Petroleum geology of the Upper Jurassic – Lower Cretaceous of East and North-East Greenland: Blokelv-1 borehole, Jameson Land Basin: Biostratigraphy of the Hareelv Formation (Upper Jurassic) in the Blokelv-1 core, Jameson Land, central East Greenland [PDF]
Geological Survey of Denmark and Greenland Bulletin, 2018 The Hareelv Formation in the Blokelv-1 core is biostratigraphically subdivided by means of ammonite and dinoflagellate cyst stratigraphy. The succession ranges from the Oxfordian C. densiplicatum Chronozone to the Volgian P. elegans Chronozone.

Jurassic ammonites of the Wulong area, Tingri County, Tibet
, 2015 The Jurassic succession west of Wulong village, Tingri County, southern Tibet, is described. Lithostratigraphical classification uses pre-existing terminology for formations, and an informal subdivision into members is proposed.

Evolution in Upper Jurassic Ammonites [PDF]
Evolution, 1959 Evolution in ammonites has been known for nearly a century. It was mainly under the influence of Charles Darwin (1859) that paleontologists began to look for successions of similar species and to connect these species into lineages. These early studies of evolution in ammonites are due to, e.g., Waagen (1869), Neumayr (1873) and Gemmellaro (1872-82 ...

The Jurassic of North-East Greenland: Jurassic dinoflagellate cyst stratigraphy of Hold with Hope, North-East Greenland [PDF]
Geological Survey of Denmark and Greenland Bulletin, 2004 Dinoflagellate cysts of the Middle–Upper Jurassic succession on northern Hold with Hope have been studied in order to establish a biostratigraphic framework and to date the succession.
