Abstract
The thelodont Loganellia cuneata (Gross) is redescribed and new thelodont taxa Paralogania perensae sp. nov., Nethertonodus laadjalaensis sp. nov., and Longodus acicularis gen. et sp. nov. are established. The last taxon belongs to the family Longodidae fam. nov. of Thelodonti but its order is uncertain. This assemblage comes from the Tahula Beds of the Kuressaare Stage, Ludlow, Upper Silurian of Estonia.
