It is assumed like modern animals sauropods practice resource partitioning. Diplodocids like Apatosaurus and Diplodocus would feed lower while the Macromonians, Camarasaurus and Brachiosaurus feed higher in the canopy. Tooth wear for macromonian adults differs from what is found in diplodocids but the wear on immature camarasaurs is similar. This makes sense as young camarasasurs would have been feeding at the same height as diplodocids.

UHA Camarasaurus

Camarasaurus the most common North American sauropod. It browsed on leaves on high trees with 48 long, blunt cropping teeth.

Tiptoi and Carnegie Safari Camarasaurus

It had a large blunt head with a short face and big eyes. It stood higher at the shoulders than at the hips.

Carnegie Safari Camarasaurus supremus

There are at least three documented camasaur speices. The initial occurance in C. grandis. Later in the formation it coexists with C. lentus. C. grandis disapears and C. lentus continues. Both these animals are about the same size, 50 feet long with a range in individual animals.

GeoWorld Camarsaurus

In the last of the Morrison many different dinosaurs seem to get bigger as the climate changes to arid. C. supremus gets about 50% larger making it the heavist sauropod of the Morrison and 75 feet long.
