... the Boreal and Tethys domains. Along the northern portion of that seaway, close to the Boreal Sea, early diagenesis of the Torrecilla fringing reef complex was controlled by rising sea level and by local tectonism, leading to alternations of submergence and reefal exposure. While exposed, reef corals were...

.... Widespread removal of Portlandian and Kimmeridgian enhances the sand and mud contents respectively; and, broadly, in that order. Salinities in the S England basin are controlled by the effectiveness of coastal protection against advances by the Boreal sea into the Londinia-Cornubia gap. During arenaceous...

... the northern border of Laurasia (Boreal sea), and a second along the southern border of Gondwana (South Pacific Sea); however, if these two last could be effectively used for faunal exchanges and migrations, they are poorly documented. Near the end of the Aalenian, the Ammonitina sub-order undergoes a strong...

... conditions, and the presence of agglutinated and calcareous foraminifera indicate meso- to polyhaline marine salinities. These assemblages suggest that overall marine salinity levels of the encroaching Boreal Sea may have been lower than normal (i.e. sub-euhaline) in the Western Canada Sedimentary Basin...

... of the trough coupled with a eustatic rise in sea level resulted in a major transgression of the Deep basin from the north by the Boreal sea. This event is represented by the coastal and shallow marine sandstones of the Bluesky Member. The Bluesky was capped by the marine shales of the Moosebar Formation...

...Claudia J. Schröder-Adams; Per Kent Pedersen Abstract During Albian time the Western Interior Sea formed an embayment of the northern Boreal Sea and paleogeography, depositional processes and relative sea level were controlled by a global sea level rise and active thrusting within the Cordillera...

Major northwest-trending fluvial systems were encroached and ultimately an interior seaway was extended into Montana. In Albian time, a terrigenous influx of Cordilleran origin prograded upper Mannville coastal and continental...

... sediments of the Boreal Realm (Norwegian Arctic, Barents Sea area). The morphology of these pollen grains is comparable to forms recorded from the Early Cretaceous, which are generally attributed to angiosperms. The new finds of angiosperm-like pollen are the earliest in the fossil record so far and show...
