New dinosaurs include ornithopod Trinisaura santamartaensis, oviraptorosaur Yulong mini, deinonychosaur Eosinopteryx brevipenna, and bird Sulcavis geeorum. Scolosaurus cutleri is resurrected as a valid taxon.

Oviraptorosaurs are shown to have had very muscular tails, probably for use in visual display. Studies on the osteology of Khaan mckennai, convergence between the tails of dromaeosaurids and rhamphorhynchid pterosaurs, an injured sauropodomorph tail, hunting methods of Pygoscelis adeliae, neuroanatomy of Ampelosaurus, the benefits of pheomelanin in birds, genomic diversity in Columba livia, and new specimens of Archaeorhynchus spathula are published. Confuciusornis sanctus specimens without retrices are confirmed to be female. Parts of the long-lost Titanosaurus indicus holotype have been rediscovered. Detailed analysis is done on theropod teeth from the Late Cretaceous of North America, allowing for potential differentiation between different taxa.

And we have a fourth described Antarctic dino. I can't wait until we have descriptions for the various others, such as the hadrosaurs and dromaeosaurs known from the continent.

Hopefully they can diagnose Titanosaurus!

I'm assuming Scolosaurus didn't have those spikes on its tail it's traditionally been portrayed with?

Indeed it didn't.

Good ol' Scolosaurus :D
I'm very glad they finally solved the Confuciusornis case!
