The oldest platypus and its bearing on divergence timing of the platypus and echidna clades
TLDR
Evidence from high-resolution x-ray computed tomography indicating that Teinolophos, an Early Cretaceous fossil from Australia's Flat Rocks locality, lies within the crown clade Monotremata, as a basal platypus is described, suggesting that rate heterogeneities may have affected mammalian evolution in such a way as to defeat strict molecular clock models and to challenge even relaxed molecular Clock models when applied to mammalian history at a deep temporal scale.
Chubutemys, a New Eucryptodiran Turtle from the Early Cretaceous of Argentina, and the Relationships of the Meiolaniidae
TLDR
Chubutemys copelloi is the oldest nonmarine cryptodire from South America represented by a skull and an enclosed canalis caroticus internus extending to the posterior margin of the pterygoid, showing that it is a eucryptodire.
Theropod Fauna from Southern Australia Indicates High Polar Diversity and Climate-Driven Dinosaur Provinciality
TLDR
Most dinosaur groups probably attained a near-cosmopolitan distribution in the Jurassic, prior to fragmentation of the Pangaean supercontinent, and some aspects of the hallmark ‘Gondwanan’ fauna of South America and Africa may therefore reflect climate-driven provinciality, not vicariant evolution driven by continental fragmentation.
Polar dinosaur bone histology
ABSTRACT We report on the bone microstructure of a hypsilophodont and an ornithomimosaur from the Early Cretaceous, Otway Group of Dinosaur Cove in south-eastern Australia, which at the time lay well
