36 KENTUCKY GEOLOGICAL SURVEY. 



The principal exposures seen on the east side of the anticline 

 were in the Maysvilie section, about five miles south of Mays- 

 ville; on the east side of the Licking river in Fleming county, 

 near Wyoming; and in a number of railroad cuts west of Rich- 

 mond and for several miles east; on the west side of the anti- 

 cline near Mt. Washington in Bullitt county; north of High 

 Grove in Spencer county; in Nelson county; on the Bardstown 

 pike near Cox's creek; and in Washington county about five 

 miles Avest of Springfield. 



Richmond Group. 



With the close of the Mavsvilie, the period of uniformity over 

 wide areas in the interior region during Cincinnatian times, 

 ceases. The Richmond shows very much more difference geo- 

 graphically than the Winchester, Eden, or Mavsvilie. The 

 faunas are more limited horizontally, an evidence that the sea 

 had been filling up to such an extent that here and there barriers 

 of various kinds were formed which restricted the free move- 

 ments of animal life which had prevailed before this time. These 

 barriers were, in part, shoal places over which the waves moved 

 with violence, thus destroying the quiet conditions necessary 

 for exuberance of life. In some places portions may even have 

 projected a little above the surface of the sea, particularly In] 

 late Richmond time. Probably also sediment-laden currents 

 from land surfaces which had emerged at no great distance pro- 

 duced areas in which the conditions were inimical to most forms 

 of life. 



In the Ohio-Indiana area conditions were usually propitious 

 for animal life. A large and varied fauna has been made known, 

 in which bryozoa and brachiopods predominate. The list of 

 bryozoa thus far described is here given as some of these forms 

 are known to occur in Kentucky and others will probably be 

 found. A very large number of species is known from all three
