Trace fossils of the ichnogenus Zoophycos have been described for the first time from the Silurian of Baltica. They occur in Llandovery pure limestones of middle Estonia and in Ludfordian argillaceous limestones and early Pridoli crinoid grainstones of western Estonia (Saaremaa). The occurrence of Zoophycos in the Silurian of Estonia was not restricted to a particular facies, though all finds come from shallow-water sediments. Zoophycos had a wide geographic distribution in the Silurian.
