This is chalk on paper — the kind of sheet that was a step towards something else rather than the thing itself. He's said to have burned a lot of his own drawings late in life, supposedly so nobody would ever see the working-out behind the finished stuff. Ones like this got out anyway, and now they're framed and lit the same way the paintings are.

This is one of several studies Michelangelo made while working out the Libyan Sibyl for the Sistine Chapel ceiling — the same sheet has more sketches on the back, including a small seated figure that never made it into the fresco. Apparently he drew from a male studio model even though the finished sibyl reads as a woman, which is why the anatomy here looks so unmistakably male.
