the nature conservation laws of Estonia. This proposal was not realized but the descriptions of objects were used in the Estonian Primeval Nature Book. She compiled identification cards for more than 40 Saaremaa cliffs and outcrops important for the Silurian palaeontology and stratigraphy, representing type sections of certain stratigraphic units and sites of special fossils. The descriptions of the bedrock objects (cliffs, outcrops) of the Primeval Nature Book have been entered in the Estonian Nature Information System (EELIS).

pleuronectiforms. Later, however, they focused on a comparative study of fish teeth and gill-rakers, which have very different morphologies in different taxa and are valuable in characterizing species but could also be used in establishing new ones. Märss has started similar research also on clupeiforms. With such work she laid the foundation of microichthyological studies in Estonia.

In addition to fossil distribution in the Silurian and Lower Devonian, the carbon isotope curves of geological sections of these islands were compared with those of the Baltic and the Central Ural ones, similar curve patterns were found, and these distant sections were correlated. 539:. Her interest in fossil vertebrates arose and deepened through the geology projects of undergraduate students (1967, 1969), graduation (diploma) work (1970) at Tartu State University and in studies for the Candidate of Sciences thesis (PhD) in the Institute of Geology (1983).

Märss has devoted great attention to the use of agnathans and fish scales in the subdivision and correlation of sedimentary rocks of the Silurian sea basins. As the author of the Regional Vertebrate Biozonal Scheme , she initiated the creation of the Global Silurian Vertebrate Biozonal Scheme , which

in the Palaeobaltic Sea, she used the material from Himmiste-Kuigu quarry collected by A. Luha in 1929. Together with lithologists, she found out that a shoal of thelodonts died in a shallow depression on the bottom of the lagoon behind the reef belt towards the land; the depression acted as a trap
