That is a good question, I assumed the crater would have been a lot deeper and it's still there but has been covered by sand over the years
It wouldn't take a very big meteor to make a crater that size as it would be travelling very fast.
Maybe as small as a few 10s of metres. So could have fragmented on impact.
If it was a metallic meteor it would probably have been scavanged by early humans.

But that crater shape shows it must have struck from directly overhead (as opposed to a teardrop or long scar that you would get if it came in at an angle)

Impactors tend to make a fairly circular impact crater even when coming in from quite an oblique angle, there are exceptions on bodies with low/atmosphere but if you have a look at the moon more than 95% of craters are circular, even though they come in from many different angles.
