Trilobite is 12 mm long
Haragan Formation, Coal County, Clarita, Oklahoma
Remarks: The species is named after Bob carroll, who has worked the
Oklahoma Haragan Formation for more than a quarter century - he is
truly a master trilobite preparator. has worked on Oklahoma trilobites
for some 25 years now (see photo of bottom
of
piece).
If you think Cyphaspis carrolli looks like Cyphasis'
from Morocco, you would be correct. The reason
is a striking example of trilobite
paleogeography.
