The dinosaur paradox unravels on a growing Earth in two respects.
1) The lesser gravity on a smaller Earth permitting larger life sizes that could not survive today can no longer be disputed. However, gravity on a smaller Earth does not fully explain the size of gigantic dinosaurs. The largest recorded land life today is a 12 ton elephant killed in 1956. The largest life size permitted with a 50% reduction in gravity would be a dinosaur weighing 24 tons. How is that possible when the biggest dinosaur is reported to weigh 70 tons and aged at 100 MY?
2) It is only possible on a growing Earth because we are measuring dinosaur fossils which are minerals of any of the 8-elements that replace the dinosaur organic substances. These mineral replacements are increasing in size along with the rest of a growing Earth.
