The Chain of craters on Mare Frigoris caused by a single asteroid? - Telescope images

A chain of craters that pass near the west of the giant crater W. Bond is seen in video capture images in this article. The chain of craters (see photo below to see where it is), starts with large craters and ends with the smallest one (Aristoteles A).

When I see these chain craters which diminishes in size, I wonder if they have a single source, a single body that disintegrated before touching the lunar surface.

 A good example is the comet Comet Shoemaker-Levy 9 (D/1993 F2 official), a the comet that disintegrated before reaching Jupiter (crashed in July 1994, providing the first direct observation of an extraterrestrial collision of solar system objects).

So these lunar craters below, that I listed from largest to smallest, I think that comes from the impact of a single body that disintegrated, causing a chain:
-Anaxagoras (51 km) attached to the western edge of Goldschmidt
-Epigenes (55 km) located northwest of W. Bond
-Timaeus (33 km) which is located at the southwest edge of W. Bond, on Mare Frigoris
-Archytas (32 km) which is on Mare Frigoris

-Protagoras (22 km) which is on Mare Frigoris
-Aristotle A It is the small crater in the chain, and that on Mare Frigoris

Anaxagoras and Epigenes craters in my opinion, could be caused from the impacts of individual asteroids, although I do not think so, but these have as source a single fireball that disintegrated before meeting with the lunar surface.
