On impact and volcanism across the Cretaceous-Paleogene boundary
Science, 2020 An impact with a dash of volcanism Around the time of the end-Cretaceous mass extinction that wiped out dinosaurs, there was both a bolide impact and a large amount of volcanism. Hull et al. ran several temperature simulations based on different volcanic

A New Species of Radula (Radulaceae, Porellales) From Mid‐Cretaceous Kachin Amber [PDF]
Ecology and EvolutionThe liverwort genus Radula, one of the largest genera within the order Porellales, is phylogenetically isolated and widely distributed, with many species thriving as epiphytes in diverse ecosystems. Fossil records of Radula are scarce, particularly those

Rapid recovery of life at ground zero of the end-Cretaceous mass extinction
Nature, 2018 The Cretaceous/Palaeogene mass extinction eradicated 76% of species on Earth1,2. It was caused by the impact of an asteroid3,4 on the Yucatán carbonate platform in the southern Gulf of Mexico 66 million years ago5, forming the Chicxulub impact crater6,7.
