An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

open access: yesThe Anatomical Record, EarlyView.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Cortical bone distribution in the human mandibular symphysis: Ontogenic and morphometric approaches in archeological context

open access: yesThe Anatomical Record, EarlyView.
Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...

Over the edge: Empirical evidence for the cliff‐edge model of obstetric selection

open access: yesThe Anatomical Record, EarlyView.
Abstract The cliff‐edge model of obstetric selection maintains that larger neonates and smaller birth canals confer a positive selective advantage until labor becomes obstructed and vaginal delivery is no longer possible, eliciting an abrupt reduction in fitness.

Widespread distribution of large silesaurids evidenced by a new record from the Middle Triassic of southwest Gondwana

open access: yesThe Anatomical Record, EarlyView.
The largest silesaurid known from South America is described here, demonstrating that silesaurids reached large body sizes in southwestern Gondwana. This discovery further underscores the widespread geographic distribution and temporal persistence of large silesaurids across Pangea, despite faunal turnovers and environmental events such as the Carnian ...

Detrital zircons from Lower Triassic sandstones, Belsky depression, Pre-Uralian foredeep: LA-ICP-MS U-Pb isotopic ages and distribution of rare and trace elements

open access: yesЛитосфера, 2016
Lower Triassic sandstones in the southern part of Belsky depression (Pre-Uralian foredeep) contain detrital zircons with concordant U-Pb isotopic ages ranging from Neoarchean to the boundary of the Carboniferous and Permian.

Zooarchaeological Analysis of an Atoll Assemblage From Central Micronesia

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT There has been a dearth of archaeological research on atolls in the central‐eastern Caroline Islands of Micronesia. This has limited our understanding of pre‐contact subsistence and settlement strategies in these more marginal and remote environments, particularly in regards to zooarchaeological data.
