Early Cretaceous lepidosaur (sphenodontian?) burrows. [PDF]
Sci Rep, 2023 AbstractScarce fossil tetrapod burrows have been recorded in Cretaceous rocks, which is probably linked to the dominant equable climates that existed for most of this period. The occurrence of Cretaceous tetrapod burrows from Patagonia (Chubut Province, Argentina) dated between 118 and 115 million years ago, gives insights into their paleoecology and ...

Early Cretaceous angiosperms and beetle evolution [PDF]
Frontiers in Plant Science, 2013 The Coleoptera (beetles) constitute almost one-fourth of all known life-forms on earth. They are also among the most important pollinators of flowering plants, especially basal angiosperms.

Helminth eggs from early cretaceous faeces. [PDF]
Sci Rep, 2020 AbstractThe exceptional fossil site of Las Hoyas (upper Barremian, Cuenca, Spain) yields abundant small to medium vertebrate coprolites, hindering the search for parasites. We studied the contents of 29 coprolites that were previously classified into distinct morphotypes.

Ecomorphological diversification of squamates in the Cretaceous [PDF]
Royal 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]
PLoS 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 ...

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