<span style="font-family: Times New Roman; font-size: small;"> </span><p class="MsoNormal" style="margin: 0cm 0cm 0pt; text-align: justify; line-height: 200%; text-justify: inter-ideograph;"><span style="mso-ansi-language: EN-GB;" lang="EN-GB"><span style="font-size: small;"><span style="font-family: Times New Roman;">From Palaeozoic (mainly Devonian) shallow-water carbonates, spherical to irregular shaped microfossils with thin, apparently homogeneous or perforate micritic walls are widely reported. They are classically referred either to unilocular parathuramminid foraminifera, algae incertae sedis or calcispheres (e.g., <em style="mso-bidi-font-style: normal;">Bisphaera</em>,<em style="mso-bidi-font-style: normal;"> Cribrosphaeroides</em>,<em style="mso-bidi-font-style: normal;"> Uslonia</em>,<em style="mso-bidi-font-style: normal;"> Vermiporella myna</em>, <em style="mso-bidi-font-style: normal;">Irregularina</em>). Due to their morphology and microstructural features, they are here reassessed more accurately as belonging to <em style="mso-bidi-font-style: normal;">Thaumatoporella</em> PIA, a widespread Mesozoic-Early Cenozoic taxon of incertae sedis showing a remarkably high morphological variability. In analogy to Mesozoic thaumatoporellaceans, <em style="mso-bidi-font-style: normal;">Bisphaera</em> <em style="mso-bidi-font-style: normal;">malevkensis</em> BIRINA is interpreted as the cyst (= resting) stage of forms ascribed to different genera, i.e., <em style="mso-bidi-font-style: normal;">Cribrosphaeroides</em>, <em style="mso-bidi-font-style: normal;">Uslonia</em> and <em style="mso-bidi-font-style: normal;">Vermiporella</em> (here: <em style="mso-bidi-font-style: normal;">Vermiporella myna</em> WRAY). This new interpretation leads to taxonomic reassessment as <em style="mso-bidi-font-style: normal;">Thaumatoporella malevkensis </em>(BIRINA) nov. comb. As a consequence of our interpretation, the rather long Mesozoic to Early Cenozoic (Ladinian to Early Ypresian) record of thaumatoporellaceans is supposed to be significantly larger than formerly assumed, showing<span style="mso-spacerun: yes;"> </span>four periods of increased abundance in the Middle/Late Devonian, Late Permian (?), Early/Middle Jurassic and Late Cretaceous time windows. </span></span></span></p><span style="font-family: Times New Roman; font-size: small;"> </span>
