Abstract

: The paper concerns all Eocene anascan Bryozoa known from Slovakia. New bryozoan associations from

Štrba and Poluvsie are studied and described. A total of 10 taxa, newly found in Slovakia are described, the remainder
are listed.

Key words:

Western Carpathians, Eocene, Bryozoa, Anasca, systematics.

Introduction

This paper concerns anascan Bryozoa from Eocene sedi-
ments, in the Slovak part of the Western Carpathians (Fig. 1).
The associated fieldwork (done within the last two years)
was aimed at finding new bryozoan localities not described
in the previous paper of Zágoršek (1994). Two localities —
Štrba and Poluvsie yielded bryozoan associations.

The bryozoan zoaria mostly occur in well lithified marls.

Several techniques have been used to have specimens with
observable surface. Most of the techniques are aggressive,
which caused bad preservation of the fossils. However, most
of the specific features have been preserved and could be ob-
served. Some of the found specimens cannot be listed under
any known species, but due to the bad preservation, no new
species could be erected.

Most of the Eocene anascan Bryozoa from the Slovak part

of the Western Carpathians have been published already
(Zágoršek 1996a,b). The remainder are described here.

The holotypes and paratypes of Reuss species as well as of

Stoliczka species have been studied in the Vienna Natural
History Museum in 1996. The original material has been
compared with the material from Slovakia. All observations
are commented on, in the “Remarks” within the description
of the species.

Description of the localities

The Eocene sediments of the Western Carpathians can be

divided into four formations (Gross et al. 1984). The studied
bryozoans are from the basal Borové Formation (Východná,
Partizánska upča, Hybica and Štrba) and from the Zuberec
Formation (Rajecké Teplice and Poluvsie).

The lithological content of the Borové Formation in the

Liptov Basin is rather varied (Gross & Köhler 1980). It con-
sists of fine-grained calcarenites (Východná), or of
yellowish-brown organodetrital clayey limestone (Partizáns-
ka upča). Within the formation, there are a thin-bedded,
pale-grey to brown bryozoan limestones (Hybica and Štrba).

The locality at Východná (Fig. 2) is situated east of the

village, in a road-cut near the railway station. The fossils
(nummulites, bryozoans and rare molluscs) occur in an orga-
nodetrital limestone. Among them are Nummulites garnieri
Boussac and N. chavannesi de la Harpe, from which an
Eocene age has been determined (Gross & Köhler 1980). The
locality probably represents a shallow marine environment.
This can be confirmed by the occurrence of the bryozoan
genera Lacrimula and Lunulites which lived only in shallow
marine conditions in the Eocene (Braga & Munari 1972).

The locality at Partizánska upča (Fig. 3) is in an aban-

doned quarry lying about 1.6 km south of the village. Fora-
miniferal tests (Discocyclina prattii (Michelin 1846) and
Nummulites chavannesi

de la Harpe) dominate over other al-

lochems in the sediment. Nummulites chavannesi determines
the Eocene age (Gross & Köhler 1980). As in the locality Vý-
chodná, the large quantity of large forams as well as the pres-
ence of Lacrimula point to a shallow marine environment.

The locality called Hybica (see Fig. 2) is situated on the

right bank of the Hybica River, about 3.4 km north of the vil-
lage of Východná. The outcrop represents the upper part of a
biogenic (mostly algal) buildup. Bryozoan marl occurs as a
lensoid body, probably formed by a slump, in the claystone
of the Huty Formation. According to Zágoršek (1996) the
original sedimentation area of the bryozoan marls could be a
shelf margin with cool water due to the influence of up-
welling. Later, marls with bryozoans probably slumped to-
ward the basin and into deeper sediments.

The Štrba locality lies in the abandoned railway cut, about

100 m north of Kolombiarok Hill (899.6 m) and about 800 m
east of the road connecting the villages of Tatranská Štrba
and Štrba (see Fig. 4). This locality represents the best exam-
ple of the bryozoan marl facies. Probably, it is a large lensoi-

dal, slump body originated in a similar environment to the
sediments at Hybica. However, abundant large shallow ma-
rine molluscs have been found here. In the upper part of the
section, Nummulites boullei de la Harpe and Operculina al-
pina

Douvillé, have been found. These prove an Eocene age

(Köhler, personal comm, 1995) of these sediments.

