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.

First evidence of ranunculids in Early Cretaceous tropics. [PDF]
Sci Rep, 2022 AbstractEarly Cretaceous floras containing angiosperms were described from several geographic areas, nearly from the Arctic to the Antarctic, and are crucial to understand their evolution and radiation. However, most of these records come from northern mid-latitudes whereas those of lower paleolatitude areas, such as the Crato Fossil Lagerstätte in NE ...

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

Flower Buds Confirmed in the Early Cretaceous of China [PDF]
Biology (Basel)The Yixian Formation (Lower Cretaceous) in China is famous worldwide for its fossils of early angiosperms, but there has been only one record of flower buds (Archaebuda lingyuanensis) hitherto, in which only the surface of the flower bud was documented while no internal details were known.

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.

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 ...

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 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.
