Characteristics of Early Cretaceous wildfires in peat-forming environment, NE China

open access: yesJournal of Palaeogeography, 2019
Inertinite maceral compositions in coals from the Early Cretaceous Erlian, Hailar, and Sanjiang Basins in NE China are analyzed in order to reveal palaeowildfire events and palaeoclimate variations.

A turiasaurian sauropod dinosaur from the Early Cretaceous Wealden Supergroup of the United Kingdom [PDF]

open access: goldPeerJ, 2019
The Jurassic/Cretaceous (J/K) boundary, 145 million years ago, has long been recognised as an extinction event or faunal turnover for sauropod dinosaurs, with many ‘basal’ lineages disappearing.

Ecomorphological diversification of squamates in the Cretaceous [PDF]

open access: yesRoyal Society Open Science, 2021
Squamates (lizards and snakes) are highly successful modern vertebrates, with over 10 000 species. Squamates have a long history, dating back to at least 240 million years ago (Ma), and showing increasing species richness in the Late Cretaceous (84 Ma ...

A new hadrosauroid dinosaur from the early late cretaceous of Shanxi Province, China. [PDF]

open access: yesPLoS ONE, 2013
BackgroundThe origin of hadrosaurid dinosaurs is far from clear, mainly due to the paucity of their early Late Cretaceous close relatives. Compared to numerous Early Cretaceous basal hadrosauroids, which are mainly from Eastern Asia, only six early Late ...
