Dasycladaceae) from the Cenomanian deposits of the Island of Brač
Title: Two New Species of Calcareous Algae (Dasycladaceae) from
the Upper Dogger of Southern Dalmatia (Croatia)
Journal: Geologia Croatica
Volume: 45
Year: 1992
Pages: from 15 to 24
Number of references: 17
Language: engleski
Summary: Two new species of calcareous algae (Dasycladaceae) are
described. One - Salpingoporella croatica n.sp. is characterized by a
clyindrical skeleton and undivided, phloiophorous to partly vesiculiferous
ramifications, arranged in whorls. The other species - Uragiella ragusina
n. sp. also has a cylindrical thallus and ramifications arranged in whorls.
The shape of the ramifications, however, varies from nodular or tubecular
to a typically pyriform and more rarely, to the Uragiella type. The
ramifictions are often deformed, which is particularly visible in more
distal tangential sections. Both species are found in the same sample which
belongs, chronostratigraphycally, to the UpperDogger.

Title: Salpingoporella robusta n. sp. (Calcareous algee;
Dasycladaceae) from the Upper Barremian - Lower Aptian of Mt. Biokovo,
Croatia
Journal: Geologia Croatica
Number: 2
ISSN: 1330-030x
Volume: 46
Year: 1993
Pages: from 175 to 180
Number of references: 9
Language: engleski
Summary: Salpingoporella robusta n.sp. (Dasycladaceae) is
characterized by a narrow central cavity and comparatively thick calcareous
sleeve with large ramifications. The new species was found in deposits
which indicate a transitional subtidal-lagoonal to restricted shoal or back
reef environment of Upper Barremian or, possibly,Lower Aptian age.

Title: Dissocladella bystrickyi n. sp., a new calcareous alga
(Dasycladaceae) from Upper Triassic dolomites of Mt. Medvednica (northern
Croatia)
Journal: Geologia Croatica
Number: 1
ISSN: 1330-030x
Volume: 48
Year: 1995
Pages: from in to press
Number of references: 9
Language: engleski
Summary: Dissocladella bystrickyi n. sp. occurs in early diagenetic
Upper Triassic dolomites, that were deposited in tidal flat and tidal
chanell environments in the carbonater platform interior. The new alga,
assigned to the genus Dissocladella, is characterised by verticillate and
distally flatened primary ramifications which give rectangular pores and
bear 5-7 club-shaped secondaries each. Its stratigraphic position is
suposed to be within the Norian-Rhaetian time span.

Title: The Revision of Genera Physoporella STEINMANN and
Oligoporella PIA (Dasycladales, Green Algae)
Proceedings title: 6th International Symposium on Fossil Algae and Carbonate Platforms - ABSTRACTS
Language: engleski
Place: Ankara, Turska
Year: 1995
Pages: from 15 to 15
Meeting: 6th International Symposium on Fossil Algae and Carbonate Platforms
Held: from 09/18/95 to 09/22/95
Summary: The presence of single or double whorls is considered as
the main characteristic that separates Physoporella and Oligoporella,
because of its biological importance. Physoporella (STEINMANN 1903) emend.:
Thallus cylindrical with piriferous branches arranged in single whorls.
Oligoporella (PIA 1912) emend.: Thallus cylindrical with piriferous
branches arranged in double whorls. Each double whorl consists of two very
close whorls of branches. Physoporella karrerioidea (PIA 1935) is
transformed into the new genus Ardeiporella n. gen.: Thallus cylindrical
with thick calcareous skeleton and narow central cavity. Verticillate
branches each consisted of "neck, head and bill".
Keywords: calcareous algae, Dasycladales, Permian, Triassic, systematics
