Vol. 182 (1999): Vertebrate remains from Upper Silurian – Lower Devonian beds of Hall Land, North Greenland

Cover photo: Transitional scale of Thulolepis striaspina gen. et sp. nov., a new small thelodont species from the lowermost Devonian of North Greenland. SEM photograph of the holotype, MGUH VP 3510, found in an acetic acid residue of GGU sample 319264. The sample is from a limestone bed in the Chester Bjerg Formation at the top of Monument, an inselberg-like hill in central Hall Land.

The microscopic remains of Palaeozoic vertebrates, such as teeth, scales and small fragments of jaws. spines and bones, have been shown to be a good complement to the less abundant articulated fossil vertebrates. These 'microvertebrates' increase the knowledge of early vertebrate evolution and are also very useful for dating geological strata. This bulletin gives an extended description of small remains of jawless and jawed fish from the Upper Silurian and Lower Devonian of Hall Land, western North Greenland. The biostratigraphic utility of these remains provides data for discussion of the regional stratigraphy and global correlation.
