“…Therefore, there is some confusion in the literature about the assignment of Mesozoic species to Palaeoneilo or Mesosaccella . Cox (1937) and Cox et al (1969) stated that Palaeoneilo ranged from the Ordovician to the end of the Mesozoic and that there is no reason to separate the Paleozoic and Mesozoic species in different genera—a view that is not followed here. In fact, the distinction between the two genera is very difficult, especially because the type species of Palaeoneilo ( Nuculites constricta Conrad, 1842, p. 249) from Middle Devonian strata of New York State is poorly known.…”

“…In fact, the distinction between the two genera is very difficult, especially because the type species of Palaeoneilo ( Nuculites constricta Conrad, 1842, p. 249) from Middle Devonian strata of New York State is poorly known. According to Cox et al (1969, p. N237) and Sha and Fürsich (1994, p. 40), the presence of a faint depression between anterior and posterior teeth below umbo, foreshadowing a resilifer, is typical of Mesosaccella . However, Carter (1990) observed a very small resilifer in the right valve of Palaeoneilo elliptica (Goldfuss, 1837) from the Lower Jurassic of Germany.…”

“…According to Ros et al (2014, p. 20), there is no consensus about the family affiliation of the genus Dacryomya . It was assigned to Nuculanidae (e.g., Cox et al, 1969; Hayami, 1975), Nuculidae (e.g., Hodges, 2000; Karapunar et al ., 2020) or to Polidevciidae (Carter, 1990; Jaitly et al, 1995; Delvene, 2001). The Ordovician–Upper Jurassic subfamily Polidevciinae was erected by Kumpera et al (1960, p. 33–34) during their revision of the Nuculanidae from the Ostrava-Karviná District based on a strong posterior umbonal ridge, a short rostrum, and an internal ligament.…”

“…Rollieria was regarded as a subgenus of Nuculana by some workers (e.g., Cox et al, 1969, p. N237; Liu, 1995). Hodges (2000, p. 35) placed Rollieria as a separate genus within the subfamily Yoldiinae (family Yoldiidae) on the basis of a sub-central, slightly prosogyrate umbo, a shallow pallial sinus, an elongated valve, and the lack of an escutcheon and lunule.…”

Revision of Jurassic Protobranch Bivalves from Gebel Maghara, northern Sinai, Egypt

The Jurassic rocks of Gebel Maghara, northern Sinai, Egypt, contain a well-preserved and highly diverse macrobenthic fauna, dominated by bivalves. This fauna, particularly bivalves and gastropods, have received little attention in the last 100 years. In an attempt to provide a sound database on the marine bivalve diversity of Egypt during the Jurassic period, a first faunal group, the protobranch bivalves, is reviewed in detail. Sixteen taxa (three of them new), belonging to two orders, five families, and nine genera are systematically described and compared to closely related Jurassic taxa from various locations, particularly in Europe and India. New species are Nuculoma douvillei n. sp., N. sinaiensis n. sp., and Palaeoneilo aegyptiaca n. sp. In addition, Palaeonucula cuneiformis (J. de C. Sowerby), P. muensteri (Goldfuss), Dacryomya diana (d'Orbigny), D. lacryma (J. de. C. Sowerby), and Praesaccella juriana Cox are identified from Jurassic strata of Egypt for the first time. The younger records of the genus Palaeoneilo have not been accepted by some researchers, since almost all exhibit only limited features. The genus occurs with certainty in the Middle Jurassic (Bajocian‒Bathonian) rocks of Egypt, based on well-preserved external and internal characters. Similarly, Dacryomya and Ryderia from Bathonian‒Kimmeridgian rocks of Egypt are younger than previously recorded from other parts of the world. The identified genera have wide geographic ranges and have been reported from different faunal provinces, which suggests that latitudinal climate differences did not influence their distribution pattern to a great extent.UUID: https://zoobank.org/7f3a9185-d690-4563-bdc0-df1c8d42ec0d

“…The systematics broadly follows the "Treatise on Invertebrate Paleontology" (Cox et al, 1969), although with modifications (Parodiz, 1969;Graf andCummings, 2006, 2007). The synonymy lists include only references to illustrated material or references to material seen by us.…”
