5 The upper part of the Mancos in the Rio Puerco field yields the same fauna as that 

 of the lower part of the Mancos farther east. In order to show the differences in age, 

 the column denoting upper Mancos in the Rio Puerco field is placed next to that de- 

 noting upper Mancos in the Cerrillos field.
