No, a standing rib roast, also known as prime rib, is a much better cut of meat and comes from an area just to the rear of the cross rib roast, also known as English roast. The cross rib roast is from the cut of beef known as "chuck", which is from the top of the forelimb, near where it meets the shoulder blades. The standing rib roast comes from the area of the ribs where they meet the rib cage (above the area of the rib cage where the "short plate" cut is). They really are not the same, and do not cook the same way. The cross rib roast is best braised, whereas the standing rib roast is best roasted. You should see a difference in the price, with cross rib roast being less expensive than standing rib roast.
