Davis Strait proto-microcontinent

The Davis Strait proto-microcontinent is a failed microcontinent located in the Davis Strait between Greenland and Canada discovered in 2024.
It is roughly thick surrounded by a thinned out continental crust which is thick on each side. It is considered a proto-microcontinent because it is incompletely rifted and submerged. The separation of the Davis Strait proto-microcontinent coincides with a change in the orientation of tectonic spreading, which occurred between 58 and 49 million years ago.
