Pollination of Cretaceous flowers [PDF]
Proceedings of the National Academy of Sciences, 2019 Insect pollination of flowering plants (angiosperms) is responsible for the majority of the world’s flowering plant diversity and is key to the Cretaceous radiation of angiosperms. Although both insects and angiosperms were common by the mid-Cretaceous, direct fossil evidence of insect pollination is lacking.

The Late- Cretaceous volcanic rocks from Talesh area (western Alborz): chemical variation, crystallization condition, hygrometry and tectonic setting [PDF]
پترولوژی, 2020 In the Talesh area (western Alborz), a thick sedimentary- volcanic association formed in a littoral- deltaic environment during the Late Cretaceous. The extrusives comprise volcanoclastics (tuffs), lava flows (pillow and massive) and basic dykes.

Deep Underground Science and Engineering, Volume 1, Issue 2, Page 148-164, December 2022., 2022 We conducted a new approach of mine water‐deep geological storage, the results showed that the hydrogeological feasibility of Baotashan coarse sandstone (BCS) was impressive and useful for real project. The effective porosity of BCS aquifers ranged from 1.36% to 3.46% and the capacity of mine water geological storage was 0.455–1.266 Mm3 for 1 km2 in ...

Comparative osteohistology of Hesperornis with reference to pygoscelid penguins: the effects of climate and behaviour on avian bone microstructure [PDF]
Royal Society Open Science, 2014 The broad biogeographic distribution of Hesperornis fossils in Late Cretaceous Western Interior Seaway deposits has prompted questions about whether they endured polar winters or migrated between mid- and high latitudes.

Diversification of Rosaceae since the Late Cretaceous based on plastid phylogenomics.
New Phytologist, 2017 Phylogenetic relationships in Rosaceae have long been problematic because of frequent hybridisation, apomixis and presumed rapid radiation, and their historical diversification has not been clarified.
