... Actiniscus ). Regarding organic matter in general, the oxygen exposure time appears to have a strong influence on the preservation of organic-walled dinoflagellates. Here differences in the cyst-wall composition may lead to strongly biased assemblages. Cysts of phototro-phic gonyaulacoid taxa (e.g...

... translation of the german (“Scheibensternchen”), with which Ehrenberg already in 1854 meant, i.a. discoasters. Ehrenberg classified his “Scheibensternchen” in his genus Actiniscus. The type species of this genus, however, is a dinoflagellate with a siliceous skeleton (Loeblich and Tappan, 1966, p. 95...
