The anatomy of Dolichocebus gaimanensis, a stem platyrrhine monkey from Argentina.
Diffusible iodine‐based contrast‐enhanced computed tomography (diceCT): an emerging tool for rapid, high‐resolution, 3‐D imaging of metazoan soft tissues
A critical review of the recent contributions to iodine‐based, contrast‐enhanced CT research is provided to enable researchers just beginning to employ contrast enhancement to make sense of this complex new landscape of methodologies.
CALSOYASUCHUS VALLICEPS, A NEW CROCODYLIFORM FROM THE EARLY JURASSIC KAYENTA FORMATION OF ARIZONA
Abstract We describe a new fossil crocodyliform archosaur from the Early Jurassic Kayenta Formation of the Navajo Nation that is surprisingly derived for so ancient a specimen. High-resolution X-ray…
Iconography : 3D computational imaging of the petrosal of a new multituberculate mammal from the Late Cretaceous of China and its paleobiologic inferences
The facial skeleton of the early Oligocene colodon (perissodactyla, tapiroidea)

Two skulls of the early Oligocene Colodon from the White River Group in South Dakota are much more derived than previously reported. In particular, morphologies of the facial skeleton and narial…
Nonhuman anthropoid primate femoral neck trabecular architecture and its relationship to locomotor mode
Strong trabecular architecture similarity across body sizes, anthropoid phylogenetic backgrounds, and locomotor mode might be explained by greater similarity in anthropoid hip joint loading mechanics than previously considered.
Technical note: CT thresholding protocols for taking measurements on three-dimensional models.
This study sought to investigate the effects of taking linear measurements on three-dimensional models using a modified version of the HMH protocol and examined the accuracy of the thresholding protocol, measurements were taken from high resolution X-ray computed tomography data and compared with measurements taken on dried specimens.
A new fossil species supports an early origin for toothed whale echolocation
It is inferred that a rudimentary form of echolocation evolved in the early Oligocene, shortly after odontocetes diverged from the ancestors of filter-feeding whales (mysticetes), which in turn led to marked, convergent changes in skull shape in the relatives of Cotylocara, and in the lineage leading to extant odontOCetes.
Tapiroidea and other moropomorphs
Forelimb-hindlimb developmental timing changes across tetrapod phylogeny
Major heterochronic changes in early limb development and chondrogenesis were absent within major clades except Lissamphibia, and their presence across vertebrate phylogeny are not easily correlated with adaptive phenomena related to morphological differences in the adult fore- and hindlimbs.
