“…Elemental and ionic barriers are an obvious prerequisite of a highly osmoregulated organism such as a fish, but the pathway into the otolith is even more regulated than is the case for other tissues. For example, calcified tissues such as bone (Ishikawa et al 1991, Schmitz et al 1991, Miller et al 1992) and scale (Johnson 1989, Pender & Griffin 1996 contain higher concentrations of most elements than do otoliths (Sr is a conspicuous exception), while uncalcified structures such as the eye lens are often characterized by a different suite of elements altogether (Dove & Kingsford 1998). This high degree of regulation is most evident in a phylogenetic comparison, in which the aragonitic skeleton of the most primitive animals (e.g.…”

“…Detection of the finescale salinity differences evident in coralline Sr:Ca ratios (de Villiers et al 1994) are likely to be more difficult in otoliths given the other factors that are known to influence Sr:Ca deposition in otoliths. Strontium isotope ratios have been used to reconstruct salinity history in fish bones and other taxa (Schmitz et al 1991, Holmden et al 1997), but have not yet been tested for this purpose in otoliths.…”

ABSTRACT:The fish otolith (earstone) has long been known as a timekeeper, but interest in its use as a metabolically inert environmental recorder has accelerated in recent years. In part due to technological advances, applications such as stock identification, determination of rnigralon pathways, reconstruction of temperature and salinity history, age validation, detection of anadromy, use as a natural tag and chemical mass marking have been developed, some of which are difficult or impossible to implement using alternative techniques. Microsamphg and the latest advances in beam-based probes allow many elemental assays to be coupled with daily or annual growth increments, thus providing a detailed chronologcal record of the environment. However, few workers have critically assessed the assumptions upon which the environmental reconstructions are based, or considered the possibility that elemental incorporation into the otolith may proceed differently than that into other calcified structures. This paper reviews current applications and their assumptions and suggests future directions. Particular attention is given to the premises that the elemental and isotopic composition of the otolith reflects that of the environment, and the effect of physiological filters on the resulting composition. The roles of temperature, elemental uptake into the fish and the process of otolith crystahzation are also assessed. Drawing upon recent advances i n geochemistry and paleoclirnate research as points of contrast, it appears that not all applications of otolith chemistry are firmly based, although others are destined to become powerful and perhaps routine tools for the mainstream fish biologst.

“…In addition, faunal comparisons do not justify their use as freshwater indicators (Schultze & Cloutier 1996). To the contrary, Bothriolepis canadensis, earlier considered to be a freshwater inhabitant, is now thought to have been marine based on Srg7/Srg6 isotope studies (Schmitz et al 1991). The marine occurrence of B. canadensis is supported for the Frasnian locality of Miguasha, where it co-occurs with marine indicators (acritarchs, Cloutier et al 1997, andtrace fossils, Maples 1996).…”

The fish fauna of Upper Devonian deposits of SW Colorado is described and compared with those of Central Colorado. The osteolepidid Litoptychus is redescribed including skull roof, cheek, palatoquadrate, cleithrum and postcranial elements. A second osteolepidid with cosmine-covered scales and bones is recognized in the Upper Devonian deposits of Colorado. A skull roof and a parasphenoid formerly attributed to Litoptychus, and a pterygoid, cleithrum, ribs and scales are assigned to dipnoans, partly to long-snouted dipnoans cf.

“…An estuarine interpretation best accommodates the different lines of evidence provided by the fauna , the palynofacies , the trace fossil assemblage (Maples 1996), the sedimentological and stratigraphic setting of the formation (Hesse and Sawh 1992;, and the geochemistry of the sedimentary rocks and bones (Schmitz et al 1991;Vézina 1991;El Albani et al 2002;Matton et al 2012).…”

Over the past 170 years, the Late Devonian Miguasha biota from eastern Canada has yielded a diverse aquatic assemblage including 20 species of lower vertebrates (anaspids, osteostracans, placoderms, acanthodians, actinopterygians and sarcopterygians), a more limited invertebrate assemblage, and a continental component including plants, scorpions and millipedes. Originally interpreted as a freshwater lacustrine environment, recent paleontological, taphonomic, sedimentological and geochemical evidence corroborates a brackish estuarine setting. Over 18,000 fish specimens have been recovered showing various modes of fossilization, including uncompressed material and soft-tissue preservation. Most vertebrates are known from numerous, complete, articulated specimens. Exceptionally well-preserved larval and juvenile specimens have been identified for 14 out of the 20 species of fishes, allowing growth studies. Numerous horizons within the Escuminac Formation are now interpreted as either Konservat– or Konzentrat–Lagerstätten.SOMMAIREAu cours des 170 dernières années, le biote du Dévonien supérieur de Miguasha de l’Est du Canada a fourni un assemblage aquatique diversifié, comprenant 20 espèces de vertébrés inférieurs (anaspides, ostéostracés, placodermes, acanthodiens, actinoptérygiens et sarcoptérygiens) et un assemblage peu diversifié d’invertébrés ainsi qu’une composante continentale, représentée par des plantes, des scorpions et des mille-pattes. À l’origine interprété comme un milieu lacustre d’eau douce, les dernières preuves paléontologiques, taphonomiques, sédimentologiques et géochimiques confirment un environnement saumâtre rappelant celui d’un estuaire. Plus de 18,000 fossiles de poissons ont été découverts montrant différents états de conservation, notamment en trois dimensions et la préservation de tissus mous. La plupart des vertébrés sont connus par de nombreux spécimens complets et articulés. Des spécimens de larves et de juvéniles, exceptionnellement bien conservés, ont été identifiées pour 14 des 20 espèces de poissons permettant des études détaillées de leur croissance. De nombreux horizons au sein de la Formation d’Escuminac sont interprétés soit comme des Konservat– ou Konzentrat–Lagerstätten.
