The classic Devonian fossil fish site at Tynet Burn, Fochabers, NE Scotland has been investigated following recent excavations. The fish assemblage consists of placoderms, acanthodians, an actinopterygian, porolepiforms, osteolepiforms and a dipnoan. The assemblage is typical of the 'Achanarras Fauna' of Eifelian age which is widespread in the Orcadian basin, representing a time of generally high lake levels. The most diverse fauna occurs in the Upper Nodule Bed which can be divided into top… 
Recognizing the Kačák Event in the Devonian terrestrial environment and its implications for understanding land–sea interactions
Abstract The Kačák Event is a late Eifelian (Mid-Devonian) episode of marine dysoxia/anoxia with associated extinctions. It has been widely recognized in the shelf seas that surrounded the Old Red
First report of fish trace fossils (Undichna) from the Middle Devonian Achanarras Limestone, Caithness Flagstone Group
Two newly discovered specimens of the fish locomotion trace Undichna (U. britannica and Undichna isp.) are described from the Middle Devonian Achanarras Limestone Member (Caithness Flagstone Group,
Fossil Fish Taphonomy and the Contribution of Microfossils in Documenting Devonian Vertebrate History
Of late little work has been done on Palaeozoic fossil fish taphonomy especially in the Devonian period, [known also as the Age of Fishes], apart from the best-known Lagerstatten. Konservat deposits
Palaeoenvironmental reconstruction of the recent history of Lake Chiuta Wetland, south Malawi
Understanding the environmental trajectory over the recent (ca. 200 years) of shallow inland water bodies is key to sustainable management of the fisheries industry that is facing severe challenges.

An investigation of the genus Mesacanthus (Chordata: Acanthodii) from the Orcadian Basin and Midland Valley areas of Northern and Central Scotland using traditional morphometrics
TLDR
Based upon morphological and morphometric comparisons, this investigation has found that at least two species of Mesacanthus are valid (M. mitchelli and M. pusillus) as specimens from the Lower Devonian and Middle Devonian have been shown to differ significantly in a number of important ways.
Discovery of the arthrodire genus Actinolepis (class Placodermi) in the Middle Devonian of Scotland
Synopsis A single specimen of the placoderm Actinolepis found in the Middle Devonian (Eifelian) Achanarras fish bed of Achanarras Quarry, Caithness, is the first record of the genus in the Devonian
Preservation of Devonian chemotrophic filamentous bacteria in calcite veins
Filamentous and possible coccoid bacteria are preserved in calcite vein-fills cutting Devonian lacustrine limestones in the Tynet Burn fish bed near Fochabers, N.E. Scotland. Filamentous bacteria
Unusual preservation of the internal organs of acanthodian and actinopterygian fish in the Middle Devonian of Scotland
Synopsis Relics of internal organs identified as kidney, liver and heart, and also eyes of acanthodian and actinopterygian fishes, have been found in specimens from the Middle Devonian nodule bed
