The first recovery of the conodont Hindeodus parvus from Žiri (Slovenia) a few years ago highlights this area for Early Triassic biostratigraphical study. Systematic sampling of five sections in the ...Idrija–Žiri area has yielded the new species Platyvillosus corniger sp. nov. and Neospathodus planus sp. nov. Based on these new species and other conodont elements collected here, nine discrete conodont Unitary Association (UA) zones are proposed for this area. In ascending order they are: Eurygnathodus costatus Zone (UA 1), Eurygnathodus hamadai Zone (UA 2), Foliella gardenae Zone (UA 3), Neospathodus robustus Zone (UA 4), Platyvillosus corniger Zone (UA 5), Platyvillosus regularis Zone (UA 6), Triassospathodus hungaricus Zone (UA 7), Triassospathodus symmetricus Zone (UA 8), and Neospathodus robustispinus Zone (UA 9). The conodont and δ13C data indicate that these conodonts span the Dienerian/Smithian (i.e. Induan/Olenekian) boundary interval to the Spathian, and they also indicate that Triassospathodus hungaricus Zone (UA 7) does not occur at the base of the Spathian. These conodont zones are valuable for stratigraphic correlation within Central and southern Europe, and they also promote a better correlation worldwide. Conodonts in the Idrija–Žiri area were adapted to a shallow-water environment in an epeiric ramp.
•Nine discrete conodont zones are identified for the Early Triassic in Idrija–Žiri, Slovenia.•δ13C data and conodonts indicate that these sections span the late Dienerian to Spathian.•According to δ13C data the Smithian/Spathian boundary is characterized by Foliella gardenae.•These conodonts were adapted to a shallow-water environment in an epeiric ramp.•This unique conodont sequence was probably the result of paleoecological influence and/or provincialism.

En este artículo se ...realiza un análisis tanto de la historia (abordando aspectos como el Estado, el poder, la fiscalidad, la sociedad...) como de la cultura material del reino zirí granadino (reconstruyendo el posible trazado urbano de este periodo y sus diferentes elementos).
Detailed conodont biostratigraphy and lithostratigraphy of the Late Permian and Early Triassic beds were studied at the LukaC section in western Slovenia. The analyzed section is composed of the ...Bellerophon Formation ("evaporite-dolomite member") and the newly introduced Lukaè Formation ("transitional beds", "streaky limestone member" and "carbonate-clastic beds member"). The Permian-Triassic boundary interval is represented by "transitional beds" of carbonate facies deposited in shallow restricted marine conditions. The presence of H. parvus in sample L1 in the "transitional beds" marks the systemic boundary between Permian and Triassic. The studied interval is characterized by a diverse microfauna that contain conodonts, foraminifers, ostracods and gastropods. Six conodont zones have been recognized, in ascending order, the latest Changhsingian (uppermost Permian) praeparvus Zone, and the Griesbachian (lowermost Triassic) parvus, lobata, staeschei-isarcica, postparvus and anceps zones. This faunal succession represents the first known and the most complete conodont biozonation across the Permian-Triassic interval from the entire Dinaric region. The recognized conodont biozones can be correlated with the biozonation of the Southern Alps and of the GSSP Meishan D section.
Foraminifers from the Upper Permian Bellerophon Formation, Permian-Triassic "transitional beds" and lowermost Triassic "streaky limestone member" of the Lukač Formation in the Lukač section, western ...Slovenia are described and illustrated. Four new species of foraminifers are described: Multidiscus zhiriensis, M. dinaridicus and Globivalvulina lukachiensis from the Upper Permian, and Lingulonodosaria slovenica from the lowermost Triassic. The assemblage of Late Permian foraminifers consists of species characteristic of the Changhsingian of many regions in the Tethys: northwestern Caucasus, Transcaucasia, Iran, Turkey, northern Italy, northwestern Serbia, northeastern Hungary, and South China. Unfortunately, the uppermost part of the Bellerophon Formation in the Lukač section is represented by dolomite and does not contain foraminifers. The Permian-Triassic boundary interval is represented by carbonate "transitional beds" deposited in a shallow restricted marine environment that contains foraminifers and conodonts. The species "Cornuspira" mahajeri, "Earlandia" gracilis, and "E" tintinniformis, marking the lower boundary of the Triassic worldwide based on foraminifers, are found both below and above the first appearance of the conodont species Hindeodus parvus in the Lukač section. These species appear to be ecological species and their appearance coincides with a stressful shallow water environment. The first interval with nodosariid foraminifers appears 2m above the P/T boundary and a second one is approximately 5m above the boundary. Both of these intervals with nodosariids are within the range of the conodont species H. parvus and within the I. staeschei–I. isarcica conodont Range Zone.
