Abstract:The paper presents a short biography and an annotated bibliography of the well-known Soviet palaeoichthyologist and evolutionary morphologist Leonid S. Glickman (1929–2000). His bibliography consists of 46 titles, including 2 monographs, 3 book chapters, 33 research papers, 4 popular papers, and 4 unpublished research reports and dissertations, devoted mainly to Cretaceous and Cenozoic elasmobranchs (principally Lamniformes). The publications cover a period of time between the years 1952 and 1998.
“…Late Cretaceous, probably using this epicontinental seaway to migrate along the peripheral areas of the Neo-Tethys Ocean (e.g., Asian peri-Tethys) and to access the northwestern margin of the paleo-Pacific Ocean. Ptychodus was reported from the Turonian-Santonian of western Kazakhstan by Glickman et al (1970) and Zhelezko and Glikman (1971; see also Popov, 2016), and the Cenomanian-Turonian to ?Campanian of Japan by Goto et al (1996). In the Santonian, the Anglo-Paris basin, the Adria platform, and the southern Central Polish basin certainly were part of the epicontinental areas inhabited by Ptychodus (see Fig.…”

“…Based on ammonites, the layer is dated as early-middle Cenomanian (Nikitin, 1888;Olferev and Alekseev, 2005). Ptychodus teeth are rare in all the above-mentioned fossil sites and coexist with much more abundant assemblages of teeth belonging to various other elasmobranch groups (compare Glickman, 1953;Olferev and Alekseev, 2005;Starodubtseva et al, 2008;Popov, 2016).…”
Isolated teeth belonging to the genus Ptychodus Agassiz, 1834 (Chondrichthyes; Elasmobranchii) from the Upper Cretaceous of the Ryazan and Moscow Oblast regions (European Russia) are described and discussed in detail herein. The taxonomic composition of the Ptychodus assemblage from the Ryazan region is very diverse including the first records of the cuspidate species P. altior and P. anonymus, which thus is largely consistent with those from other contemporaneous European localities. Ptychodus ubiquitously inhabited epicontinental seas of Europe during most of the Cretaceous with the most diverse assemblages coming from southern England, northern Italy, Belgium, and European Russia. Additionally, the material documented here from the Cenomanian of Varavinsky ravine area (Moscow Oblast) represents the northernmost occurrence of Ptychodus hitherto reported from Europe. It is evident that the Late Cretaceous shallow seas of the Russian platform represented a crucial pathway for the dispersal of Ptychodus from the European peri-Tethys to the eastern margins of the Neo-Tethyan Ocean. The Albian-Campanian records of Ptychodus from Europe indicate that its dominance in the peri-Tethys persisted for most of its evolutionary history. A local temperature drop across most of the European shallow seas probably contributed to the narrowing of its geographic range in the peri-Tethyan seas towards the end of the Mesozoic Era. The fossil remains of Ptychodus documented herein are accordingly of utmost importance for better understanding the taxonomic composition of Russian fossil ichthyofaunas and also inform about the dispersal of Ptychodus towards western and eastern peri-Tethyan seas during the Late Cretaceous.

“…Although vomerine tooth plates are part of our chimaeroid sample, only palatine and mandibular plates could be confidently identified generically. Ischyodus palatine plates are easily distinguished from those of Edaphodon, which has been reported from the Saratov Region (Averianov & Glickman 1994;Popov 2016), by having four tritors instead of three, with the fourth tritor being expressed as numerous circular pads or an elongated structure along the labial margin of the plate (Case 1978a;Cicimurri & Ebersole 2014). Ischyodus mandibular plates are labiolingually thinner and the anterior beak is generally shorter compared to Edaphodon mandibulars.…”

“…Fossils of the bony fish Pycnodus sp. were reported by several authors from deposits of the same age in the Volga region (Glickman 1953;Nesov & Averianov 1996;Popov 2016). Glickman (1953), Nesov & Averianov (1996), and Popov (2016) reported approximately 400 Ischyodus and Edaphodon (Callorhinchidae) tooth plates from the Saratov Oblast, and Averianov & Glickman (1994) subsequently described several chimaeroid taxa from Turonian to Santonian deposits near Saratov city.…”

A diverse fish paleofauna occurs in the upper Campanian portion of the Rybushka Formation exposed near Saratov city in the Saratov Oblast, Russia. Twenty taxa have been identified, including two holocephalans (Ischyodus bifurcatus and Amylodon karamysh), twelve elasmobranchs (Synechodus sp., Cederstroemia sp., Cretalamna cf. C. borealis, C. cf. C. sarcoportheta, Archaeolamna kopingensis, Eostriatolamia segedini, E. venusta, Pseudocorax laevis, Squalicorax kaupi, Squalicorax morphotype 1, Squalidae indet., and Squatirhina sp.), and six teleosts (Pachyrhizodus sp., Saurocephalus lanciformis, Paralbula casei, Enchodus cf. E. dirus, E. cf. E. gladiolus, and E. petrosus). Many of these taxa are new to the Campanian fish record of Russia, and the assemblage demonstrates that there is significant taxonomic overlap between the Rybushka Formation paleofauna and that of North America.
