“…Our single good specimen has cells somewhat smaller (c. 70 mm, as opposed to 100 mm) than the type material, but is otherwise very similar. Halysis was recorded by Guilbault et al (1976) and Poncet (1986) from the Ordovician of eastern and north-eastern Canada respectively. Guilbault et al (1976) regarded Flabellia Shuysky as a junior synonym of Halysis.…”

But many gaps remain and the radiation of Ordovician calci®ed algae and cyanobacteria is still only understood in outline (Johnson 1961).…”

ABSTRACT. Boreholes between Kuqa and Korla, in the northern Tarim Basin, Xinjiang, penetrated Ordovician marine limestones at depths of 5±6´2 km. From three boreholes 54 out of a total of 170 limestone samples contain calci®ed algae, cyanobacteria and associated Microproblematica. Calci®ed cyanobacteria (Girvanella, Botomaella, ?Subti¯oria) account for 37 per cent of occurrences; green algae (Dasyporelleae and Vermiporella) 28 per cent; Microproblematica (Nuia, Bevocastria, Rothpletzella, Halysis) 20 per cent; and`solenoporaceans' 15 per cent Girvanella and Nuia are common in the Early Ordovician deposits, and`solenoporaceans' are abundant in the Mid-Ordovician. Dasyporelleae and Vermiporella are most abundant in Mid±Late Ordovician samples. Calci®ed cyanobacteria are common throughout the limestone succession, but particularly in the Mid-Ordovician part. Moniliporella, Contexta, Plexa, Texturata, and Villosoporella, hitherto placed in the supposed red algal family Moniliporellaceae Gnilovskaya, are here regarded as dasycladalean green algae. Despite some omissions, this Tarim ora broadly resembles others from Kazakhstan, Baltica and North America, indicating the generally cosmopolitan nature of Ordovician calci®ed algae and cyanobacteria.

“…The thick, ceritral thread is found in the oldest codiacean, Palaeoporella of Cambrian to Devonian age. Codiaceans without a main medullary thread appeared and diversified during the Ordovician (Guilbault and Mamet, 1976;Wray, 1977). Dasycladaceans also originated during the Cambrian and were already diverse at that time (Endo, 1961;Wray, 1977).…”

“…Identification of the algae was based on the descriptions and systematic studies of Fritsch (1945), Johnson and Konishi (1956), Veevers (1970), Mamet and Roux (1974, b, 1977, 1978), Gayral (1975), Guilbault (1975), Mamet and others (1979), and Mamet and Martinez (1981).

Abstract: Description and illustration of 15 Ordovician Codiaceae from the St Lawrence Lowlands (Quebec and Ontario). Two genera (Lowvillia and Dimorphosiphonoides) and five species (Dimorphosiphonoides lesperancei, D. hofmanni, Lowvillia grandis, L. raripora, and L. multipora) are new.
