In the present paper, we describe several coleoid jaws discovered in lower Toarcian black shales, cropping out along Vilyui River (Yakutia, Russia). This is first record of a Lower Jurassic jaw outside Europe and report such finding from Mesozoic Siberia. The described demonstrate same mode preservation morphology as coeval previously reported Europe. Their Siberia became possible due to widesp...

jurassic deposits are well exposed in the bazehowz area, south west of mashhad city, east alborz, iran. it contains plant macrofossilsbelonging to eighteen species of eleven genera of various orders such as equisetales, filicales, bennettitales, cycadales,corystospermales, caytoniales, ginkgoales and pinales. two biozones were recognized in the type section of bazehowz formation.biozone i is an...

The unique climate conditions of Plateau State and the numerous tourism attraction and spots has made Plateau State the home of peace and tourism and also tourist haven of Nigeria. This paper is centered on five resorts in Plateau State such as National Museum, Jos Wildlife Park, ASSOP Falls, Pandom Wildlife Park and Solomon Lar Amusement Park. Data for resort patronage were provided only in Na...

There are a number of fundamental problems in assessing the astronomically forced cyclostratigraphy of the Jurassic Period. First, Jurassic geochronology is not well constrained, due to a general scarcity of radiometric dates, inferior precision of the existing ones, and large inaccuracies in stratigraphic constraints. These problems are particularly troublesome in the Early to Middle Jurassic ...

Docodonts are aMesozoicmammal group (Synapsida:Mammaliaformes) with a fossil record from theMiddle Jurassic to the late Early Cretaceous. With highly distinctive molars for both shearing and grinding functions, docodonts are inferred to have diverse dietary adaptations, including insectivory, omnivory, and even carnivory. This group also offers the earliest-known case of mammalian swimming adap...

The first Upper Jurassic fossil of the family Ommatidae (Coleoptera: Archostemata) from Australia is described and illustrated from a single specimen discovered at the Talbragar Fish Bed. Rhopalomma stefaniae gen. et sp. n. is classified in Ommatidae based on the length and insertion of the antennae, the tuberculate cuticle, the pattern of elytral striae, the complete epipleura and the presence...

Large-offset oceanic detachment faults are a characteristic of slow- and ultraslow-spreading ridges, leading to the formation of oceanic core complexes (OCCs) that expose upper mantle and lower crustal rocks on the seafloor. The lithospheric extension accommodated by these structures is now recognized as a fundamentally distinct "detachment-mode" of seafloor spreading compared to classical magm...
