The mountains were formed after tectonic plates had moved away from each other
The similarities provide evidence North America & Europe were connected when the mountains formed.
Similar rock samples were found on the ocean floor and at the two mountain ranges indicating that they both formed around the same time.
This evidence does not support the theory of continental drift.
Alfred Wegener used all of the following for evidence of his idea EXCEPT...

Similar fossils on different continents
Comparable modern weather patterns on different continents
Similar rock formations on different continents
