Acta Palaeontologica Polonica 24 (1), 1979: 51-64

Genus Thamnoseris differs from the Jurassic representatives of Fungiastraea Alloiteau, 1957, in having extratentacular-intercalicular gemmation instead of intratentacular or extratentacular-marginal gemmation, and in Its trend towards synapticulotheca formation; there seem to be differences in microstructure and/or histology between the two genera. Thamnoseris differs from Kobyastraea Ronlewicz, 1970, in its porous septa, papillar columella, and vesicular endotheca. Three species of Thamnoseris of the Oxfordian/Kimmeridgian are described from the Holy Cross Mts. Poland: Th. cf. frotei Etallon, Th. cf. blauensis Koby and Thamnoseris sp.

Key words: Scleractinia, taxonomy, homeomorphy, Upper Jurassic, Poland.