This study documents the Permian–Triassic Boundary in the Žiri area of western Slovenia. A paleontological study of the Lukač section, northwest of Žiri, resulted in the recovery of a variety of ...microfossils. This report documents the conodont fauna recovered from the section. This is the first report of the
Hindeodus–
Isarcicella population in Slovenia and it provides important new biostratigraphic data for the definition of the Permian–Triassic Boundary.
Hindeodus parvus has been recovered, and its first appearance in the lowermost Werfen Formation indicates the base of the Triassic Period. Based on the conodont taxa

A, at least three faunas can be distinguished, and they make possible a worldwide correlation.
Tras una rápida revisión de los escasos datos conocidos sobre la vida y la obra de Ibn Abī l-Riŷāl (fl. Túnez c. 996-1048), se analiza el contenido de su Urŷūza fī aḥkām al-nuŷūm comparándola con su ...célebre al-Kitāb al- Barī‘ fī aḥkām al-nuŷūm concluyéndose que se trata de dos obras independientes y que la Urŷūza no es un resumen del Barī‘. El trabajo continúa con datos biobibliográficos del historiador, matemático y astrólogo Ibn Qunfuḏ al-Qusanṭīnī (1339-1407), autor de un comentario a la Urŷūza de Ibn Abī l-Riŷāl dedicado a Abū Bakr b. Abī Muŷāhid Gazī Ibn al-Kās, visir de los sultanes meriníes Abū Fāris (1366-1372) y Abū Zayyān (1372-1374). La obra parece haber sido redactada durante el breve reinado de este último y antes de la deportación del dedicatario a Mallorca en 1375. Se analiza el contenido del comentario, las fuentes citadas en el mismo, las técnicas astrológicas utilizadas tanto por Ibn Qunfuuḏ como por Ibn Abī l-Riŷāl y el uso, por parte del comentarista de un zīŷ derivado del de Ibn Isḥāq. El artículo termina con un comentario detallado de los horóscopos contenidos en la obra de los que uno corresponde al equinoccio vernal del año 571 de JC, en el que se produjo una conjunción de Saturno y Júpiter que anunció el advenimiento del Islam, mientras que los once restantes constituyen una historia astrológica del Marruecos meriní entre 1348 y 1366. Dos de ellos habían sido publicados en un artículo anterior. En lo que respecta a los nueve restantes, en seis de ellos se identifica el sujeto o acontecimiento al que aluden, quedando tres por identificar.
The paper deals with the stratigraphy of Late Permian and Early Triassic strata of the Lukač section in the Žiri area of western Slovenia. This is the only section presently known in the External ...Dinarides where the Permian-Triassic boundary is defined following international criteria based on the first appearance of the conodont Hindeodus parvus. The following lithostratigraphic units have been formalized: the Bellerophon Limestone and Evaporite-dolomite Members of the Bellerophon Formation and the Luka~ Formation with the three members,the Transitional Beds, Streaky Limestone and Carbonate-clastic Member. The paper presents the results of micropaleontologicalstudy based on foraminifers and conodonts as well as petrographic and sedimentologic research results. The investigation of conodont assemblages enabled the conodont biozonation of the Permian-Triassic interval of the studied Lukač section.
