If it was that of the carinate birds, how did the struthious birds and Dinosauria independently agree to differ?
To this type of struthious, or running bird, the name Dromornis has been given.
The 1st is the struthious, or Ostrich order, or those which never rise from the earth.
Notwithstanding their relatively large size, struthious birds do not reach great ages.
But besides this general evidence we have direct proof that the struthious birds had a wider range in past times than now.
It must have been that of the struthious birds or that of the carinate birds, or something different from both.
The wings of struthious birds differ from those of the Carinatae, just described, in many ways.
In both ostrich and Rhea, as well as in all the other struthious birds, the under surface of the wing is entirely bare.
