I haven't read this article but have an obvious question.
How do the authors know if there were other fragments which hit in the
Tethys sea if their subsequent craters were destroyed by subduction? Is it
the fact that the preserved craters are x distance apart and other fragments
"should" have hit in the Tethys sea if the pattern is to continue?
