There are many mysteries associated with the dinosaurs. Not only were they way too large to have lived under current gravity and inertia conditions, they sometimes migrated in ways impossible on today’s Earth.
Dinosaur fossils found in China are often remarkably similar to those found on the west coast of America.
The fossil records strongly suggest that dinosaurs could roam freely between America and China.
This is impossible to explain using conventional plate tectonics which has a huge ocean separating America and China in the time of the dinosaurs.
However, on an expanding Earth, where oceans first appeared during the age of the dinosaurs, the migration paths are no mystery at all.
