In vertebrates, the endoskeleton system is further divided into the axial skeleton and appendicular skeleton. Speculations on the digestive system of early vertebrates are based mostly on comparisons of their skeletal remains, habitat, and environment with those of present-day species. Morphological divisions—endoskeleton vs. exoskeleton From the perspective of comparative morphology, including paleontology, it has been suggested that two lineages of skeletal systems—the endoskeleton and exoskeleton—have succeeded in vertebrate evolution (Figure 1, Table 1) [7,11]. In this laboratory exercise, you will examine vertebrate specimens representative of three skeletal systems: 1) the skull, 2) the limbs, and 3) the spine. From the perspective of comparative morphology, including paleontology, it has been suggested that two lineages of skeletal systems—the endoskeleton and exoskeleton—have succeeded in vertebrate evolution (Figure 1, Table 1) [7,11].
