my nose to the grindstone for the best part of the last two weeks. If there ever was something that tested my resolve* it was this: on the first version you could tell there was point were I simply gave up on a coherent style. Now my resolve to "finish" this was such that I welcomed the 7 km trek** to the local retail park to fetch a new pair of headphones for the time off the grindstone and the luxury of having music while on it.
Remembering how I sat dazed on my bed not quite able to lie down and sleep after working without that amenity, I'm pretty sure the hits of the last three decades of the 20th century helped me to hold on to what sanity I have. While musical tastes offer little to dispute, I may still have had some lingering effects as I redid this not only once, fixing the aforementioned stylistic issues of the first version, but twice, expanding the phylogenetic detail boosted by the overall success of the first try and dissatisfied with the subsequent editing.
Don't get me started on the minor epic of trying to convert this from *.ai to *.pdf: what you find here is the best I can do though pointers on how to do it better (i.e., make the *.pdf behave like an *.ai while zooming) are very welcome.

Is this finished? Not by a long shot. Even as I write this I'm already planning to redo the phyletic certainty markers, to find a font that allows wider formatting options, to update this as my hard drive references allow and to figure out what to do with the white spaces around the tree. Loftier aims include graphically codifying clade definition types and expanding this tree at least to Amniota.

(Un)fortunately, while this was fun as a test to myself, I'd rather apply myself to studying Immunology now if you don't mind. That said, I would rather be made aware of any editing mishaps as quickly as possible.

Old Artist's Comments
Just yesterday I realized I could submit this here *rolls eyes* I finished the work and did the half-assed preview for the *.pdf download.
Beware that although this is based in a relatively recent source, 2 years old, time is usually unforgiving to such conceptual constructions. I've cleared away from tentatively placed clades so you won't find
Compsognathus or Columbiformes here but this should however give you a good idea of how dinosaurs are related with each other.

*Or I may have a very, very stubborn streak. Take it as you will.
**I think I walked a total of 16 km in that journey. Good thing I was prescient enough to take my camera with me.

Done in Illustrator 10.

Not sure that I love the formatting -- there's a lot of unnecessary wiggling on the y-axis that doesn't seem to convey any kind of information, but which is, nevertheless, very distracting.

But I'm grumpy, old fashioned, work on crurotarsans and inherently distrust supertrees, so feel free to ignore me.

Yes, I can see that the wiggling can be distracting, but it's a necessary evil to avoid branches from colliding too often* and to keep the tree moderately compact :shrug:

No problem. I'll see if I can do anything about the wiggling as I'm redesigning the branches. I can't promise much tough. Just sayin'.

*The main threat to my sanity by far.

Looks really great!

I know: a chart just shy of a meter square is very sizable indeed.


Seriously now, thank you for the compliment and for the challenge :)

Muito interessante, embora o facto do Nyctosaurus estar na base do groupo em vez de estar ao mesmo nível que o Pteranodon e o Ornithosthoma seja pouco provável, caso contrário a diversificação dos pterossauros ornithocheiróides seria muito maior no final do Cretáceo...algo que me agrada, mas tendo em conta o quão semelhantes esses pterossauros são é pouco provável que o Nyctosaurus fosse outra coisa senão um pteranodontídeo

Isso tem muito que ver com a referência que usei já ter 6 anos :P Francamente desconhecia (ou não lembrava) a situação actual até a ter verificado aqui, [link] .

I'm having trouble downloading it...

It's working fine on my side :confused:
As it could be some sort of server mishap I'd give it some time. You could also try it with another browser.

If all else fails I can e-mail this to you :)

Good lord.

That is way more work than I'd ever have the patience to attempt.

Actually it was just a question of preparing templates for the forks and copy/paste them all over the file, minimizing the arising conflicts. I however did spend most of the evenings of one week doing this and still I left Charadriomorphae unresolved... Until I fixed it yesterday.
