Vendotaenia, a simple ribbon-like fossil, is classified within the informal vendotaenid group alongside morphologically similar fossils. These fossils, which are frequently encountered near the Precambrian-Cambrian boundary, have been hypothesized to possess potential for stratigraphic correlation. However, their taxonomy is often ambiguous and the occurrences in older strata challenge their biostratigraphic significance. In this study, we first report vendotaenid fossils from the Late Ediacaran Tabia Member of the Adoudou Formation in Morocco. Based on meticulous morphological examination of the abundant specimens, these fossils are identified into three distinct morphological taxa, including Vendotaenia, characterized by a constant width and smooth curvature; Tyrasotaenia, also of constant width but commonly folded and twisted; and the lanceolate form Lanceoforma. Furthermore, we have reassessed the related fossil reports within a comprehensive database to evaluate their spatiotemporal distribution. The result shows that all three fossil genera exhibit long temporal ranges with the first appearances predating the Ediacaran. Given their simplistic and often indistinguishable morphology, Vendotaenia and related vendotaenids are deemed unsuitable for stratigraphic correlation of the uppermost Ediacaran.
