Revisiting a long‐overlooked skull: Implications for the distribution of Dinodontosaurus brevirostris (Kannemeyeriiformes) in the Brazilian Triassic

The Anatomical Record, EarlyView.
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

Light echoes reveal an unexpectedly cool Eta Carinae during its 19th-century Great Eruption

, 2011
Eta Carinae (Eta Car) is one of the most massive binary stars in the Milky Way. It became the second-brightest star in the sky during its mid-19th century "Great Eruption," but then faded from view (with only naked-eye estimates of brightness).

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

The Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

SOLAR ERUPTION ON 4 JANUARY 2011: CASE STUDY FOR SPACE EARLY WARNING [PDF]

, 2011
We perform intuitive analysis for solar eruption on 4 January 2011. Since we do not have magnetic observational data from the eruption, we perform first order calculation and expands it as interplanetary total effect of energy propagation by retro ...

Evolution of V838 Monocerotis during and after the 2002 eruption

, 2005
By fitting the available photometric data on V838 Mon with standard supergiant spectra we have derived principal stellar parameters, i.e. effective temperature, radius and luminosity, and followed the evolution of the object since its discovery in early ...

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs

The Anatomical Record, EarlyView.
Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

The Anatomical Record, EarlyView.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

Eruptive syringomas

Dermatology Online Journal, 2005
Eruptive syringoma is a rare clinical presentation of a benign tumor of the eccrine ducts. It consists in successive crops of small skin-colored papules on the anterior body surfaces. It generally occurs in the peri-pubertal period. Treatment of this benign condition is cosmetic only.

Supernumerary teeth in the premaxillary region: its effects on the eruption and occlusion of the permanent incisors

Australasian Orthodontic Journal, 1990
The presence of supernumerary teeth in the premaxillary region may cause a variety of pathological effects. This study was carried out to determine the various aspects of supernumerary teeth in the premaxillary region, particularly the effects of the ...
