Add a one-line explanation of what this file represents
?
The factual accuracy of this map 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!
This image was uploaded in the JPEG format even though it consists of non-photographic data. This information could be stored more efficiently or accurately in the PNG or SVG format. If possible, please upload a PNG or SVG version of this image without compression artifacts, derived from a non-JPEG source (or with existing artifacts removed). After doing so, please tag the JPEG version with {{Superseded|NewImage.ext}} and remove this tag. This tag should not be applied to photographs or scans. If this image is a diagram or other image suitable for vectorisation, please tag this image with {{Convert to SVG}} instead of {{BadJPEG}}. If not suitable for vectorisation, use {{Convert to PNG}}.
