Answer 1

What happened to the theory that they all spent eons in shallow seas? That some mammals returned to a aquatic environment and were able to grow larger and simultaneously lost their heavy fur, elephants, hippos, rhinos, humans…
Couldn’t T-Rex and their prey been splashing around in 6’ of water taking the strain off their joints? Hippos have a complex life style mostly in water. The giant beaver of North America probably weren’t running through the forest but mostly hanging around in streams.
It’s really hard to be 10-20 tons without external support.
A T-Rex breast plate looks like my row boat and they ran like a duck swims. To run on two legs requires an upright posture or you’ll be zig zagging!
