Cretaceous

The Cretaceous is a geologic period and system from circa 145 - 4 to 66 million years (Ma) ago. In the geologic timescale, the Cretaceous follows the Jurassic period and is followed by the Paleogene period of the Cenozoic era.

The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels and creating numerous shallow inland seas. These oceans and seas were populated with now extinct marine reptiles, ammonites and rudists, while dinosaurs continued to dominate on land. At the same time, new groups of mammals and birds, as well as flowering plants, appeared. The Cretaceous ended with a large mass extinction. (wiki)

  • Dinosaur Provincial Park: The Dinosaur Park Formation, which contains most of the fossils from articulated skeletons, was primarily laid down by large rivers in very warm temperate coastal lowlands along the western margin of the Western Interior Seaway. The formation dates to the Late Campanian, about 75 million years ago (wiki) Also in WH Review
  • Guanacaste: The geological diversity is also of interest. It has 24,000ha of a serpentine barren (periodyte) on the Santa Elena Península, which has existed for more than 85 million years above sea level. It has pyroclastic areas in Santa Rosa NP (Miocene) and Pleistocene volcanic complexes in the region of the Orosi and Cacao volcanoes (Guanacaste NP) (AB ev)

  • Nahanni National Park: Dramatic mountain-building began approximately 110 million years ago when molten volcanic rock from deep within the earth rose to within 3000 m of the surface where it hardened and cooled. This force pushed up the sedimentary rock above and around the intrusion, creating the mountain ranges that surround the Nahanni River. (Parks Canada website)
