Diagnosis
ReferenceDiagnosis
R. Köhler 1995P. terrypratchetti had a body armour made up by numerous
smooth platelets which did not show any sculpturing, e.g. keels. The
concave proximal dorsal face of the second and third rib carried a
median keel. Thoracic vertebrae showed thin neural arches which
were perforated by nerve foramina.
