The dental plate on bichir pectoral fins: A unique dermal skeletal element bearing individual odontodes with tooth‐like replacement

Journal of Anatomy, EarlyView.
Pectoral fins of bichirs encompass the so‐called dental plates – unique dermal skeletal elements with individual odontodes identical to the oral teeth. Abstract The dermal skeleton appeared early in vertebrate evolution in the form of mineralized skin denticles composed of tooth‐like units—odontodes.

Determining impact angle from the spatial distribution of shock metamorphism: A case study of the Gosses Bluff (Tnorala) impact structure, Australia

Meteoritics &Planetary Science, EarlyView.
Abstract The majority of planetary impacts occur at oblique angles. Impact structures on Earth are commonly eroded or buried, rendering the identification of the direction and angle of impact—using methods such as asymmetries in ejecta distribution, surface topographic expression, central uplift structure, and geophysical anomalies—challenging. In this

Fascinating single‐cell red algae: models for evolution and adaptation

New Phytologist, EarlyView.
Summary The unicellular red algae, Cyanidiophyceae, that diverged early during Archaeplastida (algal and plant) evolution, occupy a variety of extreme habitats that are inhospitable for most other eukaryotes. With the use of modern genomics and genetics methods, Cyanidiophyceae show a remarkable taxonomic diversity, share haplodiplophasic life cycles ...

Contractional kink bands formed by stress deflection along pre-existing anisotropies? Examples from the Anglo-Brabant Deformation Belt (Belgium) and the North Dobrogea Orogen (Romania) [PDF]

, 2008
Kink bands within two slate belts, the Anglo-Brabant Deformation Belt (Belgium) and the North Dobrogea Orogen (Romania), reveal similar problems with respect to linking kink band geometries to expected palaeostress directions.

Crustal structure beneath the Trondelag Platform and adjacent areas of the Mid-Norwegian margin, as derived from wide-angle seismic and potential field data [PDF]

, 2010
The outer mid-Norwegian margin is characterized by strong breakup magmatism and has been extensively surveyed. The crustal structure of the inner continental shelf, however, is less studied, and its relation to the onshore geology, Caledonian structuring,
