The Chicxulub crater formed nearly 66 million years ago. Is it surprising at all that the Chicxulub crater is still round enough today to be recognizable as a crater?  Where was it located before plate tectonics moved it to where it is now?

Continental-drift shifts the tectonic-plates more than squish them, so the circular-shape will be preserved.

True, but there are notable exceptions.  North America's Rocky Mountain range exists within the North American Plate, not at a plate boundary.  And the Yucatan peninsula exists relatively close to where the Caribbean Plate meets the North American Plate.

But I suppose that the existence of the approximately round Chixculub Crater means that location it did not see much distortion over the past 66 million years.
