Impact of Dietary Patterns on Migraine Management: Mechanisms of Action and Recent Literature Insights. [PDF]

Brain Behav
ABSTRACT Purpose Migraine headaches are a common and debilitating neurological disorder that significantly impacts the quality of life of affected individuals. Dietary patterns have been increasingly recognized as potential factors in the prevention and management of migraines. This comprehensive review aims to provide a comparative analysis of various

A new tiny fossil penguin from the Late Oligocene of New Zealand and the morphofunctional transition of the penguin wing. [PDF]

J R Soc N Z
ABSTRACT The Late Oligocene is a period of high penguin diversity, following major changes in the marine environment at the Eocene/Oligocene boundary and prior to the emergence of crown penguins in the Miocene. Historically, a large morphological gap existed between the most crownward Platydyptes among the Oligocene penguins from New Zealand and the ...

Osteohistology of the Maastrichtian, small-bodied elasmosaurid Kawanectes lafquenianum (Sauropterygia; Plesiosauria). [PDF]

J Anat
The present contribution brings new osteohistological information on the postcranial bones of Kawanectes lafquenianum and shed some light on Plesiosauria microanatomy and microstructure. The bone architecture shows variability between forelimbs and hindlimbs.

Analyzing the Life History of Caimans: The Growth Dynamics of Caiman latirostris From an Osteohistological Approach. [PDF]

J Morphol
This research offers insights into the life history and growth dynamics of Caiman latirostris, highlighting their growth patterns, aging, and attainment of sexual maturity, and how environmental conditions impact their development. This study has direct implications for understanding the life histories of extinct archosaurs and other sauropsids ...

Body size and evolutionary rate analyses reveal complex evolutionary history of Alvarezsauria. [PDF]

Cladistics
Abstract Some of the smallest examples of dinosaurian body size are from alvarezsaurians, an enigmatic group of maniraptoran coelurosaurians with a peculiar combination of anatomical features unique among theropods. Despite the large number of alvarezsaurian species described worldwide and the increased understanding this has provided, the body‐size ...

The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

The Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

Histology and fossil diagenesis of a pterosaur tooth from the Crato Formation (Lower Cretaceous of Brazil)

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).

Dental crown morphological variation and heterodonty in carcharhiniform sharks

The Anatomical Record, EarlyView.
Abstract Elasmobranch teeth are highly mineralized structures that constitute the majority of the fossil record for this group. Despite their taxonomic and evolutionary significance, detailed descriptions of dental morphology remain scarce. The order Carcharhiniformes, the most diverse among sharks, comprises 304 valid species that display remarkable ...
