Evaluate: Of the fossils presented in this Gizmo, Homo floresiensis is the youngest. In the Coccocephalus fossil, the cranial nerves are intact inside the braincase but disappear as they exit the skull. Draw conclusions: Compare the data you collected in activity A with the data you collected in this activity. Vocabulary: bipedal, canine, cranial capacity, cranium, evolve, foramen magnum, hominid, hominin, inde... [Show more]. An important index for measuring hominid skulls is the opisthion index.
