Auloblastus, a new blastoid from the Mississippian Burlington limestone
Harold Hartman Beaver
Auloblastus clinei, a large spiraculate blastoid from the Upper Burlington of southwestern Missouri, differs from other blastoids in a combination of morphologic features, including the number of hydrospires, the radial-deltoid relationship, and the lack of a hydrospire plate. Two previously undescribed passageways, the lateral canals, are recognized; these canals parallel the median groove and are excavated into lancet and side-plate material along the lancet-side plate suture.
