  more 
  in 
  thickness 
  at 
  the 
  base 
  of 
  which 
  are 
  rounded 
  concretions. 
  

   From 
  this 
  sandstone 
  to 
  the 
  top 
  of 
  the 
  cliff 
  shales 
  are 
  found. 
  The 
  

   middle 
  of 
  the 
  cliff 
  is 
  on 
  a 
  level 
  with 
  the 
  railroad 
  track 
  on 
  the 
  south 
  

   side 
  of 
  the 
  river. 
  These 
  rocks 
  are 
  quite 
  fossiliferous 
  and 
  belong 
  in 
  

   the 
  Ithaca 
  formation. 
  The 
  species 
  listed 
  below

  Along 
  Otsdawa 
  creek 
  at 
  the 
  narrows 
  one 
  mile 
  north 
  

   of 
  Otego 
  village 
  is 
  an 
  interesting 
  exposure 
  because 
  the 
  passage 
  

   from 
  the 
  top 
  of 
  the 
  Ithaca 
  formation 
  into 
  the 
  Oneonta 
  sandstone 
  

   is 
  clearly 
  shown. 
  The 
  level 
  of 
  the 
  creek 
  at 
  the 
  highway 
  crossing 
  

   east 
  of 
  Otego 
  on 
  the 
  river 
  road 
  is 
  only 
  about 
  five 
  feet 
  lower 
  than 
  

   the 
  railroad 
  level 
  but 
  from 
  this 
  point 
  to 
  the 
  next 
  bridge 
  across 
  

   the 
  creek 
  on 
  the 
  north 
  road 
  where 
  the 
  top 
  of 
  the 
  Ithaca 
  forma- 
  

   tion 
  is 
  reached 
  there 
  is 
  a 
  rise 
  of 
  51 
  feet. 
  By 
  the 
  side 
  of 
  the 
  creek 
  

   at 
  this 
  bridge 
  about 
  three 
  feet 
  of 
  shales 
  are 
  exposed 
  which 
  con- 
  

   tain 
  a 
  few 
  fossils 
  but 
  most 
  of 
  the 
  specimens 
  are 
  poorly 
  preserved 
  

   and 
  the 
  fauna 
  is 
  meager. 
  The 
  list 
  is 
  as 
  follows:

   Above 
  these 
  shales 
  the 
  rocks 
  are 
  covered 
  for 
  three 
  feet, 
  then 
  

  

  there 
  is 
  a 
  ledge 
  of 
  thin 
  sandstone 
  and 
  shales 
  two 
  feet 
  thick. 
  

  

  On 
  the 
  bank 
  of 
  the 
  creek 
  at 
  this 
  locality 
  above 
  the 
  shale 
  and 
  

   sandstone 
  the 
  rocks 
  are 
  concealed 
  for 
  10 
  feet; 
  but 
  a 
  little 
  farther
