The heads of prosauropod and sauropod dinosaurs appear to be small, compared with those of extant endothermic mammals. This has been considered inconsistent with the hypothesis, supported by several other anatomical characteristics, that these animals had cellular metabolic rates significantly above the usual reptilian level. However, prosauropods and sauropods had only moderately developed cranial musculature, comparable with that of more typical reptiles. This musculature is plesio‐morphic… CONTINUE READING
