Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

The Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Features and favorable exploration direction of normal faults in Jurassic strata in northern central Sichuan Basin, China

Journal of Natural Gas Geoscience, 2023
Studies focusing on the fault system in the Jurassic strata of the Sichuan Basin have been limited, restricting the understanding of the hydrocarbon accumulation mode of the Shaximiao Formation and the expansion of exploration. Through interpretation and

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

The Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

An overview of the postcranial osteology of caecilians (Gymnophiona, Lissamphibia)

The Anatomical Record, EarlyView.
Abstract Caecilians comprise a relatively small (~220 species) group (Gymnophiona) of snake‐like or worm‐like, mostly tropical amphibians. Most adult caecilians are fossorial, although some species may live in aquatic or semi‐aquatic environments, either as larvae or adults.

JURASSIC PALEONTOLOGICAL HERITAGE OF MURCIA (BETIC CORDILLERA, SOUTH-EASTERN SPAIN)

Rivista Italiana di Paleontologia e Stratigrafia, 2004
Jurassic rocks of the External and Internal Zones of the Betic Cordillera are widespread in the province of Murcia. Four areas are considered of special interest for stratigraphical and paleontological analysis: a) Sierra Quípar and b) Sierras Lúgar ...

Pangean (Late Carboniferous–Middle Jurassic) paleoenvironment and lithofacies

Palaeogeography, Palaeoclimatology, Palaeoecology, 2000
Abstract Six time interval maps were constructed that depict the plate tectonic configuration, paleogeography and lithofacies for Pangea from the Late Carboniferous through the Middle Jurassic. Generally, the individual maps illustrate the conditions present during the maximum marine transgressions of higher frequency cyclicity within the Absaroka ...

Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications

The Anatomical Record, EarlyView.
Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Inside a duck‐billed dinosaur: Vertebral bone microstructure of Huallasaurus (Hadrosauridae), Upper Cretaceous of Patagonia

The Anatomical Record, EarlyView.
Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent
