Fouanoucyathus tafraoutiensis El Bakhouch & Kerner, n. gen., n. sp. (Figs 2-5) urn:lsid:zoobank.org:act: B5367302-7B81-4539-A744-818C17549559 ETYMOLOGY. — Named after Tafraout, the city from where the specimens were collected. TYPE LOCALITY. — Tafraout, Morocco. TYPE AGE. — Early Cambrian (Cambrian age 4 or Botoman). TYPE MATERIAL. — Morocco • 1 specimen; western Anti-Atlas, Tata Group, Issafen Formation, Tafraout, section FO.IS8; holotype: AA-FOU-CI-2 • 3 specimens; western Anti-Atlas, Tata Group, Issafen Formation, Tafraout; paratypes: AA-FOU-CI-1 from section FO.IS4; AA-FOU-CI-3 from section FO.IS10; AA-FOU-CI-4 from section FO.IS24. MEASUREMENTS. — See Table 2. DIAGNOSIS. — Intervallum 4-9 mm wide; outer wall with 3 to 5 vertical rows of canals per intersept; septa completely porous; some synapticulae grouped into synapticular tabulae (Fig. 2F, 3B, D); in cups of diameter 22-50 mm. DESCRIPTION Cup conical, diameter 22-50 mm with intervallum 4-9 mm wide, outer wall with 3-5 rows of canals (diameter 0.09-0.2 mm, lintels 0.06-0.07 mm, porosity coefficient 1.3-3.3), wall thickness (0.2-0.3 mm). Inner wall with one row of straight canal per intersept (diameter 0.4-0.7 mm, lintels 0.11-0.23 mm, porosity coefficient 1.9-6.4), wall thickness (0.6-1.2 mm). Septa are perced by numerous vertical pore rows, with the number varying from 6 to 21 rows; (perforation diameter 0.14-0.22 mm, lintels 0.17-0.34 mm) (Fig. 2C, 3B). Some synapticulae grouped into synapticular tabulae. RK 1.4-2.3. IC 1/4,0-1/9,0. GPC 1.1-1.9 REMARKS The canals on the inner wall for this new taxon are quite regular in size and shape (Fig. 5B) and their direction varies from horizontal to upward with all the intermediate directions. Septa are completely porous (6-21 rows) and their pores have round to slightly longitudinally elongate shape (Fig. 3C).
