Your thought process still puzzles me. Erosion is an amazingly powerful force. It may be slow, but once the Appalachians were taller than the Himalayas, and there used to be a tall range of mountains in the middle of Africa where today there is only veld. Soft matter such as rotting roots erodes much faster than rocks, just ask any farmer. At the time scale of continent building the dinosaurs were around the day before yesterday.
