zoobank.org/ DA607E3F-F49B-47CC-A605-E821FC00F3ED

Etymology. Similar to Orthovertella Cushman and Waters, 1928a .

Synonym. Orthovertella (pars).

Type Species. Orthovertellopsis proteaeformis n. gen. n. sp.

Diagnosis. Free Calcivertellidae ? characterised by a large coiled initial coiled stage followed by a very short uncoiled, rectilinear last stage.

Composition. Orthovertellopsis proteaeformis n. gen. n. sp.; O. calcitornellaeformis n. gen. n. sp.; Orthovertella? simplicissima Miklukho-Maklay, 1968 ; Midiella glomospiroidalis ( Sosipatrova, 1972) sensu Blazejowski, 2009 , figure 16.12; Hemigordius hyrnefjelleti Blazejowski, 2009 ; H. sp. sensu Blazejowski, 2009, figures 15.8-12, 16.13- 14; H.? sp. sensu Blazejowski, 2009, figure 15.7; Hemigordiopsida indet. sensu Blazejowski, 2009, figure 15.13-15; Orthovertella protea sensu Crespin, 1958 ; O. protea sensu Foster, Palmieri and Fleming, 1985 ,? Orthovertella sp. 1 sensu Lambert et al. (2002, plate 7, figure 28);? Graecodiscus praecursor Nestell and Nestell, 2006 ; and? G. sp. 2 sensu Nestell and Nestell, 2006.

Comparison. Orthovertellopsis n. gen. differs from Orthovertella by a terminal stage less developed, a more regular coiling, and differs from Calcitornella by a more regular coiling and a free habitat indicated by the absence of an attachment plane face.

Occurrence. Kungurian (late Leonardian) of New Mexico. Early Permian of Australia (Carnarvon Basin, Canning Basin, Tasmania, and perhaps Sydney Basin). Permian of South China. Early Kazanian (Middle Permian) of the Urals.?Latest Guadalupian of Texas.
