An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

open access: yesThe Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Deep-water turbidite systems: a review of their elements, sedimentary processes and depositional models. Their characteristics on the Iberian margins - Sistemas turbidíticos de aguas profundas: revisión de sus elementos, procesos sedimentarios y modelos deposicionales. Sus características en los márgenes Ibéricos [PDF]

open access: yes, 2015
Turbidite systems or submarine fans are considered the most important clastic accumulations in the deep sea and represent the sediment-transfer system between the hinterland source area and the deep-sea depositional sink.

Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988

open access: yesThe Anatomical Record, EarlyView.
Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

Cranial anatomy of a Late Cretaceous aspidorhynchid fish (Neopterygii: Aspidorhynchiformes) from Alberta, Canada

open access: yesThe Anatomical Record, EarlyView.
Abstract Belonostomus longirostrisis was named for an isolated jaw fragment from freshwater Upper Cretaceous (Campanian) sediments of the Dinosaur Park Formation of Alberta, Canada. Following the description of the Albertan species, numerous isolated cranial and postcranial elements have been collected from the Dinosaur Park Formation and assigned to B.

Evolution of the Giant Foresets Formation, northern Taranaki Basin, New Zealand [PDF]

open access: yes, 2002
Plio-Pleistocene aggradation and progradation has resulted in the rapid outbuilding of the continental shelf margin, northern Taranaki Basin. Seismic reflection profiles reveal that this outbuilding is characterised by bold clinoforms which offlap in a ...

The internal crest anatomy of Lambeosaurini (Hadrosauridae: Lambeosaurinae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The supracranial crests of lambeosaurine hadrosaurids have long been a focus of study due primarily to their extreme morphology. The external anatomy of lambeosaurine crests is understood to be highly variable between species, but variation in their internal anatomy is less well understood.

Integrating transitional-flow signatures into hybrid event beds: implications for hybrid-flow evolution on a submarine lobe fringe

open access: yesJournal of Sedimentary Research
ABSTRACT Alongside turbidites and debrites, hybrid event beds are now recognized as a common occurrence in deep-marine environments. Yet, many variations in the standard H1–H5 facies model of Haughton et al. (2009, Marine and Petroleum Geology, v. 26, p.

State of the Art in Swath Bathymetry Survey Systems [PDF]

open access: yes, 1988
In the last decade, advances in real-time computing and data storage capabilities have led to significant improvements in bathymetric survey systems and the single point echo-sounder has now been replaced by a variety of highresolution swath mapping ...

Cannabinoids and drug–drug pharmacokinetic interactions: Deciphering the risks

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
The relationship between cannabinoids and mental health has become a major focus of scientific inquiry and public discourse. Cannabinoids are diverse chemical compounds from the Cannabis species that have been explored for their therapeutic applications in treating chronic pain, psychiatric and neurological conditions, such as depression, schizophrenia,

Sentience in cephalopod molluscs: an updated assessment

open access: yesBiological Reviews, EarlyView.
ABSTRACT This article evaluates the evidence for sentience – the capacity to have feelings – in cephalopod molluscs: octopus, cuttlefish, squid, and nautilus. Our framework includes eight criteria, covering both whether the animal's nervous system could support sentience and whether their behaviour indicates sentience.
