Context: <response>: ```To the north of Africa di Tethys Sea still dey narrow. Broad shallow seas dey advance across central North America (the Western Interior Seaway) and Europe, then e come recede late for di period, e leave thick marine deposits sandwiched between coal beds. At di peak of the Cretaceous transgression, one-third of Earth's present land area dey submerged. The Cretaceous dey famous for im chalk; indeed, more chalk form for the Cretaceous pass any other period for the Phanerozoic. Mid-ocean ridge activity—or rather, the circulation of seawater through the enlarged ridges—enriched the oceans in calcium; this made the oceans more saturated, as well as increased the bioavailability of the element for calcareous nanoplankton. These widespread carbonates and other sedimentary deposits make the Cretaceous rock record especially fine. Famous formations from North America include the rich marine fossils of Kansas's Smoky Hill Chalk Member and the terrestrial fauna of the late Cretaceous Hell Creek Formation. Other important Cretaceous exposures occur for Europe and China. For the area wey be India now, massive lava beds wey dem call the Deccan Traps dey laid down for the very late Cretaceous and early Paleocene.```
