How would endo-skeletal systems adapt to the atmospheric pressures given?

Surface gravity:

• 1G

Info regarding of altitude, pressure, and atmospheric density:

altitude    pressure    density 
(meters)    (atm)       (kg/m^3)
0           17          10 
1000        15.3        9
2000        13.8        8.1
3000        12.5        7.3
4000        11.3        6.6
5000        10.1        6
10000        6          3.6
15000        3.6        2.1
20000        2.2        1.3
30000        0.8        0.5
40000        0.3        0.2
50000        0.1        0.06

What adaptations would endo-skeletal systems have based on higher atmospheric pressure but earth-like gravity. Could the bones be slimmer, could they be pneumatic / hydraulic? Could they be looser? Could they have a special external coating? Would they be supported better by higher pressures thus making bones slimmer? Etc. NOTE: The data for my atmosphere may not be entirely correct, but nonetheless, that's not my focus here, my focus is how this much of an atmospheric pressure AT the surface would have impact on the evolution of endo-skeletal systems.
