Diagnosis
ReferenceDiagnosis
W. L. Bryant 1933 The characters upon which this family is founded are as follows:
i. The exoskeleton is thin and contains no impressions of pineal, nasal, branchial or other organs except the eyes.
2. The cephalic shield consists of one piece, apparently originating from a single centre of growth.
3. The orbits are large and placed far back in deep lateral notches in the dorsal shield.
4. The superficial sculpture consists of numerous short, round-crested ridges. These do not follow the contours of the shield as in the Pteraspidee and Protaspide, but radiate in all directions from a point in the median line of the shield, behind the level of the eyes, apparently the focus of growth.
