Why did these giants appear around the mid Cretaceous? Because there was
ample dry inland habitat? The Cenomanian transgression is said to have
reduced the latter, to the detriment of sauropods in North America.
Bruhathkayosaurus is Maastrichtian. Then there's the huge
Kimmeridgian-Tithonian Morrison diplodocids, and the large Early Jurassic
Moroccan femur and footprints...