The Zuberec Formation represents flysch type sediments.

These are calcareous sandstones interbedded with clay-
stones and rarely with embedded limestones. The Bryozoa
occur as grains within the sandstones.

At Rajecké Teplice (see Fig. 5), bryozoans occur in a

medium-grained calcarenite, exposed above the Bystrička
creek, south of the village.

The bryozoans from Poluvsie (Fig. 6) were found in rocks

collected in the field around the hill called Diel (473.4 m).
The rock is similar to that at Rajecké Teplice, an yellowish to
brownish medium-grained calcarenite.

The depositional environments of these localities cannot

be suggested due to the small amount of remains of bryozo-
ans as well as other fossils.

Morphology

The anascan Bryozoa have a zooecial frontal surface

formed by an uncalcified frontal membrane. Calcified cryp-
tocyst usually lies beneath these membrane, and can be short
(Pseudomalacostega and Cribrimorpha) or extend forward
towards the aperture (Coilostega and Pseudostega). The
space between membrane and cryptocyst forms part of the
hydrostatic system used in tentacle protrusion. The system
used parietal muscles which depress the frontal membrane
and reduce the space between it and the cryptocyst. These
parietal muscles are located in various places, mostly being

The proximal part of the zooecia, not covered by the frontal

membrane, may form a calcified frontal wall called the gym-
nocyst.

Interzooecial avicularia and/or vibracula and ovicells are

generally present.

Systematics

All of the anascan Bryozoa found have been listed in Table

1 with references to their last description. The higher taxa are
listed according to Gordon (1986).

1996a Ramphonotus sp., Zágoršek p. 125, Pl. 2, Fig. 2

Description:

Zoaria encrusting. Zooecia membraniporiform,

oval to triangular, with very short cryptocyst. Opesia triangu-
lar. A shallow, narrow furrow separates neighboring zooecia.
No gymnocyst. Mural rim narrow, same width around all zoo-
ecium, smooth. Vibracula rare, usually situated among three or
four autozooecia, small, tube-like, with circular orifice.
Remarks:

The described specimens are identical in shape of

the zooecia and shape and location of the vibracula with the
holotype deposited in the Natural History Museum in Vien-
na. However the holotype mural rim is slightly ribbed.

Gordon (1984) considered Ramphonotus to be a junior

synonym of Amphiblestrum. Small gymnocyst, development
of the cryptocyst and position of the avicularia characterized
genus Amphiblestrum. Presence of these features in the de-
scribed specimens allow us to list this species under the ge-
nus Amphiblestrum.
Occurrence:

Štrba locality, probably also in the Poluvsie

and the Partizánska upča localities.

restricted to the proximal margin of the orifice or passing in
pairs through openings in the cryptocyst called opesiules.

The frontal membrane is surrounded by an elevated, calcified

margin called the mural rim. In the Cribrimorpha, the membra-
nous frontal is covered by a costal frontal shield (pericyst).

The true opening, where tentacles are protruded is called

the orifice. However, when the membranous frontal wall does
not fossilize, the preserved opening is called the opesium.

EOCENE ANASCAN BRYOZOA FROM NEW LOCALITIES IN THE WESTERN CARPATHIANS, SLOVAKIA 405

Description:

Zoaria free, conical, cupuliform disk in shape.

Preserved are about one third of the whole colony. Rectan-
gular zooecia arranged in radial rows. Orifice oval to circu-
lar. Mural rim narrow. The cryptocyst developed. Ovicell
endozooecial, have not been observed. Avicularia as well as
vibracula present small, oval.
Remarks:

Only a fragment of a zoarium has been found.

However, the shape and morphology of the zooecia allow us
to determine the most probable species, but many of the spe-
cific features have not been preserved (mainly the ovicells).

