No. Stegosaurus stenops lived in the Late Jurassic (155-150 Ma) in North America. Spinosaurus aegyptiacus lived in the Early Cretaceous (~100 Ma) in North Africa. Separated by 50 million years and two continents, they never coexisted. Spinosaurus fed mainly on giant fish like Onchopristis, not large terrestrial dinosaurs.
Spinosaurus, by a wide margin: 7 to 14 tonnes at 14 to 15 metres, against 2.5 to 4 tonnes and 7 to 9 metres for Stegosaurus. Spinosaurus aegyptiacus is the longest known land carnivore, but it fished the rivers of North Africa — a North American plated herbivore was never on its menu.
Because the question keeps coming up, driven by games and films. Stegosaurus dies out around 145 million years ago; Spinosaurus appears only at 95 million years, on another continent. Fifty million years and an ocean separate them. Comparing their stats stays instructive, provided one says plainly that no encounter ever happened.
