The ol<strong>de</strong>st heliolitids (Coccoserididae) of early Katian age from Estonia are an<strong>al</strong>ysed. Only two species<br />
appeared in the Oandu Stage. One species is found in the reef facies of the Vas<strong>al</strong>emma Formation and the<br />
other is collected from the marls of the Hirmuse Formation. The first species grew wi<strong>de</strong> on the sediment<br />
surface and it formed tabular cor<strong>al</strong>la with irregular shapes. The second species encrusted brachiopods,<br />
gastropods and it formed sm<strong>al</strong>l dom<strong>al</strong> and bulbous cor<strong>al</strong>la. Their affinities with Coccoseris ungerni<br />
EICHWALD and Protaraea richmon<strong>de</strong>nsis FOERSTE are discussed.<br />
