“…This discovery is also significant because it expands the diversity of the middle-late Eocene Ilam fauna. Modern lophotids are found in mesopelagic environments (Olney, 2002), so the presence of at least two representatives of the family in the fauna that is mostly composed by relatives of modern deep-sea teleosts (Arambourg, 1967; Afsari et al, 2014; Přikryl, Brzobohatý & Gregorová, 2016) reinforces its potential as a valuable glimpse of the otherwise poorly known early Cenozoic deep-water ecosystems.…”

Lophotidae, or crestfishes, is a family of rare deep-sea teleosts characterised by an enlarged horn-like crest on the forehead. They are poorly represented in the fossil record, by only three described taxa. One specimen attributed to Lophotidae has been described from the pelagic fauna of the middle-late Eocene Zagros Basin, Iran. Originally considered as a specimen of the fossil lophotid †Protolophotus, it is proposed hereby as a new genus and species †Babelichthys olneyi, gen. et sp. nov., differs from the other fossil lophotids by its relatively long and strongly projecting crest, suggesting a close relationship with the modern unicorn crestfish, Eumecichthys. This new taxon increases the diversity of the deep-sea teleost fauna to which it belongs, improving our understanding of the taxonomic composition of the early Cenozoic mesopelagic ecosystems.

“…The species is herein identified as Bregmaceros filamentosus (Priem, 1908) and ranges from the Middle Eocene to Early Oligocene (P10a-P21a, see BouDagher-Fadel, 2015). It has been reported from the Mediterranean region and its surrounding areas including Georgia (Middle to Late Eocene) and Iran (Middle Eocene to Early Oligocene) (Afsari et al 2014, Kotlarczyk et al, 2006Přikryl et al, 2016).…”

“…The small fish deposits of the high energy bed (layer RML5) belong to the Bregmacerotidae family and are represented by the single genus Bregmaceros. They are small-sized pelagic 1-2cms cod-like fish (Gadiformes) and their age range is from the Eocene to the Holocene (Přikryl et al, 2016). The species is herein identified as Bregmaceros filamentosus (Priem, 1908) and ranges from the Middle Eocene to Early Oligocene (P10a-P21a, see BouDagher-Fadel, 2015).…”

The biostratigraphy and sedimentology of the outcrops and bedrock exposed in archaeological excavations around the harbour area of Beirut (~5 km 2 ) unlock the geological and structural history of that area, which in turn are key to understanding the hydrocarbon and hydrogeological potential of the region. A key location (Site 2) of a studied outcrop section and newly uncovered bedrock is on the northern foothill cliff of East Beirut (Achrafieh). The outcrop section of carbonates is of Eocene beds overlain by conformable Miocene beds. The excavation of the slope bordering the outcrop uncovers a bedrock section of an early Pliocene shoreline of carbonate/siliciclastic sands at its base and a beach-rock structure at top. The age of the shoreline section is dated by an assemblage of planktonic foraminifera including Sphaeroidinellopsis subdehiscens , Sphaeroidinella dehiscens , and Orbulina universa. The Eocene carbonates of Site 2 extend the coverage of the previously reported Eocene outcrops in the harbour area. They form a parasequence of thin bedded chalky white limestones that includes the youngest fossil fish deposits in Lebanon ( Bregmaceros filamentosus ). The deposits are dated as early Priabonian by their association with the planktonic foraminiferal assemblage of Porticulasphaera tropicalis , Globigerinatheka barri , Dentoglobigerina venezuelana, Globigerina praebulloides , Turborotalia centralis and Borelis sp. The Middle Miocene carbonates that conformably overlie the early Priabonian parasequence, include a planktonic foraminiferal assemblage of Globigerinoides trilobus, Orbulina universa and Borelis melo. Elsewhere, in the harbour area, the preserved Eocene limestones are equally directly overlain by conformable Miocene carbonate parasequences of the Langhian - Serravallian age. Younger argillaceous limestone beds of the Mio/Pliocene age occur in the eastern central part of the harbour area and enclose an assemblage of Truncorotalia crassaformis , Globorotalia inflata , and Orbulina universa . The three markers of old and recently raised structural blocks in the harbour area are a Lutetian/Bartonian marine terrace in the south west corner, a lower Pliocene shoreline carbonate section in the north east side and a Holocene raised beach of marine conglomerates in the north east corner of the area. The locations of these paleo-shorelines, less than 2 kms apart, indicate a progressive platform narrowing of North Beirut since the Paleogene. This study underpins the geological complexity of the region and contributes to understanding the underlying geology which will be needed for future archaeological, hydrocarbon and hydrogeological exploration.

“…They are small-sized, pelagic, 1-2 cm codlike fish (Gadiformes), and their age range is from the Eocene to the holocene [12]. The species is herein identified as B. filamentosus (Priem, 1908), and ranges from the Middle Eocene to Early Oligocene (PZ P10a-P21a, see [7], and has been reported from the Mediterranean region and its surrounding areas including Georgia (Middle to Late Eocene) and Iran (Middle Eocene to Early Oligocene) [12][13][14]. The bed thicknesses and sedimentology of the Eocene sections of site 1 and site 2 indicate a decrease in the accommodation space for carbonates from north to south, and from the late Lutetian to the early Priabonian.…”
