This very interesting article explores a few possibilities to the sauropod mystery, and comes to the conclusion that the atmosphere was much thicker in the mesozoic era, allowing for extra buoyancy and less gravitational pull :

"To produce an effective buoyancy force on
dinosaurs the Earth's atmosphere would have to
be thick enough to have a density comparable to
the density of water. By summing the forces
acting on a typical dinosaur such as a
Brachiosaurus the density of the necessary
atmosphere is calculated as:
?F = ?S (1 - 1/S.F.)
where ?F is the density of the fluid, ?s is the
density of the substance submerged in the fluid
such as the dinosaur, and S.F is the scaling

Inserting into this equation a scaling factor
of 3.2 and an overall vertebrate density of 970
kg/m3, the Earth's atmospheric density during
the late Jurassic period can be calculated to be
670 kg/m3.

This says that to produce the
necessary buoyancy so that the dinosaurs could
grow to their exceptional size, the density of the
Earth’s air near the Earth’s surface would need to
be 2/3’s of the density of water.

It may be difficult for some people to imagine how
the Earth could have had such a dense
atmosphere. But nevertheless, the wonders of our
reality often exceed the limitations of many
people’s imagination. Esker’s Thick Atmosphere
Theory violates no property of science. It is the
correct solution."

Quite convincing
