PALAEOECOLOGY OF THE COUNTY 
FERMANAGH BRYOZOAN FAUNA 
The silicified Viséan fauna found towards the top of the Glencar 
Limestone has proved to be very diverse. It has been the subject of a 
number of research papers: the bryozoan element of the fauna has 
been systematically described by Bancroft & Wyse Jackson (1995), 
Olaloye (1974), Tavener-Smith (1965a, 1965b, 1971, 1973), Wyse 
Jackson (1988) and Wyse Jackson & Bancroft (1995a); the 
brachiopods by Brunton (1966a, 1966b, 1968, 1984); and the sponges 
by Reid (1970). These workers have recorded a large number of taxa 
(Tables 32 and 33). Other palaeontological work includes that of 
Gardiner & Mason (1974) who reported the occurrence of 
palaeoniscid fish from strata just overlying the Glencar Limestone, 
at a nearby locality west of Carrick Lough. 
The fauna in County Fermanagh is essentially a bryozoan- 
brachiopod assemblage with rare taxa of other groups, such as 
trilobites, gastropods, bivalves, sponges and corals. This community 
is similar to that developed on the slopes of Asbian reefs of the 
Cracoe area, Yorkshire (Mundy 1978). Brunton (1987) tabulated the 
diverse and abundant fauna from Carrick Lough and Sillees River 
(Table 33). The number of bryozoan species described has been 
increased in this paper, and Bryozoa are now the largest element 
(numerically by species) in the community. The bryozoan fauna is 
dominated by fenestrates, which in turn are dominated by fenestellids. 
However, the delicate cryptostomes are also quite common (Table 
32). 
During this study one blastoid species and one ostracod species 
not recorded by Brunton (1987) have been found. Three specimens 
of the blastoid Monoschizoblastus rofei (TCD.9605), common in 
Asbian strata (Waters & Sevastopulo 1984a, 1984b), and one speci- 
men of the ostracod Polytylites (TCD.9606) complete with both left 
and right valves were found.
