Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications. [PDF]

open access: yesAnat Rec (Hoboken)
Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Small body size and extreme cortical bone remodeling indicate phyletic dwarfism inMagyarosaurus dacus(Sauropoda: Titanosauria) [PDF]

open access: yesProceedings of the National Academy of Sciences, 2010
Sauropods were the largest terrestrial tetrapods (>105kg) in Earth's history and grew at rates that rival those of extant mammals.Magyarosaurus dacus, a titanosaurian sauropod from the Upper Cretaceous (Maastrichtian) of Romania, is known exclusively from small individuals (<103kg) and conflicts with the idea that all sauropods were massive.
