Cardipeltis wallacii

Pteraspidomorpha - Cardipeltidae

Taxonomy
Cardipeltis wallacii was named by Branson and Mehl (1931). Its type specimen is Numbers 601 and 602, Vertebrate Paleontology, University of Mis-souri, a skeleton (the natural mold of both the dorsal and ventral surfaces of a fairly complete dorsal shield), and it is a mold.

Synonyms
  • Cardipeltis sinclairi was named by Bryant (1933). Its type specimen is PU 13515, a partial skeleton (A dorsal shield in counterpart in grey limestone), and it is a 3D body fossil.

    It was synonymized subjectively with Cardipeltis wallacii by Denison (1966).
  • Cardipeltis oblongus was named by Bryant (1933). Its type specimen is PU 13514, a partial skeleton ( A dorsal shield in grey limestone), and it is a 3D body fossil.

    It was synonymized subjectively with Cardipeltis wallacii by Denison (1966).

Diagnosis
ReferenceDiagnosis
E. B. Branson and M. G. Mehl 1931Dorsal armor consisting of one subcardiform
or triangular plate of large size with length and width about equal
and orbital notches near midlength. The dorsal surface is marked by fine, closely crowded vermiform ridges. Ventral shield unknown.
R. H. Denison 1966The dorsal disc has a median length in known specimens of 132 -159 mm. The ratio of its maximum width to its median length is 1.05 to 1.15. The ratio of the greatest width across the anterior part of the disc to that across its postbranchial lobes is .73 to.78. Thebranchialnotchesareofmoderatedepth,andseparated from each other by 95 to 105 mm. The ornament of the dorsal disc consists of rather coarse ridges, generally radiating laterally and anterolaterally from the midline, but with many irregularities; the ridges are subdivided into tubercles near the margins, and occasionally over much—of the disc.
