Devonian udoteacean green algae from the Cantabrian Mountains (Santa Lucía Formation), NW-Spain.
Resumen
The erect Udoteacean green algae Pseudopalaeoporella lummatonensis (Elliott, 1961) and "Litanaia" graecensis Hubmann, 1990 are described from the Santa Lucía Formation (Lower to Middle Devonian; Upper Emsian to Lower Eifelian) at Geras de Gordón (NW-Spain, Cantabrian Mountains). Investigations of the depositional environment of the sections containing udoteacean thalli indicate a position in a protected subtidal area on a gently inclined ramp. Floristic and biogeographical relations are discussed.
