  eries, 
  but 
  it 
  is 
  now 
  evident 
  that 
  that 
  sedimentation 
  could 
  not 
  

   have 
  been 
  contemporaneous 
  with 
  the 
  uplifting 
  of 
  the 
  Arbuckle 
  

   region.* 
  The 
  orogenic 
  disturbance 
  which 
  resulted 
  in 
  the 
  rapid 
  

   accumulation 
  of 
  the 
  ten 
  or 
  twelve 
  thousand 
  feet 
  of 
  clastic 
  beds 
  

   composing 
  the 
  Stanley 
  and 
  Jackfork 
  cannot 
  be 
  included 
  with 
  

   the 
  "Culmides" 
  of 
  Chamberlin. 
  It 
  probably 
  was 
  a 
  feature 
  of 
  

   the 
  events 
  which 
  mark 
  the 
  transition 
  between 
  the 
  Waverlyan 
  

   and 
  Tennessean 
  systems 
  of 
  Ulrich. 
  Instead 
  of 
  one 
  great 
  

   orogenic 
  revolution 
  closing 
  the 
  Paleozoic 
  era 
  there 
  would 
  

   appear 
  to 
  be 
  at 
  least 
  four 
  such 
  disturbances 
  : 
  Waverlide, 
  Cul- 
  

   mide, 
  Hercynian, 
  and 
  Appalachian. 
  

  

  It 
  is 
  perhaps 
  significant 
  that 
  the 
  relation 
  between 
  the 
  epoch 
  of 
  

   refrigeration 
  implied 
  by 
  the 
  ice-borne 
  bowlders 
  in 
  the 
  lower 
  

   portion 
  of 
  the 
  Caney 
  shalef 
  and 
  the 
  Waverlide 
  disturbance 
  is 
  

   analogous 
  to 
  that 
  between 
  the 
  much 
  more 
  extensive 
  " 
  Permo- 
  

   Carboniferous" 
  glaciation 
  and 
  the 
  more 
  violent 
  Hercynian 
  revo- 
  

   lution. 
  

  

  Finally, 
  it 
  should 
  be 
  stated 
  that 
  the 
  third 
  leg 
  of 
  the 
  paleon- 
  

   tological 
  tripod, 
  the 
  evidence 
  accorded 
  by 
  vertebrate 
  fossils, 
  

   supports 
  the 
  conclusions 
  which 
  have 
  been 
  based 
  upon 
  the 
  

   invertebrate 
  remains. 
  According 
  to 
  Eastman 
  \ 
  the 
  character 
  of 
  

   the 
  Caney 
  fish 
  remains 
  indicates 
  their 
  Upper 
  Mississippian 
  

   age 
  so 
  far 
  as 
  the 
  evidence 
  goes, 
  though 
  it 
  is 
  admittedly 
  slight.
