“…Third veins unseen. Comparison and discussion The present specimens are similar in gross morphology of lamina and venations to those of N. extenuinervis originally described from the North America (Upchurch et al, 1994), and of N. tenuinervis (Fortaine) Berry from Israel (Dobruskina, 1997), differing in having less primary veins and primaries forking near the leaf margins. N. virginiensis Fontaine (1 889) differs from present material in having an undulate or obscurely crenulate margin and possibly a strongly cordate leaf base.…”

Three taxa of Late Cretaceous aquatic angiosperms, Queruexia angulata (Lesq.) Krysht, Cobbania corrugata (Lesq.) Stockey et al. and Nelumbites cf. extenuinervis Upchurch et al. from Jiayin of Heilongjiang, NE China, are described in detail. Among them, Cobbania and Nelumbites from the Upper Cretaceous in China are reported for the first time. The aquatic angiosperm assemblage of Queruexia‐Cobbania‐Nelumbites appears to imply a seasonal, warm and moist environment in the Jiayin area during the Santonian‐Campanian time.

“…As in Sinai, the Middle Turonian relative sea‐level fall (post‐Tu1 LST of Buchbinder et al ., 2000) is documented by omission and erosion surfaces (Lewy & Avni, 1988). Freshwater lakes covered the platform as indicated by claystones that contain an angiosperm flora (Dobruskina, 1997). Furthermore, a siliciclastic–evaporite facies (‘clastic unit’) occurs in the Negev and further north with palaeosols, pedogenic alterations and fluvial sandstones.…”

Relative sea-level changes on the mixed carbonate-siliciclastic platform of Sinai are manifested in shifts of distinct facies belts (deep-water facies, highenergy subtidal, shallow subtidal, lagoon, shallow shoreface siliciclastics, supratidal) and are interpreted in terms of sequence stratigraphy. Eight sedimentary sequences are recognized for the Upper Cenomanian to Santonian. Their correlation along a north-south transect reveals distinct changes in lithofacies and progradation/retrogradation patterns within the individual systems tracts. The number and stratigraphy of the sequence boundaries of Sinai correlate well with those from adjacent areas. Patterns of increased subsidence are documented for the Central Sinai Basin since the Late Cenomanian by increased thickness of the stratal packages (post-CeSin 7 HST, post-TuSin 1 LST and HST, post-TuSin 2 LST) and are balanced by varying accumulation rates. Based on new sedimentological and biostratigraphic data, large-scale palaeogeographic maps and cross-sections show the: (1) temporal and spatial evolution of the Central Sinai Basin, e.g. its latest Cenomanian initial formation, Lower Turonian deep-water facies, Middle Turonian to Coniacian synsedimentary subsidence; (2) drowning of the Cenomanian platform coinciding with the latest Cenomanian to Early Turonian relative sea-level rise; (3) re-establishment of the platform in Middle-Late Turonian times; and (4) a Coniacian basin and swell morphology.

“…"Nymphaea " mesozoica is the Cretaceous fossil that is most similar to Jaguariba. However, the leaves differ from Jaguariba by their shape, being wider than long and usually larger despite some overlap in size (Dobruskina, 1997). Unfortunately, the description is rather short and the illustrations do not allow further comparison.…”

Morphology and anatomy of a fossil nymphaealean plant, Jaguariba wiersemana gen. nov. et sp. nov. from the late Early Cretaceous of northeastern Brazil, and extant aquatic flowering plants are comparatively studied. Characteristic features indicate that Jaguariba gen. nov. is a member of Nymphaeaceae, and may belong to Nymphaeoideae. The occurrence of both Nymphaeaceae and Cabombaceae (e.g., Pluricarpellatia peltata) in the Lower Cretaceous contradicts recent molecular dating implying a Late Cretaceous–Early Tertiary divergence for those families. Furthermore, the morphology of the fossil and sedimentologic and taphonomic data indicate that Jaguariba gen. nov. had an aquatic ecology similar to living Nymphaeaceae. Thus the taxon was part of the aquatic vegetation of the Crato lake in association with Pluricarpellatia peltata, an earlier described cabombaceaen aquatic angiosperm.
