Bullialdus may have a composition distinct from the surrounding region and the central peak has a height of 1000 meters and a depth of 3.5 km.
Moon is the best preserved laboratory and accessible to study impacts, which are the most important historical data from the Solar System. On Earth, which was struck by bodies four billion years ago, wind and rain erosion has degraded craters, making them difficult to study. On the Moon, however, these craters are well preserved.
Smaller craters in images that "fall" below Bullialdus, I think they are the same age, and Bullialdus T, was once a large crater, but was subsequently flooded by the lava of Mare Nubium, as Lubiniezky (44 km), also . From this we understand that Bullialdus is from an impact after Mare Nubium was formed.
