Dingodinium spinosum
From dinoflaj3
?spinosum (Duxbury, 1977, p.46–47, pl.9, fig.3; text-fig.17) Davey, 1979c, p.60. Holotype: Duxbury, 1977, pl.9, fig.3; text-fig.17. Originally Parvocavatus, subsequently Dingodinium, thirdly (and now) Dingodinium?. Questionable assignment: Stover and Helby (1987d, p.282). This combination, as "Dingodinium spinatum", was not validly published in Fisher and Riley (1976, p.52), since these authors did not fully reference the basionym. Age: late Berriasian.
