A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin)

open access: yesThe Anatomical Record, EarlyView.
Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...

Habitat Preferences at the Leading Edge of a Marine Bioinvasion

open access: yesEcology and Evolution
ABSTRACT To enable the early detection and eradication of invasive species, it is crucial to predict habitats with an elevated risk of invasion. Despite the fact that invaders may display initial habitat preferences and niche shifts during range expansion, studies identifying habitat associations at invasion ...

Habitat preference by lizards and habitat cover in the survey area at Dragonera Islet.

open access: yes, 2012
Habitat preference by lizards (bars in black) was based on the proportion of visual censuses (n = 506 lizards) whereas habitat cover (bars in red) was calculated from a habitat map which only covers the area of visual censuses.

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

open access: yesThe 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
