The biggest land animal today is the elephant. To walk around it got those legs like columns to support the massive weight. How it was possible for animals sometimes 5 times bigger than a elephant to stand and walk?
For me something is very wrong about it. I allready asked experts in conferences and they simple ignore me.
I have only 2 explanations . Or the gravity was smaller than today or the flesh and bones were lighter.
When we see those slender animals with, sometimes, legs like land birds it is difficult to imagine them running around in our Earth today. The some applies to the flying pterodactyls when compared to the condor.
Any ideas?
