“…It is worth noting that the actual fossiliferous horizon(s) that produced the fish fossils collected in the 1800s is nowadays unknown ( Montenat et al, 2018 ). Numerous additional Maastrichtian localities of are scattered all over the world, but most of these correspond to non-bedded, high-energy deposits, which only yielded disarticulated fossils and are characterized by preferential preservation (e.g., winnowing)—and/or previous collection biases—towards large or robust elements and fossil individuals ( Arambourg, 1952 ; Cappetta, 1972 ; Grande & Chatterjee, 1987 ; Prasad & Sahni, 1987 ; Chalifa & Lewy, 1991 ; Bardet et al, 2000 ; Murray, 2000 ; Alvarado-Ortega et al, 2006 ; Parris, Smith-Grandstaff & Gallagher, 2007 ; Friedman, 2009 ; Bardet et al, 2017 ; Cione et al, 2018 ). Identifiable actinopterygian components of such assemblages are usually dominated by isolated teeth, or dentigerous bones of typical late Mesozoic ray-finned fishes such as †ichthyodectoids or †enchodontoids.…”

“…At the family level and at higher taxonomic levels, the Maastrichtian assemblages from Eurytania are dominated by faunal components, such as elopomorphs and epipelagic aulopiforms, typical of Late Cretaceous marine sites of the Tethys and beyond (Davis, 1887;Arambourg, 1952;Arambourg, 1954;Siegfried, 1954;Goody, 1969;Forey et al, 2003; Figure 9 Map of the Maastrichtian (green dots) and Paleocene (yellow dots) faunas preserving marine actinopterygian fossils in anatomical connection.

The Sawshark Redemption: Current knowledge and future directions for sawsharks (Pristiophoridae)

“…The oldest pristiophorid remains have been found in Cretaceous deposits from Lebanon (Woodward, 1932) and belong to either the extant genus Pristiophorus (Engelbrecht et al., 2017) or the recently revalidated extinct genus Propristiophorus (Cione et al., 2018; Herman & Van Waes, 2014). Previously, all fossil material assigned to Propristiophorus was synonymized with Pristiophorus .…”
