E. M. Kindle — Section at Cape Thompson, Alaska. 523 



in these beach outcrops and the accessible or northern portions 

 of the Cape cliffs are indicated by the following section : 



Section IJf at Cape Thompson. 



cl Light buff or cream-colored limestone with numer- 

 ous fossils. Str. about N. S., dip variable, 

 mostly E. 25 to 90', complicated toward the 

 south 500' -f 



c Black and buff thin-bedded limestone, the former 

 predominating. Productus and large crinoid 

 stems abundant 380' 



b Bluish gray to black fissile shale with abundant 



plant fragments. Dip E. 80 to 90°. Str. N. 15 W. 280' 



a Very thin-bedded lead gray sandstone with occa- 

 sional bands of brown ferruginous chert and 

 films of coal. Plant fragments abundant. Str. 

 N. 15° W. Dip E. 86 to 90°. 140' 



The lower 400 feet of the section appears to contain no 

 invertebrate fossils. All or nearly all of these beds represent 

 non-marine sediments. Plant remains in various stages of 

 maceration occur through most of the shales and sandstones 

 below the limestone. Plant fossils were obtained from both a 

 and b of the section and numbered respectively lots 5289 and 

 5290. These were submitted to Dr. David White, whose 

 report follows : 



"Lot 5289. This lot consists of three fragments of coarse, gray 

 sandstone bearing carbonized impressions of pieces of par- 

 tially decorticated stems. The characters of the very 

 imperfect impressions point toward a close affinity with 

 Tepidodendron corrugatum. 



Lot 5290. This lot includes two small packages of wavy, black 

 carbonaceous shale splitting in thin laminae. This shale 

 contains many fragments of leaves of Tepidodendron, 

 and unidentifiable, decorticated stem fragments of several 

 kinds, together with several imperfect remains in a better 

 state of preservation. The latter represent Sphenopteris 

 frigida Heer, twigs of Lepidodendron ~Veltheimianum as 

 generally identified in the European and Arctic "floras, 

 with a cone fragment possibly belonging to the same spe- 

 cies, and portions of a Lepidophyllum very close to Lepi- 

 dophyllum fuisseense Vaff. There are also present several 

 fragments of a cyclopterid type ; these are so incomplete 

 that it is not really possible to decide whether they repre- 

 sent (a) rachial pinnules of Neuropteris; (b) some large, 

 broad pinnuled Aneimit.es ; or, (c) pinnules of Cardiopteris. 

 I am inclined to refer them to the latter genus. 

 The plant remains from Cape Thompson are so fragmentary 



and meager as to determinable species as not to permit a close
