A NEW SPECIES OF LACCOGNATHUS (POROLEPIFORM CROSSOPTERYGII) FROM THE DEVONIAN OF LATVIA

Abstract

A new species of the genus Laccognathus, L. grossi sp. nov., from the upper strata of the Gauja Formation of the Main Devonian Field ( Lode locality, Latvia) is established. Morphological similarity and differences of the new species from the previously described L. panderi Gross from the lower strata of the Gauja and the Amata Formation of Latvia are discussed.
