“…T h e ligament of Otapiria has been the subject of m u c h debate, a n d its correct interpretation has significant implications regarding assignment of this genus to the M o n o t i d a e or some aviculopectinoid family-rank taxon. W a t e r h o u s e (1982,2008) agreed with the few previous workers (Ichikawa, 1958;Cox, in Newell et al, 1969;Yin et al, 2004) a n d claimed t h a t the ligament of Otapiria is alvincular a n d considered it as the type genus within the Otapiridae (Order Ostreoida; S u b o r d e r Etheripectinoidina). A re-evaluation of the hinge of Otapiria marshalli ( T r e c h m a n n ) provided below suggests t h a t the genus possesses a feeble single resilifer, as k n o w n from other m o n o t i d s a n d p r e s u m a b l y Lupherella (e.g., G r a n t -M a c k i e , 1978a; Sha a n d Fursich, 1994).…”

“…Discussion.-Although Marwick (1935) originally placed Otapiria within the Pteriidae, Cox (in Newell et al, 1969) and more recently Yin et al (2004) placed the genus within the Aviculopectinidae based on an inferred alvincular ligament. Instead, Otapiria is considered to belong to the Monotidae following Zakharov (1962), Imlay (1967), Zapfe (1973), Damborenea (1987Damborenea ( , 2002, and Ando (1988) despite the argument by Ichikawa (1958) and Waterhouse (2008) that the inferred ligament pit of Otapiria is alvincular and atypical of other monotids.…”

Late Triassic Bivalvia (chiefly Halobiidae and Monotidae) from the Pardonet Formation, Williston Lake area, northeastern British Columbia, Canada

The Upper Triassic of the Williston Lake area of northeastern British Columbia is represented by a nearly continuous series of fossil-rich sediments that were deposited in the Western Canadian Sedimentary Basin in an offshore mid-paleolatitude setting on the western margin of cratonic Pangea. The fossils in this report come primarily from the upper Carnian–upper Norian Pardonet Formation, which has been the subject of numerous paleontologic studies on ammonoids and conodonts, yet has received little attention with regard to its bivalve fauna. Fossil bivalves belonging to the thin-shelled bivalve genera Halobia, Eomonotis, and Monotis dominate the benthic macrofauna and occur within unique shell accumulations that are interpreted to represent oxygen-controlled monospecific paleocommumities that have undergone little post-mortem transportation. Systematic analyses of more than 1,000 individual bivalve specimens resulted in the identification of 25 species-rank taxa, a majority of which belong to the pterioid genus Halobia and the pectinoid genera Eomonotis and Monotis. Of these, four new species are recognized, including 1) upper Carnian Halobia tozeri n. sp. characterized by a unique triangular outline; 2) lowermost Norian Halobia selwyni n. sp. closely related to H. beyrichi and first appearing with H. austriaca which is proposed as a potential datum for the Carnian–Norian boundary; 3) Norian Meleagrinella mclearni n. sp., a new name for previously identified species; and 4) upper Norian Otaparia norica n. sp. which has a delicate thin shell, unique outline, and fine ornament. A revised and refined biochronology of Upper Triassic Bivalvia (chiefly Halobiidae and Monotidae) integrated with conodont and ammonoid zones and standard Triassic stages is presented for the Upper Triassic of the Williston Lake area and permits enhanced correlation to coeval faunas elsewhere in the North American Cordillera, and to the Boreal, Panthalassan and Tethyan faunal realms.

The middle Mesozoic of the southern Junggar Basin is a source of abundant Late Triassic-Jurassic non-marine and Early Jurassic marine–littoral bivalves. The bivalve chronology provides a framework for dating the strata and documents Early Jurassic transgressions and the end-Triassic mass extinction in the Junggar Basin. The first occurrences (FOs) and last occurrences (LOs) of Utschamiella cf. tunguensis and Uts . cf. obrutschevi lay in the basal upper Rhaetian. The FOs of Ferganoconcha sibirica , F . subcentralis , Unio manasensis , U . mirabilis , and Waagenoperna are at, and the FOs of Margaritifera isfarensis , Tutuella rotunda and T . chachlovi adjoin the base of the middle Sinemurian. The LOs of Yananoconcha hengshanensis and Waagenoperna are at the Lower-Middle Jurassic boundary. The LOs of Psilunio , Cuneopsis and F . subcentralis are near the Middle-Upper Jurassic boundary. Non-marine bivalves disappeared in the late Rhaetian, due to a sudden Norian-Rhaetian temperature drop. New forms did not return until the Sinemurian, when the climate warmed. The transgressions created low-relief terrestrial environments, in which organisms including bivalves thrived, leading to the formation of large quantities of coal, oil and gas. The Junggar Basin shifted from Arctic to subtropical latitudes in the Northern Hemisphere between the Early and Middle Jurassic.

The area of the city of Shenzhen at the Pearl River Delta in Guangdong Province, China, comprises rocks that preserve, with few interruptions, around 1.8 billion years of geological history. However, to date, only few scientific studies within a palaeontological context have been conducted on the sediment rocks in Shenzhen. Herein, the fossil record and heritage potential of Shenzhen is reviewed. The few existing previous investigations revealed a rich terrestrial and marine fossil record and show the great potential of this area for future palaeontological research, particularly on the upper Palaeozoic and Mesozoic strata: Carboniferous successions show plant remains and a diverse benthic marine fauna; fossils from Upper Triassic–Middle Jurassic sediment rocks provide important data for terrestrial and marine palaeoecosystems of this time; and the discovery of dinosaur nests in the Upper Cretaceous strata complements the previously known distribution of dinosaurs in South China. Additionally, micropalaeontological and palynological data from the upper Palaeozoic as well as Cenozoic successions in Shenzhen reveal diverse assemblages of foraminifera, ostracods, diatoms, and sporomorphs. Moreover, fossil finds in equivalent rocks in adjacent areas indicate great potential for the units in the Shenzhen area, in which, so far, no fossils have been found.
