Enigmatic Fossils from the Lower Carboniferous Shrimp Bed, Granton, Scotland
The Lower Carboniferous (Visean) Granton Lagerstätte (Edinburgh, Scotland) is principally known for the discovery of the conodont animal, but has also yielded numerous crustaceans and other faunas. Here we report on small branching colonies, reaching 10 mm in length. They are small, erect, arborescent, and irregularly branched with predominant monopodial and dichotomous growth. They bud in a si...
متن کاملNew Ediacara fossils preserved in marine limestone and their ecological implications
Ediacara fossils are central to our understanding of animal evolution on the eve of the Cambrian explosion, because some of them likely represent stem-group marine animals. However, some of the iconic Ediacara fossils have also been interpreted as terrestrial lichens or microbial colonies. Our ability to test these hypotheses is limited by a taphonomic bias that most Ediacara fossils are preser...
متن کاملDrowning of algal mounds: records from the Upper Carboniferous Lower Pseudoschwagerina Limestone, Carnic Alps, Austria
Anthracoporella algal mounds, up to 22 m thick, occur within the cyclic sequences of the Lower Pseudoschwagerina Limestone (uppermost Carboniferous), Carnic Alps (Austria). Their depositional environment lay between the wave base and the base of the photic zone. The algal mounds are overlain by dark, well-bedded, cherty wackestones and packstones. The cherty limestones contain cephalopods, thic...
متن کاملCorrection: Enigmatic Fossils from the Lower Carboniferous Shrimp Bed, Granton, Scotland
The following text, which appears as the second paragraph of the Introduction, should not be included in the Introduction, but instead in the Fig 1 legend: “LWM and HWM refer to Low Water Mark and High Water Mark respectively. Based upon British Geological Survey geological map. 1:50000 Series. Edinburgh Scotland Sheet 32 E [7], with the permission of the British Geological Survey.” Please see ...
متن کاملInvestigation of some factors that affect jakura limestone burning
Limestone calcination reaction seems to be a very simple and straight-forward reaction. However, there are numerous critical variables that exert profound effect on lime burning operations. The factors and variables that affect the burning of limestones must be considered in the selection, design and optimization of the calcininig equipment. Limestone burning in a vertical kiln often presents c...
