Transapical Sutures in Dinoflagellate Cysts

Proceedings of the Annual Meeting. American Association of Stratigraphic Palynologists, 1972
Abstract Several lacustrine species of Pleistocene and Recent peridiniacean cysts form archeopyles by means of a single transapical suture, with or without accessory sutures. Previously published records of closely similar structures in marine Cretaceous peridiniacean cysts are documented and reinterpreted, and a further type is described from the ...

DINOFLAGELLATE CYSTS IN THE PLANKTON

New Phytologist, 1978
SUMMARYThe geographical and seasonal occurrences of dinoflagellate cysts at a depth of 10 m in the North Atlantic and North Sea are described from samples taken by the Continuous Plankton Recorder between June 1973 and December 1975. A special study was made of the large cyst of Polykrikos schwartzii Bütschli in the autumn of 1973 when CPR samples were

Fossil Calcareous Dinoflagellate Cysts

1991
Present knowledge of fossil calcareous dinoflagellate cysts is summarized briefly. All genera of the cyst family Calciodinellaceae Deflandre 1947, including most of the Mesozoic “Calcisphaerulidae” Bonet 1956, known from the fossil record since the late Triassic, are listed here and subdivided into three subfamilies.

Dinoflagellate cyst production in one-liter containers

Journal of Applied Phycology, 2004
Methods for the production of dinoflagellate cysts in two types of 1 L containers have been developed. Using these methods, dinoflagellate cysts can be produced in amounts large enough for shellfish grazing experiments or whenever large amounts of cysts are needed.

Limitations of dinoflagellate cyst transfer functions

Quaternary Science Reviews, 2006
Abstract Organic-walled dinoflagellate cysts have become an important proxy for reconstructing Quaternary sea-surface conditions, with transfer functions generating quantitative estimates of summer and winter sea-surface temperatures, salinity, and ice cover.

Calcareous Dinoflagellate Cysts as Paleo-Environmental Tools

1999
An overview is presented of the current state of knowledge on paleo-ecological aspects of calcareous dinoflagellate resting cysts. Apart from literature-based information, a discussion of new results is also provided from Equatorial Atlantic surface plankton samples, surface sediment samples and Late Quaternary sediments from two gravity cores.

D. -Les kystes de Dinoflagellés/ Dinoflagellate cysts

Géologie Méditerranéenne, 1979
L'étude des kystes de Dinoflagellés de la Mer Pélagienne montre cinq assemblages principaux dont quatre sont liés à la profondeur d'eau et un aux lagunes sursalées fossiles. Après la dernière régression glaciaire (27000 à 18000 ans BP), la transgression versilienne a atteint progressivement le niveau actuel avec deux poussées plus actives, l'une ...

A determination key for modern dinoflagellate cysts

Palynology, 2015
The first online modern organic-walled dinoflagellate cyst determination key has been launched at www.marum.de/dinocystkey.html. This key is based on easily recognisable morphological features of dinoflagellate cysts that can be observed using standard transmitted light microscopy.

Paleogene dinoflagellate cysts from Punta Prat, southern Chile

Palynology, 2009
Abstract Paleogene dinoflagellate cysts were recorded from the Chorrillo Chico and Agua Fresca formations at Punta Prat, southern Chile. Due to the presence of Palaeoperidinium pyrophorum, the Chorrillo Chico Formation is no younger than Late Selandian.
