Abstract Actinopterygii is a major extant vertebrate group, but limited data are available for its earliest members. Here we investigate the morphology of Devonian actinopterygians, focusing on the lower jaw. We use X‐ray computed tomography (XCT) to provide comprehensive descriptions of the mandibles of 19 species, which span the whole of the Devonian

Identification of potential groundwater sources using Electrical Resistivity Imaging (ERI) method in Jambu Lawar, Machang, Kelantan [PDF]
The study area is primarily composed of volcanic rock and plain quaternary sediment. Extrusive and intrusive rocks are the two varieties of igneous rock that have been found. In the examined location, igneous intrusive rock, specifically biotite granite,

Genesis of Soils Formed from Mafic Igneous Rock in the Atlantic Forest Environment
Different parent materials participate in the formation of soils in the hilly landscape of “Mar de Morros” in the Atlantic Forest environment. Those derived from mafic igneous rock (gabbro) frequently show erosion problems because of land use, which is ...

Abstract Dicynodonts (Anomodontia: Dicynodontia) were one of the main groups of terrestrial tetrapods in Permian and Triassic faunas. In Brazil, the genus Dinodontosaurus is one of the most common tetrapod taxon in the Triassic Santa Maria Supersequence. This genus has a complex taxonomic history and is represented in the Triassic of both Argentina and
