Phylogeny of Titanosauria #1

I am currently working on coding any and all titanosaurs into the matrix of Gonzalez et al (2016), describing Notocolossus. Just as a preliminary test, I have added a few new taxa, including Argyrosaurus, Hypselosaurus, Quetecsaurus and Puertasaurus. The results is shown below, although narrowed down to only show Titanosaurs.

T – Titanosauria A – Argyrosauridae L – Lognkosauria P – Puertasaurinae M – Lithostrotia S – Saltasauridae O – Opisthocoelicaudiinae

The main things of interest if that Argyrosauridae is resolved, and places sister to Lognkosauria, and Hypselosaurus placed as a Saltasaurid, in a polytomy with Saltasaurus, Alamosaurus, Trigonosaurus, Nemegtosaurus, Opisthocoelicaudiinae, and what would normally be Nemegtosauridae, but currently excludes the name genus.

About ijreid

I am an amateur palaeontologist thats hobbies include studying extinct amniotes, specifically dinosaurs, birds, and mammals. Occasionally, I focus my time on detailed and accurate illustrations of dinosaurs, and I have completed drawings of Dysalotosaurus, Micropachycephalosaurus, Zhuchengtyrannus, Troodon, Eotyrannus, Europelta, and Achillobator. I do not believe in copyrights, and think that the world would be better if everything was open access.
