Modularity and heterochrony in the evolution of the ceratopsian dinosaur frill
Ecology and Evolution, 2020 The fossil record provides compelling examples of heterochrony at macroevolutionary scales such as the peramorphic giant antlers of the Irish elk.

Pararhabdodon Isonensis and Tsintaosaurus Spinorhinus: A New Clade of Lambeosaurine Hadrosaurids from Eurasia [PDF]
, 2009 We present new anatomical information showing that Koutalisaurus kohlerorum, from the Maastrichtian of Lleida Province, northeastern Spain, is most probably the junior synonym of Pararhabdodon isonensis from the same region.

The Anatomical Record, EarlyView.Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

Temporal and phylogenetic evolution of the sauropod dinosaur body plan [PDF]
, 2016 The colossal size and body plan of sauropod dinosaurs are unparalleled in terrestrial vertebrates. However, to date, there have been only limited attempts to examine temporal and phylogenetic patterns in the sauropod bauplan.

The Anatomical Record, EarlyView.Abstract Hadrosaurid dinosaurs are generally regarded as “crested” or “non‐crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non‐crested” hadrosaur is known to have possessed a soft tissue cranial crest (or comb), based on an exceptionally preserved “mummified” specimen. Here we redescribe this specimen and

Comment on “A new Arctic hadrosaurid from the Prince Creek Formation (lower Maastrichtian) of northern Alaska” by Hirotsugu Mori, Patrick S. Druckenmiller, and Gregory M. Erickson [PDF]
Acta Palaeontologica Polonica, 2016 Recently Mori et al. (2016) published a paper describing a new tax- on of hadrosaurid dinosaur from the Upper Cretaceous Prince Creek Formation of the North Slope Alaska, a rock unit that has recently proven to be a productive source of scientific ...
