﻿FOSSIL-WOOD 
  GROUP. 
  67 
  

  

  at 
  the 
  period 
  when 
  the 
  highest 
  portion 
  of 
  the 
  fossil- 
  wood 
  sand 
  was 
  being 
  

   formed. 
  No 
  traces 
  of 
  boring 
  molluscs 
  were 
  noticed 
  by 
  me 
  in 
  the 
  

   few 
  pieces 
  of 
  fossil-wood 
  contained 
  in 
  the 
  above 
  mammaliferous 
  gravels, 
  

   of 
  admitted 
  marine 
  origin 
  ; 
  but 
  it 
  is 
  reasonable 
  to 
  suppose, 
  that 
  the 
  

   conditions 
  of 
  a 
  marine 
  gravel 
  bank, 
  containing 
  rolled 
  limb-bones 
  of 
  the 
  

   larger 
  mammalia, 
  would 
  not 
  be 
  favorable 
  to 
  the 
  presence 
  of 
  wood-boring 
  

   molluscs, 
  and 
  that 
  to 
  the 
  turbulence 
  of 
  the 
  conditions 
  under 
  which 
  these 
  

   rolled 
  fragments 
  of 
  wood 
  became 
  embedded, 
  is 
  to 
  be 
  attributed 
  the 
  fact 
  

   of 
  none 
  of 
  them 
  being 
  perforated 
  or 
  bored. 
  

  

  This 
  upper 
  sand 
  is 
  generally 
  horizontal 
  ; 
  but 
  in 
  some 
  places 
  it 
  has 
  

   clearly 
  suffered 
  disturbance 
  and 
  partial 
  elevation, 
  though 
  the 
  newest 
  

   group 
  within 
  the 
  province 
  except 
  the 
  alluvium. 
  One 
  of 
  the 
  few 
  instances 
  

   noticed 
  by 
  me 
  of 
  a 
  decided 
  dip 
  in 
  this 
  group, 
  occurs 
  between 
  Omouk 
  and 
  

   Lema, 
  nineteen 
  miles 
  East-south-east 
  from 
  Thayet-mio. 
  A 
  bed 
  of 
  coarse 
  

   conglomerate 
  subordinate 
  to 
  this 
  sand 
  is 
  here 
  seen 
  dipping 
  at 
  30° 
  to 
  

   South-east. 
  In 
  this 
  conglomerate, 
  among 
  other 
  bones 
  rolled 
  and 
  in 
  poor 
  

   condition, 
  I 
  noticed 
  the 
  tusk 
  of 
  a 
  small 
  Elephant, 
  but 
  in 
  too 
  friable 
  a 
  

   state 
  to 
  admit 
  of 
  its 
  extraction. 
  The 
  following 
  fossil 
  bones 
  occurred 
  to 
  me 
  

   in 
  the 
  Prome 
  district 
  : 
  — 
  

  

  Ursus 
  ? 
  (Helarctos). 
  

  

  ... 
  A 
  single 
  canine 
  tooth. 
  

  

  Elephas. 
  

  

  ... 
  Lower 
  jaw, 
  tusk, 
  and 
  sundry 
  fragments 
  of 
  

  

  

  limb-bones. 
  

  

  Cervus. 
  

  

  ... 
  Part 
  of 
  lower 
  jaw. 
  

  

  Ruminant. 
  

  

  . 
  . 
  . 
  Metacarpal 
  bone 
  of 
  a 
  small 
  species. 
  

  

  Emydinse. 
  ... 
  

  

  ... 
  Two 
  species. 
  

  

  To 
  this 
  meagre 
  list 
  I 
  may 
  add 
  the 
  few 
  fossils 
  which 
  have 
  been 
  pro- 
  

   cured 
  from 
  Ava 
  from 
  a 
  similar 
  position 
  geologically.
