The dinoflagellate Nannoceratopsis Deflandre; morphology, affinities and infraspecific variability
Micropaleontology (1961) 7 (3): 305-316

Abstract

"A reinterpretation of the morphology of Nannoceratopsis Deflandre 1938 is based on a study of many specimens of N. deflandrei Evitt n.sp. from the lower Jurassic (lias delta of Denmark--the first dinoflagellate to be described from the lower Jurassic. Nannoceratopsis is morphologically similar to Recent Dinophysiales, a group of dinoflagellates without a previously reported fossil record. The extreme infraspecific variability of the new species is analysed. Discovery of N. pellucida Deflandre, the type species, in the upper Jurassic of Utah provides the first record of the genus in North America."
