| Abstract | Summary For the past 168 years, the Late Devonian Miguasha biota from eastern Canada has yielded a diversified aquatic component including 20 species of lower vertebrates (anaspids, osteostracans, placoderms, acanthodians, actinopterygians and sarcopterygians) and a poorly diversified invertebrate assemblage as well as a continental component including plants, scorpions and millipedes. Originally interpreted as a freshwater lacustrine environment, recent paleontological, taphonomic, sedimentological and geochemical evidences corroborate a brackish estuarine setting. More than 18,000 fossil fish have been discovered showing various states of preservation including three-dimensional and soft-tissues preservation. Most vertebrates are known from numerous, complete, articulated specimens. Exceptionally wellpreserved larval and juvenile specimens have been identified for 14 out of the 20 species of fishes allowing growth studies and interpretation of different developmental mechanisms. Numerous horizons within the Escuminac Formation are interpreted as either Konservat or Konzentrat Fossil-Lagerstatten. |
