... and recrystallization allowed micropaleontologic study by thin section only. The microfauna includes radiolarians, ostracods, echinoderm debris, and unidentified biogenic grains as well as calpionellids and nannoconids, but only the last two are persistently common. Calpionellid taxa include Amphorellina subacula...

...J. W. Murray; F. J. R. Taylor ABSTRACT Thin sections of limestone from the Upper Devonian Waterways Formation from the subsurface of Alberta, western Canada, reveal the presence of calpionellids, the fossilized loricas (tests) of ciliate protozoa. They are described as Vautrinella devonica sp. nov...

... Abstract Often grouped with the tintinnids (pelagic ciliate protozoans of the subclass Spirotheca), although modern tintinnids are organic-walled and calpionellids had calcareous walls. Thus, calpionellids are grouped by other workers as Protozoa incertae sedis . Calpionellids — Late...

.... Consequently, a current summary is offered here. The most useful taxa of the Tamaulipas are calpionellids, nannoconids, calcisphaerulids, micro-calamoidids, and planktonic foraminifers. For each of these taxa, general properties, illustrative and significant species, and important ranges are given...

... on calpionellids and ammonite zonation, the sequence stratigraphic interpretation can be correlated with the established eustatic chart. Clay mineral assemblages are characterized by a shift in the kaolinite content, recorded at the end of the calpionellid zone B, at the early/middle Berriasian boundary, at a time...
