298 The Upper Cretaceous Floras of the World 



The Priesener beds, first described by Beuss in 1 844 as the " Planer 



Mergel," transgress the Teplitzer beds. They comprise strictly marine 



fossiliferous marls with an abundant fauna, including 1 Iguanodon ( ?), 



29 Pisces, 25 Cephalopoda, 55 Gastropoda, 79 Pelecypoda, 3 Brachiopoda, 



3 Bryozoa, 32 Crustacea, 6 Vermes, 11 Echinodermata, 8 Anthozoa, 7 



Porifera, 90 Foraminifera, and 11 Eadiolaria. The greater part of the 



Priesener beds are referred to the Upper Turonian, although their upper 



portion is believed to extend into the Emscherian. The flora, while not 



extensive, is of considerable interest. It includes the following species: 



Anthocephale bohemica Bayer 

 Araucaria brachyphylla Bayer 

 Araucaria frici Velenovsky 

 Ardisia glossa Bayer 

 Ceratostrobus echinatus Velenovsky 

 Chondrites furcillatus Rcemer 

 Diospyros primwva Heer 

 Ficus cecropial-lobus Bayer 

 Frenelopsis bohemica Velenovsky 

 Ilex perneri Bayer 

 Myrsine caloneura Bayer 

 Myrsine manifesto. Bayer 

 Quercus charpenteri Heer 1 

 Rhus dens mortis Bayer 

 Rubwphyllum gaylussacite Bayer 

 Sequoia lepidota Bayer 

 Sequoia reichenbachi (Geinitz) Heer 

 Widdringtonia parvivalvis Bayer 



Of these 18 species 13 are peculiar to this horizon, 4 come up from the 

 Perucer, or other Cenomanian beds, and 1 is common to the Teplitzer 

 beds. 



Emscheeian. — The Senonian is represented in the Bohemian area by 

 only the Emscherian or lower Senonian. The beds are generally known 

 as the Chlomeker Schichten, although some authors segregate the lower 

 Chlomeker under the name of the Kreibitzer Schichten. The extensive 

 marine fauna includes 1 Mososaurus (?), 5 Pisces, 17 Cephalopoda, 60 

 Gastropoda, 84 Pelecypoda, 2 Brachiopoda, 1 Bryozoa, 4 Crustacea, 2 



1 A fragment not identical with Heer's Tertiary species and not certainly a 

 Quercus.
