A NEW SUNWAPTAN (LATE CAMBRIAN) TRILOBITE FAUNA FROM THE UPPER MISSISSIPPI VALLEY
|
ABSTRACT
A single bed at the base of the Jordan Sandstone in a road cut at Arcadia, Wisconsin, yielded an undescribed Late Sunwaptan (Saukia Zone) trilobite fauna that includes at least four species from the families Dikelocephalidae Miller, 1889 and Eurekiidae Hupe, 1953. Arcadiaspis bispinata n. gen. and sp. is a distinctive eurekiid that is characterised by paired occipital and thoracic axial spines, long genal spines, and a nonspinose pygidial margin. Other genera present are the d...
