Little bit dataisincomplete.
With the ice ages and the rising and falling of continents, this is kind of incomplete due to the lack of deep sea bathymetry. Not to mention the straight up ice impact or ocean impacts we could have had. If the world was always roughy 70% water, then this represents far less than half of all the impacts, and many of them would have been insane tsunamis.
A bunch of much older ones could have formed the current Black Sea or Gulf of
MexicoAmerica.Not only that, but there are no craters in South America, and virtually none in Africa except for South Africa. Also none in South Asia or China. That could be a coincidence, it could also be those areas aren’t as widely prospected yet.
