       The cedar mountain Formation is becoming increasingly well known for the presence of brachiosaurid sauropods,‭ ‬and aside from Cedarosaurus,‭ ‬Abydosaurus and Venenosaurus are also present in different Members.‭ ‬Another sauropod,‭ ‬Brontomerus is also known from the Cedar Mountain Formation.‭ ‬Cedarosaurus stands out from others by a number of features,‭ ‬but mainly the foreleg bones which are noted as being more gracile than the other genera there.
       As a brachiosaurid sauropod,‭ ‬Cedarosaurus was probably a browser of tall vegetation growing around the height of the tree canopy.‭ ‬This would have allowed it co-exist with other types of herbivorous‭ ‬dinosaurs such as ornithopod like Cedrorestes,‭ ‬Hippodraco and Iguanocolossus as well as armoured nodosaurs like Gastonia.
       A principal predator of Cedarosaurus may have been the large dromaeosaurid theropod dinosaur Utahraptor,‭ ‬fossils for which have been in the same areas dating from roughly the same time as Cedarosaurus.‭ ‬Bigger threats may have also come from large carcharodontosaurid theropods similar to Acrocanthosaurus which would have been roaming around what would become the United States back in the early Cretaceous.‭
