Upper Eocene (Priabonian) Bryozoa from the Waschberg Zone (Austria) are described. Localities at
Reingruberhöhe and Haselbach yielded 153 species by a new method of dissolving bryozoan marl in concentrated
acetic acid. Among them, twelve are new: Tayloripora ovicellata sp.n., Idmidronea uniporica sp.n., Trochiliopora
planiformis sp.n., Aviculiera austriensis sp.n., Otiochmella discoida sp.n., Steginoporella reingruberhohensis sp. n.,
Babickella janensis sp.n., Gordoniella longituda sp. n., Costatimorpha algella sp.n., Adeonellopsis triporica sp.n.,
Chlidoniopsis vavrai sp.n. and Batopora haselbachensis sp.n. All species are described and documented by SEM
photos.
The fauna originally probably lived in a shallow environment and has been redeposited in more deepwater
sequences. The bryozoan assemblage is very similar to those from Hungary (Transdanubian Central Ridge) and
Austria (Molasse Zone), but also similar to those from Romania, Slovakia and Italy.
