My statement: "The Jehol Biota seems to have evolved in situ from the preceding Daohugou Biota without any strongly defined division" was reverted by a user who demanded citations. Since my statement merely proceeds from my reading of Daohugou Beds, I've simply lifted the supportive reference and repeated it here. If any editor doesn't like the result, feel free to improve it, supplying citations of course. --Wetman (talk) 01:30, 1 April 2010 (UTC)Reply

Well, I don't like it but thanks for the cite ;) I'll have to dig up any number of papers which counter the claims in that one when I get home. Also not really fair to single out Daohugou when other formations have been suggested as the earliest Jehol stages, under more rigorous definitions of the Jehol biota.

'"paramocellodid" lizards

edit

"Paramocellodid" returns no hits at GoogleScholar and may be considered obscure enough to warrant either an explanatory phrase or the substitution of a more widely-used taxonomic category.Wetman (talk) 15:07, 17 September 2016 (UTC)Reply

Hi,

In the first paragraph, a link to the tephra article and a new reference was added.--Mikabella95 (talk) 20:42, 20 March 2020 (UTC)Reply

New report claiming Jehol Biota lived at a high altitude

edit

I thought this new research might be worthy of appending to the article if it's alright with you guys:

High-altitude and cold habitat for the Early Cretaceous feathered dinosaurs at Sihetun, western Liaoning, China

During the Early Cretaceous, the Jehol Biota, especially the unique feathered dinosaurs, flourished in western Liaoning Province, China. As insulation devices, the feathers helped these nonavian dinosaurs resist the cold climate, although conventional opinions have suggested that the Early Cretaceous was a typical “greenhouse climate” world. Based on the clumped isotopes of the paleosol carbonates in the Sihetun area, our study estimates the paleotemperature and paleoaltitude of the living habitat of these feathered dinosaurs during the Early Cretaceous. We suggest that the feathered dinosaurs in NE China lived in a high-altitude habitat with frozen winters and volcanic eruptions, which implies possible climate-influenced evolution of the feathered characteristic of the dinosaurs. We also suggest that topographic change-induced cooling was caused by significant tectonic regime transformation in East China.
