A week later, I finally got the chance to sit down and score
Nanningosaurus into Evans and Reisz's dataset. The results were 3
MPTs, TL 121, CI 0.835, RI 0.878
3 MPTs, 121 steps, CI- 0.834, RI 0.878
Topology does not vary from that of the original authors (Evans and
Reisz), except for the presence of Nanningosaurus between Aralosaurus
and Tsintaosaurus. This does not conflict with the topology found by
Mo et al. given that they had scored Nanningosaurus into Horner et
al.'s dataset which I suspect was completed and submitted to the
reviewers for the Dinosauria II long before most of the recent
publications came out on Amurosaurus, Aralosaurus, Charonosaurus,
Olorotitan and so on. I'm being tolerably nice this evening and
cutting them some slack based on their dataset choice. Obviously, it'd
have been nice if they'd included it in something a little more
inclusive, such as Prieto-Marquez's work (which is a little bit better
than Horner et al.'s in some aspects), or a composite effort from
several different sources, or at the very least, scored in those
additional lambeosaurines. Horner et al.'s dataset is fairly
expansive, but seems to suffer from a bad case of "Amero-centrism",
largely ignoring a great deal of non-NAm taxa (I do believe what I
suggested earlier is the cause of this though).
As I get more time, I'll keep poking into this, I suppose.
Only 20.2% of the total characters were able to be scored-
