No, they are younger. Pangaea formed about 300 million years ago and began to break up around 180 million years ago. The Rockies were formed between 80 and 35 million years ago.
Velociraptors lived during the Cretacous, 80 million years ago.
The eastern mountains are older. The Appalachians formed between 300 million and 250 million years ago. The Rockies formed between 80 million and 50 million years ago.

The Intermountain Region lies between the Rockies and the Sierra Nevada mountain ranges. The Rocky Mountains formed 80 to 55 million years ago, while the Sierras date back to 250 to 200 million years ago.
I am not sure how long giant tree ferns have existed, but ferns have been around since the mid Devonian, about 380 million years ago. Palm trees first evolved about 80 million years ago, during the Cretaceous. Ferns diversified during the Cretaceous, and palms diversified by 60 million years ago, just after the extinction of the dinosaurs.
