I noticed this elusive feature in [http://www2.lpod.org/wiki/September_20,_2011 two] [http://www2.lpod.org/wiki/September_12,_2011 recent] LPODs - did you? Between Eudoxus (left) and Lacus Mortis (mostly out of view to the right)<br />
is the remnant of a likely old crater about 75 km wide. It has been filled in with ejecta from Imbrium, Eudoxus and perhaps the Lacus <br />
Mortis crater. It is nearly completely covered, with only pieces of its rim rising above the debris. If it were a fresh crater the fill must be <br />
4 to 5 km deep. I called it an old crater, and it is probably older than 3.8 b.y., Imbrium's age, but it may have been quite fresh looking <br />
when inundated so that it's ageing was instantaneous. Consdiering that maria cover about 17% of the nearside, and thick basin ejecta <br />
may have buried another 5-10%, there have been many lunar craters that have long since been erased. A few like this are relicts of <br />
another time.<br />
