Sand is a pretty good heat conductor. It’d probably be ok on hot nights, but not so much in winter.
it's a good thermal insulator! next time you are at the beach with hot sand, try digging down a few cm with your toes.
Good thing you can just cover it with a blanket or something in winter
You need more insulation than you'd expect. The coldest campsites I've ever had have all been on sand.
Since we're talking about stone age tech, would mammoth pelt offer good insulation?
Can't say I have a lot of experience sleeping on mammoth pelt.
A slightly more modern way to deal with cold sand is to bury some coals beneath the pelt, after using them to cook your dinner or whatever.
