 I've got a question about theropod height, and another about Dromaeosaurids... 

Well, 2 years ago, you gave me a hand with a school project I was working in by making this size chart.

Well, I managed to get the highest possible mark in that subject, so that compensated for some weaker marks, and I managed to enter University without much pressure, so thanks again. Anyway, I was recently surfing the web and I came across this image: http://kronosaurus82.deviantart.com/art/Biggest-Ugliest-Baddest-140881861 As you can see, the animals that appear in it are the same as in the size chart you made, however, we can see some discrepances in their height. So, my question is, is this reconstruction correct in this regard? Tyrannosaurids having longer leg bones that Allosauroids and Spinosaurids (and the latter having a lower profile that other theropods) is pretty common knowledge, and longer leg bones mean more height, but, still, the mounted skeleton of Sue is not that much taller that mounted Giganotosaurus, if I recall correctly, and the mount of Spinosaurus is quite massive...

Anyway, about Dromaeosaurs, do you have any idea about the environment Deinonychus and Utahraptor lived in? I ask, mainly, because of the whole feather density (or oven presence, in some cases, it seems), and, after seeing how you reconstructed Achillobator, and the reasoning behind the ratite feathering you gave it, I've been pondering how that could affect medium-large dromaeosaurs in less arid climates.

In any case, could I ask you a favour, if you have the time and the inmediate means? If yes, remember the giant bird size chart?  
Could you add a Velociraptor mongoliensis silouette to it, if you can? I mainly need it to driving a point straight home (not like it is that needed, the paper that describes the quill knobs on that genus is pretty good evidence for wings, but, still...). Again, if you have time. In any case, Deinonychus' height would be slighty higher if it adopted a more natural position that the crouching (or as so I see it, correct me if needed) one it is displaying in the chart. Also, do you think Aepyornis would be heavier that Utahraptor? Seeing that the model for estimating weights was deemed somewhat flawed, and that, at least in the chart, Aepyornis has a larger body, well, yeah...

By the way, I like how you classified Oviraptorosaurs as an order of Aves, and Deinonychosaurs as part of Archaeopterygiformes. It, well, makes sense, that classification should get more standariced. One tends to forget about those things when thinking in a cladistic way, but, that update would be something needed to change the overall image of those animals. I may start writting them in that way, well, when I get my licenciature and start doing actual work and research in place of preparing exams. Well, better that ""when"", ""if"", but I hope I do.

Anyway, keep up your good work, I've been following your blog, and I like what I read over there!
