Diagnosis
ReferenceDiagnosis
E. B. Branson and M. G. Mehl 1931An acanthaspid form, the thoracic capsule of which bears long rigid postero-laterally directed pectoral spines and a dorso-median crest or spine. The thoracic capsule is composed of a large number of small, irregular, more or less closely fused plates without ndications of the normal acanthaspid regional divisions of
the armor. The capsule was probably somewhat flexible in young individuals. The antero-lateral portions of the ventral shield form
the major part of the lateral spines and the rest is formed by antero- lateral extensions of the dorsal shield with which the ventral shield
is suturally united diagonally across the spine. The outer surface of
the capsule is marked with coarse tubercles.
