Allgau Formation

The Allgau Formation is a geologic formation in Austria. It preserves fossils dating back to the Jurassic period. Initially and formally defined by Jacobshagen. Allgau Formation formerly known as spotted marls and spotted marly limestones represented by dark-grey bioturbated limestones and marlstone interbeds. It represents basinal hemipelagic facies common in Alpine Tethys regions of Alps, Carpathians and other mountain ranges. Several horizons of the formation are particularly rich on ammonite fauna.


Arimao Formation


Artemisa Formation

The Artemisa Formation is a geologic formation in western Cuba. It preserves mainly ammonite fossils dating back to the Late Oxfordian to Tithonian period. The formation is divided into two members; La Zarza and Sumidero Members. Most of the formation was deposited in deeper marine conditions.


Aurora Limestone


Becraft Formation

The Becraft Formation is a geologic formation of marine sedimentary rock found in New York State. The Becraft is a part of the lower Devonian Helderberg Group and conformably overlies the New Scotland Formation and is overlain by the Alsen Formation throughout the lower Hudson Valley of New York State. The formation is Gedinnian in age. Outcrops of the formation are found from the New York-New Jersey border to the Helderbergs of Albany County, New York and as far west as Schoharie County, New York. The thickness of the formation varies from around 3 meters in Canajoharie to 8 meters thick ...


Blue Lias

The Blue Lias is a geologic formation in southern, eastern and western England and parts of South Wales, part of the Lias Group. The Blue Lias consists of a sequence of limestone and shale layers, laid down in latest Triassic and early Jurassic times, between 195 and 200 million years ago. The Blue Lias is famous for its fossils, especially ammonites. Its age corresponds to the Rhaetian to lower Sinemurian stages of the geologic timescale, thus fully including the Hettangian stage. It is the lowest of the three divisions of the Lower Jurassic period and, as such, is also given the name Low ...