Description:

Zoaria erect, not articulated. Zooecia drop-like,

narrow, very long with enormously elongated proximal part —
canda. The canda is as long as the rest of zooecium, sometimes
even longer. Orifice terminal, with wide sinus on the proximal
border. No avicularia or ovicells.
Remarks:

The described specimens are identical with holo-

type of Crisidia vindobonensis Reuss 1848 as well as of the
holotype of Unicrisia tenerrima Reuss 1869 deposited in the
Natural History Museum in Vienna. Because Crisidia vindo-
bonensis

Reuss 1848 is the first description of this species it

should be used instead of Chlidoniopsis tenerrima (Reuss).
Braga (pers. comm, 1997) argues, that Reuss (1869) himself
changed the name vindobonensis to tenerrima, because the
species does not occur in the Vienna Basin but in Val di Lon-
te in Italy. However the name of species cannot be changed
even by the author himself (according to Intern. Code of No-

mencl.). So the occurrence of the species is not a reason for
changing the species name, neither is it incorrect.

Description:

Zoarium articulated, with cylindrical segments

(internodes). Zooecia in four longitudinal rows, alternating
with each other. Zooecia drop-like in shape, proximally taper-
ing. Mural rim narrow, smooth. Cryptocyst concave, exten-
sive, smooth. Orifice semilunar with enlarged proximo-lateral
corners for parietal muscles. No avicularia. Ovicell endozooe-
cial, small, have not been observed.
Remarks:

Each zoarium can yield huge numbers of intern-

odes, which is the reason for the large abundance of Cellaria
fragments in the fossil record.

This is a common species at Štrba locality and

is rarely found also at Hybica.

Description:

Zoaria erect unilamellar (cellariiform), with two

rows of zooecia. Zooecia with opesia as long as one half of the
zooecial length. On the proximal margin of opesia, there is a
triangular to oval avicularium with pivotal bar. A small, circu-
lar vibraculum is attached near the distal margin of the opesia.
On the dorsal surface, each zooecium has a vibraculum.
Remarks:

The specimens described by Braga & Barbin

(1988) from Bressana have narrower zoaria and a small fur-
row separating adjacent zooecia on the dorsal surface of the
zoarium. These features are not described by Waters (1891),
however it could be explained by within species variation.

Two specimens found in Štrba have no frontal avicularia.

Scrupocellaria brendolensis

Waters 1891 differs from

Scrupocellaria elliptica

(Reuss 1848) mainly in having avic-

ularia on the frontal surface of the zoarium. However the
avicularia could be missed due to the bad presevation of the
specimens. So these two specimens more probably belong
to Scrupocellaria brendolensis Waters 1891 than to Scrupo-

nar aperture. The width of the zooecium ranges from 0.146
mm to 0.261 mm and length is from 0.232 mm to 0.322 mm.
Frontal wall consists of 6–8 pair of costae with very narrow
lateral costal fusions. Median lamella not developed. Aper-
ture semilunar. Oral spines sometimes missing, sometimes
developed. Avicularium large, intrazooecial, with long ros-
trum, without pivotal bar. Hyperstomial ovicell with smooth

Remarks:

According to David & Pouyet (1974) Cellepora

scripta

Reuss 1848 and Cellepora megacephala Reuss 1848

are junior synonyms of Eschara radiata Moll 1803. However
Schmid (1989) pointed out that Cellepora scripta Reuss

synonym) is a different species — thus named Puellina
(Cribrilaria) scripta

Reuss 1848. Studying the holotype of

Reuss material and reading the description of Cribrilaria ra-
diata

(Moll) by David & Pouyet (1974) I agree with

Schmid’s (1989) opinion and do not list Cellepora scripta

few costae (20 or fewer), no secondary aperture and very
few or no avicularia. The described specimens are coherent
with the genus Anornithopora in forming a median lamella,
the apertural bar and in the absence of avicularia.

The new specimens from Štrba allow a more precise deter-

mination than the specimens from Hybica (Zágoršek 1994).
Occurrence:

Štrba and Hybica localities

Conclusions

Six Eocene localities with Bryozoa have been newly dis-

covered in the Slovak part of the Western Carpathians. A to-
tal of 24 Eocene anascan Bryozoa (see Table 1) are known
from the Slovak part of the Western Carpathians. The richest
bryozoan associations are found at the Hybica and Štrba lo-
calities which have similar lithology. They also have the
most species in common (six).

The environment of the localities is of two different types.

First, shallow marine with Lunulites (and Lacrimula) where
Bryozoa are common (Východná, Partizánska upča localities,
and probably also Rajecké Teplice and Poluvsie localities).

The second, neritic, margin of the shelf influenced by up-

welling, where the bryozoan zoaria are only represented by
allochems in the sediments (Zágoršek 1996).
