Anatomy of the maxillary canal of Riograndia guaibensis (Cynodontia, Probainognathia)—A prozostrodont from the Late Triassic of southern Brazil

open access: yesThe Anatomical Record, Volume 308, Issue 3, Page 827-843, March 2025.
Abstract Investigating the evolutionary trajectory of synapsid sensory and cephalic systems is pivotal for understanding the emergence and diversification of mammals. Recent studies using CT‐scanning to analyze the rostral foramina and maxillary canals morphology in fossilized specimens of probainognathian cynodonts have contributed to clarifying the ...

Late Cambrian Syn‐Intrusive Thickening of the Ikh Mongol Arc Domains in the Mongolian Collage

open access: yesTectonics, Volume 44, Issue 1, January 2025.
Abstract Structural analysis, U–Pb monazite and xenotime dating, Ar–Ar dating of biotite and amphibole and thermodynamic modeling of peak metamorphic assemblages allow constraining the tectono‐thermal evolution of the migmatite‐magmatite domain on the southern periphery of Precambrian Zavkhan Block. The main subvertical metamorphic fabric resulted from

Tidal versus fluvial point bars: Key features from the integration of outcrop, core and wireline log information of Triassic examples

open access: yesThe Depositional Record, Volume 10, Issue 5, Page 793-820, November 2024.
Abstract The Triassic red beds of the Tabular Cover of the Iberian Meseta are an excellent reservoir outcrop analogue, a direct consequence of high‐quality exposures, which offer exceptional three‐dimensional outcrops, as well as a wide variability of depositional environments.
