Middle Ladinian Ammonoids Of The Hallstatt Limestone In Austria

Dear Fossil Forum members! This report deals with ammonoids from the former zone of Protrachyceras archelaus, which is our present Longobardian within the Ladinian stage of the marine Triassic timescale. Fig.1 A beautiful view of the surging “rock waves” of the incoming tectonic thrust sheets. The valley between the two Mountains in the middle of the picture marks the tectonic border between the mainly Triassic Hallstatt Unit and the Tirolikum Unit of the Totengebirgs nappe (in the backgrou

The Tuvalian Substage Of The Triassic Hallstatt Limestone In Austria

The Tuvalian Substage Of The Triassic Hallstatt Limestone In Austria Written by Andreas Spatzenegger Dear Fossil Forum members! This report will introduce you to the Tuvalian substage (uppermost Carnian/ Triassic) of the so called Hallstatt limestone in Austria. View above the Hallein-Berchtesgaden Triassic area to the Watzmann and the Hochkalter mountains. The name of this substage was chosen by "Old master" Mojsisovics from the mediaeval name of the hill ridge/salt mine area between the

The Zones Of Austrotrachyceras Austriacum And Trachyceras Aonoides

The Zones of Austrotrachyceras austriacum and Trachyceras aonoides, Triassic/Karnium/Julium of the Alps Written by Andreas Spatzenegger Dear Fossil Forum members! This report will introduce you to the ammonite-zones of Trachyceras aonoides and Trachyceras austriacum within the Hallstatt limestone in Austria. Both zones are ammonoid zones of the Julian, which is the lower stage of the Carnian. These two zones are comparable with the North American Desatoyense (in most parts), Obesum and Nans

Ammonites From The Zone Of Cyrtopleurites Bicrenatus

Ammonites from the Zone of Cyrtopleurites bicrenatus, Nor/Alaunium1 of the Hallstatt limestone Written by Andreas Spatzenegger Fig. 0 The „Hohe Dachstein" mountain with fresh fallen snow in spring; The Dachstein is the highest mountain in the Salzkammergut area and the so called Dachstein limestone is named after this mountain. Below the glacier, the partly forest covered mountain is named „Hirlatz". This is the type locality of the liassic „Hirlatz limestone". Down below the Hirlatz

The Columbianus Zone/alaunium 2/ Norium/upper Triassic, In The So Called “Hallstatt Limestone” Of The Northern Calcareous Alps In Austria

The columbianus Zone/Alaunium 2/ Norium/Upper Triassic in the so called "Hallstatt Limestone" of the Northern Calcareous Alps in Austria Dear Fossil Forum members! This pictured report about the ammonite bearing Triassic Hallstatt limestone will be the first one of a continuous series of reports. Since the beginning of the geological research in the Northern Calcareous Alps of Austria in the 19th century, about 500 species of Triassic ammonites have been described from the Hallstatt limestone

My Triassic Blog

Dear Visitors of my blog! Welcome to this blog. I hope you enjoy it and have a good time staying here. About me and my collecting area: I am a fossil collector living in Austria. My favourite fossil collecting field are the ammonoids of the middle to upper Triassic "Hallstatt" limestone in the Northerrn Calcerous Alps. Hallstatt limestone represent a type of condensed triassic "ammonitico rosso" facies which do also occur in several other parts of the world. Greece, Hungary, Romania, Bosnia
