A description of dental microanatomy and implantation geometry in Chamaeleonidae

Journal of Anatomy, EarlyView.
A reassessment of the dental histology in adult chamaeleons reveals the presence of periodontal ligament. Alongside alveolar bone and cementum, these tissues together constitute a compacted and remodelled tripartite periodontium. Our findings include the novel observation of plicidentine‐like protuberances of dentine within underlying bone.

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman

Journal of Petroleum Geology, EarlyView.
ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.

Arc polarity reversal in North Luzon preserved in the Oligocene–Miocene clastic units in southwestern Mountain Province, Philippines: insights from trace element geochemistry, microfossil ages, and zircon U–Pb dating

Geoscience Letters
Provenance studies using sedimentary geochemistry, particularly whole-rock, trace element, and rare earth element (REE) analyses, have proven useful in complex terranes such as the Philippines.

Evolution, Routing and Reservoir Characteristics of Submarine Channels in a Structurally Deforming Slope Setting: Deep‐Water Joint Development Zone of Nigeria and São Tomé and Príncipe

Journal of Petroleum Geology, EarlyView.
ABSTRACT Deep‐water slope channels and associated facies are a major part of clastic sediment dispersal system extending from the shelf‐edge to the abyssal plain. The toe‐thrust area of the deep‐water Niger Delta enables the analysis of these channels and their interaction with evolving fault‐controlled sea‐floor topography to be determined ...

1D Basin Modelling of Upper Jurassic to Upper Cretaceous Source Rocks in the Southern Pletmos Sub‐Basin, Outeniqua Basin, Offshore South Africa

Journal of Petroleum Geology, EarlyView.
ABSTRACT The Pletmos sub‐basin in the Outeniqua Basin, offshore South Africa, is divided by the Superior, Pletmos and Plettenberg faults into northern and southern depocentres. In this study, geological and organic geochemical data together with 1D basin modelling were used to investigate the burial, thermal and maturation histories, and the timing of ...

Complete organellar genomes of Cystophora brownii: Insights into mitochondrial and plastid structure and evolution in brown algae

Journal of Phycology, EarlyView.
Abstract Cystophora (order Fucales) is one of the most diverse genera of habitat‐forming brown algae and is endemic to temperate reefs of Australia and New Zealand. Species in this genus form complex habitat structures that support diverse marine communities and contribute to coastal productivity. However, Cystophora spp.

Phylogenomics of the American robin (Turdus migratorius) reveals hidden lineages and introgression

Journal of Systematics and Evolution, EarlyView.
Phylogenomic analyses of Turdus migratorius uncover four previously unrecognized lineages, including a divergent Baja California lineage (T. m. confinis). The results reveal complex evolutionary relationships that depart from simple models of continuous divergence, supported by evidence of introgression between the Mexican lineage and its previously ...
