Abstract
Thelodont scales are recorded from samples of Silurian limestone from Hall Land, Washington Land and Peary Land, North Greenland. Faunas of probable Early Silurian age compare best with faunas from western Europe, while a fauna of Late Silurian (Pridoli) age from Hall Land can be compared with faunas from Arctic Canada and Tuva. The preoccupied names Logania Gross, 1967 and Katoporus Gross, 1967 are replaced by Loganella and Katoporodus, respectively.
Highlights
The1odont scales are recorded from samples of Silurian limestone from Hall Land, Washington Land and Peary Land, North Greenland
Vertebrate remains are rare in the Lower Palaeozoic of Greenland
Undoubted vertebrates are first known from the Lower Silurian of western North Greenland where Norford (1972) reported anaspid fragments from western Hall Land
Summary
The1odont scales are recorded from samples of Silurian limestone from Hall Land, Washington Land and Peary Land, North Greenland. In 1974 Bendix-Almgreen & Peel recorded abundant vertebrate remains in latest Silurian or possibly earliest Devonian strata in western Hall Land. Examples of the fauna were illustrated by Bendix-Almgreen (1976) in his summary of palaeovertebrate faunas from Greenland He referred thelodont scales to Thelodus trilobatus and Logania spp., cf kummerowi and L. scotica. Thelodont remains are recorded from older Silurian strata at two other 10calities in Hall Land, and from one locality each in Washington Land and Peary Land Scale colour varies from dark brown and black to light grey
