“…The relative abundance and diversity of fossil aulopiforms can also be correlated with an open, deeper water setting. †Ichthyotringoids, for example, which are the most common teleosts in the Maastrichtian of Eurytania, have been reported from several older localities corresponding to open marine paleoenvironments (such as Jebel Tselfat; ( Arambourg, 1954 ; Khalloufi, Ouarhache & Lelièvre, 2010 ), Hakel, Namura and Sahel Alma, Lebanon ( Davis, 1887 ; Forey et al, 2003 , and references therein), and Sendenhorst ( Dietze, 2009 )). Given their fossil record and their longirostrine anatomy, †ichthyotringids can be envisaged as Cretaceous epipelagic predatory analogs of modern needlefishes ( Froese & Pauly, 2019 ).…”

“…The presence of †Ichthyotringa in the Maastrichtian of Eurytania has been previously indicated by Koch & Nicolaus (1969), who also referred to it in the same text with its junior synonym †Rhinellus. We note that prior to our reassessment of the Eurytanian Maastrichtian fossils, †Ichthyotringidae were widely thought to be restricted to Cenomanian-Campanian deposits, thus, not reaching the K-Pg boundary (Goody, 1969;Dietze, 2009;Davis & Fielitz, 2010;Da Silva & Gallo, 2011;Newbrey & Konishi, 2015). Whereas the †ichthyotringoid †Apateodus was thought to have gone extinct in the early Maastrichtian (Friedman, 2012).…”

The fossil record of marine ray-finned fishes (Actinopterygii) from the time interval surrounding the Cretaceous–Paleogene (K–Pg) extinction is scarce at a global scale, hampering our understanding of the impact, patterns and processes of extinction and recovery in the marine realm, and its role in the evolution of modern marine ichthyofaunas. Recent fieldwork in the K–Pg interval of the Pindos Unit in Eurytania, continental Greece, shed new light on forgotten fossil assemblages and allowed for the collection of a diverse, but fragmentary sample of actinopterygians from both late Maastrichtian and Paleocene rocks. Late Maastrichtian assemblages are dominated by Aulopiformes (†Ichthyotringidae, †Enchodontidae), while †Dercetidae (also Aulopiformes), elopomorphs and additional, unidentified teleosts form minor components. Paleocene fossils include a clupeid, a stomiiform and some unidentified teleost remains. This study expands the poor record of body fossils from this critical time interval, especially for smaller sized taxa, while providing a rare, paleogeographically constrained, qualitative glimpse of open-water Tethyan ecosystems from both before and after the extinction event. Faunal similarities between the Maastrichtian of Eurytania and older Late Cretaceous faunas reveal a higher taxonomic continuum in offshore actinopterygian faunas and ecosystems spanning the entire Late Cretaceous of the Tethys. At the same time, the scarcity of Paleocene findings offers tentative clues for a depauperate state of Tethyan ichthyofaunas in the aftermath of the K–Pg Extinction.

“…Data coverage are summarized in Data S3. REAGENT Node Calibration and Divergence Time Estimation Although over 90 putative myctophiform fossils have been described to date based on both otoliths and body impressions [65,66], none of the extinct lineages have been placed in a phylogenetic context within Myctophiformes [but see 67,68,69]. Therefore, calibrations for internal nodes within the order were derived from a combined genus-level Bayesian morphological and molecular analysis of extant and fossil taxa (see Figure S1; Data S6, S7).…”

Diversification Patterns of Lanternfishes Reveal Multiple Rate Shifts in a Critical Mesopelagic Clade Targeted for Human Exploitation

The mesopelagic (midwater) and deep-sea environments together comprise over 90% of the volume of the world ocean [1] and provide services that are only recently becoming recognized [2]. One of the most significant of these services relates to midwater fish biomass, recently estimated to be two orders of magnitude larger than the current worldwide fisheries catch [3, 4]. Calls to exploit midwater fish biomass have increased despite warnings about the unknown recovery potential of such organisms [2] and despite existing data suggesting that deep-sea fishes could be classified as endangered [5]. Here, to provide a null model for the respondability of midwater fishes, I use lanternfishes-which comprise the majority of worldwide midwater fish biomass [6]-to examine the diversification response of a critical midwater clade to oceanic changes over evolutionary timescales, including several extinction and turnover events. Using a time-calibrated molecular phylogeny based on seven autosomal protein-coding loci, with over 50% species sampling and three ingroup node calibrations, I show that lanternfishes exhibit a continuously increasing diversification rate, consistent with nonequilibrium speciation dynamics, and three major evolutionary rate shift locations with timing that is similar to those of marine clades in more well-known environments. These results suggest that lanternfish diversification patterns overlapped with major events in the physical partitioning of the ocean volume and that the clade has responded positively to a range of pre-Anthropocene extinction drivers [7]. However, lanternfish respondability to modern extinction drivers-habitat loss and overexploitation-is best addressed with populational and ecological data and remains largely unknown.

“…Differences with the latter taxon can be found in the markedly convex (vs. straight) posterior margin of the quadrate, and possibly in the presence of a wider dorsal articulation surface of the hyomandibula in the Gavdian specimen. The Gavdian specimen bears a horizontal crest or strengthening bar on the opercle, which is absent in the better preserved † Sardinioides monasteri from the Campanian of Westphalia, Germany ([ 61 , 78 , 96 ]; T.A. pers.…”

The global body-fossil record of marine ‘fishes’ from the time interval immediately preceding the Cretaceous–Paleogene Extinction is markedly poor. This deficiency appears to be further exacerbated with regards to offshore and deep-water taxa, obscuring our understanding of the state and composition of corresponding vertebrate faunas at the onset of this major extinction event. Recent fieldwork in the mid–late Maastrichtian exposures of the Pindos Unit in Gavdos Island, Greece, yielded a small but informative sample of fossil ‘fishes’, which inhabited the Tethys approximately three to four million years before the extinction. In this work we describe this sample, which comprises between eight and nine discrete morphotypes of various size classes, belonging to †Ichthyodectoidei, Aulopiformes (†Dercetidae, †Enchodontidae, †Ichthyotringidae), cf. †Sardinioididae, as well as the hexanchid shark †Gladioserratus sp. The new material expands the faunal list for the Maastrichtian of Gavdos Island, and the Pindos Unit as a whole, and further allows for the description of a new genus and species of †Enchodontidae and a new species of †Ichthyotringidae. The two new taxa are found to be widespread in the Maastrichtian of the Pindos Unit. The overall character of the assemblage agrees with previous interpretations of an offshore and rather deep depositional environment for the fossiliferous horizons. Furthermore, it exhibits a higher diversity than, and little taxonomic overlap with penecontemporaneous teleost assemblages from the Tethys, and informs on the otherwise poorly known Maastrichtian offshore and deep-water marine ichthyofaunas of the region.
