Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. H. Denison 1970 | Pteraspids with each branchial opening well in advance of the posterior corner of the dorsal shield, opening dorsally, bounded anteriorly and laterally by a branchial plate, posteriorly by a large posterior cornual plate, and medially by a small anterior cornual plate. Dorsal shield of moderate width, and in life well arched. The rostral plate short and broad with a narrow ventral preoral surface. Dentine ridges typically coarse and knobby, or subdivided into elongate tubercles. | |
| E. Randle and R. S. Sansom 2017 | A Protaspididae with wide shield and branchial opening in advance of the posterior end of dor- sal plate; ornament of undulating tuberculated ridges; pre- oral field which lacks a pre-oral surface; rostral plate with rounded orbital notch; rostral plate well rounded anteri- orly and separated from the dorsal plate by an orbito- pineal belt; scale-like dorsal spine and scale-like cornual plates. |
