Howard >> The Atlantic closed (with continental collision) first, then opened, as it continues to do today. The collision occurred during Devonian time, creating the mountains of the eastern US. The Atlantic started opening up again in Triassic time. << If this all happened…why do the continents fit so well together right now. I have done clay modeling on a globe and the continents fit almost perfectly together in their current shape. The edge of the continents are virtually a vertical break and they fit together now. This cannot be just a coincidence. It appears that the margins have not changed since the separation. How could all this change and additional coast be added and still they fit together? Kamron
