Head, M. J. & Mantilla-Duran, F., 2020. Atlanticodinium striaticonulum n. gen., n. sp., a widespread extant dinoflagellate cyst from the late Cenozoic, and its comparison with Atlanticodinium janduchenei (Head et al., 1989) n. comb. Marine Micropaleontology, 159, 101774, https://doi.org/10.1016/j.marmicro.2019.101774. Atlanticodinium n. gen. accommodates small- to medium-sized proximate dinoflagellate cysts with a spherical or subspherical central body having a nonfibrous wall with a smooth to finely ornamented surface bearing numerous, short, hollow, unbranched, nontabular, nonfibrous processes. The archeopyle is precingular, its margins having well defined angles. Atlanticodinium striaticonulum n. gen., n. sp. has a IP archeopyle, and distinctive short, distally closed processes with internal striations. This species has a confirmed Lower Pleistocene record, possibly extending to at least upper Lower Pliocene, and occurs widely in modern marine sediments.
