The factual accuracy of 此地图 or the file name is disputed.
Reason: This paleotectonic map shows the plate tectonic configuration about 70 Ma ago but also shows the outline/silhouette of the present North American continent (e.g. Baja California only exists for about 5-10 Ma). Also, the map suggests that the western coast line of North America is identical to the subduction front of the continent, which, of course, it is not!
English: Plate distribution between 64 and 74 million years ago. Arrows represent direction of subduction along North America. Black represents present-day land area.
