Massospondylus carinatus is a basal sauropodomorph dinosaur from the early Jurassic Elliot Formation of South Africa. It is one of the best-represented fossil dinosaur taxa, known from hundreds of specimens including at least 13 complete or nearly complete skulls. Surprisingly, the internal cranial anatomy of M. carinatus has never been described using computed tomography (CT) methods. Using CT...

Stem and leaf anatomy of Origanum rotundifolium Boiss., O. vulgare L. ssp. viride (Boiss.) Hayek, Teucrium hircanum L., belonging to Lamiaceae were characterized and compared. Some important differences were determined in the taxa. In addition, trichome diversity was investigated by light microscopy and three main types of trichomes (peltate, capitate glandular and non-glandular) were observed ...

Salvia indica L., which belongs to section Aethiopis, is a perennial herb usually growing on rocky limestone slopes and Quercus scrubs in the Southeast Anatolia. In this study, the morphological, anatomical and palynological characteristics of this species using Scanning Electron Microscopy (SEM) have been investigated. In addition, nutlet morphology, emended and expanded description, phenology...

Capsicum species are frequently described in terms of genetic divergence, considering morphological, agronomic, and molecular databases. However, descriptions of genetic differences based on anatomical characters are rare. We examined the anatomy and the micromorphology of vegetative and reproductive organs of several Capsicum species. Four Capsicum accessions representing the species C. annuum...

A redescription of conchological and anatomical characters of the planorbidae mollusc Plesiophysa ornata (Haas, 1938) is presented, based on topotypic material and specimens from 14 additional localities in the Brazilian states of Rio Grande do Norte, Paraíba, Sergipe, Bahia, Espírito Santo and Minas Gerais. Due to the close similarity of their shells, a sure discrimination of the five species ...

Asymmetrical feathers have been associated with flight capability but are also found in species that do not fly, and their appearance was a major event in feather evolution. Among non-avialan theropods, they are only known in microraptorine dromaeosaurids. Here we report a new troodontid, Jianianhualong tengi gen. et sp. nov., from the Lower Cretaceous Jehol Group of China, that has anatomical ...

Vessels and tracheids represent the most important xylem cells with respect to long distance water transport in plants. Wood anatomical studies frequently provide several quantitative details of these cells, such as vessel diameter, vessel density, vessel element length, and tracheid length, while important information on the three dimensional structure of the hydraulic network is not considere...

The genus Astrantia L. is a perennial plant which belongs to the Umbelliferae family and is represented by only A. maxima Pallas which has two subspecies (subsp. maxima and subsp. haradjianii (Grintz.) Rech. fil.) in Turkey. Subsp. haradjianii is endemic and very common. In this study, Astrantia specimens were collected from different localities and investigated for morphological and anatomical...

The artiodactyl astragalus has been modified to exhibit two trochleae, creating a double pullied structure allowing for significant dorso-plantar motion, and limited mediolateral motion. The astragalus structure is partly influenced by environmental substrates, and correspondingly, morphometric studies can yield paleohabitat information. The present study establishes terminology and describes d...

conclusions this study did not show that distal radius anatomical indices including the radial height, radial inclination, ulnar variance and volar tilt influence perilunate fracture dislocation as risk factors. background distal radius radiographic indices may play a role as risk factors in pathogenesis of kienbock’s disease, scaphoid fracture and non:union:. perilunate fracture dislocations a...
