Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

The Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

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

The 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

The 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 ...

Exploring the cranial morphology and possible convergences of Triassic non‐crocodylomorph pseudosuchians (Archosauria: Pseudosuchia) with other sauropsids through linear morphometrics

The Anatomical Record, EarlyView.
Abstract Triassic pseudosuchians had highly diversified cranial morphologies. These archosaurs occupied diverse ecological roles, ranging from terrestrial predators and herbivores to semiaquatic ambush predators and possible waders. Here, we apply linear cranial morphometrics to assess possible convergences with other sauropsids from the clades ...

Description of large, well‐preserved Enchodus specimens from the Bearpaw Formation of Alberta, Canada

The Anatomical Record, EarlyView.
Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.
