Cretaceous Enantiornithine Bird Was First of Its Kind with Toothless Beak | Sci.News

Paleontologists have described a new species of enantiornithine bird with a toothless beak from the Jehol avifauna of China.

"The new pterosaur species lived in what is now China during the Early Cretaceous epoch, between 125 and 113 million years ago. The flying reptile belongs to Chaoyangopteridae, a family of medium-sized and high-crested #pterosaurs mostly known from Asia."

New Species of Toothless Pterosaur Discovered in China | Sci.News

Paleontologists from China and Brazil have identified a new species of chaoyangopterid pterosaur from two specimens, one of which is the most complete and well-preserved chaoyangopterid recorded to date.

Hearing from our Cretaceous ancestors: a remarkable fossil discovery in Jehol Biota

The evolution of the middle ear in early therians remains enigmatic. Our recent discovery of a detached, microtype ear in a newly uncovered Early Cretaceous eutherian mammal not only addresses this mystery, but also suggests independent decoupling of hearing and chewing apparatuses.

How #volcanic phosphorus supply boosted the Jehol Biota https://phys.org/news/2023-07-volcanic-phosphorus-boosted-jehol-biota.html paper: https://www.sciencedirect.com/science/article/abs/pii/S2095927323003419 #volcanism

"The #JeholBiota, which includes the earliest known flowering #plants, feathered #dinosaurs and early #birds, had a high level of #biodiversity and #biomass... But why was this area so rich in life during this period? Recent research suggests that the prosperity of this unique #ecosystem was closely tied to the destruction of the #NorthChinaCraton."

How volcanic phosphorus supply boosted the Jehol Biota in northern China

Have you ever heard of the Jehol Biota, a diverse assemblage of plants and animals during the Mesozoic Era that lived in what is now northern China? The Jehol Biota, which includes the earliest known flowering plants, feathered dinosaurs and early birds, had a high level of biodiversity and biomass compared to other contemporaneous lagerstΓ€tten.

Early Cretaceous Bird Had Dinosaur-Like Skull and Bird-Like Body

#Cratonavis zhui, a #NewSpecies of #birds from the Early #Cretaceous #JeholBiota, had a unique combination of a dinosaurian skull with an avian post-cranial skeleton, revealing the key role of evolutionary mosaicism in early bird diversification. On the bird evolutionary tree, it sits between members of the bird clade #Ornithothoraces and the more reptile-like #Archaeopteryx.

Paleontologists Find Fossil of 119-Million-Year-Old Beaked Bird
https://www.sci.news/paleontology/confuciusornis-shifan-11528.html Paper: https://www.nature.com/articles/s42003-022-04316-6

#Confuciusornithidae is a clade of Early #Cretaceous pygostylian #birds known from the #JeholBiota of East Asia, and represents the earliest known toothless, beaked birds. #Confuciusornis shifan weighed less than 200 grams and was smaller than most other confuciusornithid species.

The fossil record is not so simple. As Paul Olsen and Manja Hethke have pointed out, this is not what the fossil record suggests. In the Jehol Biota and elsewhere, clam shrimp like E. middendorfi are EVERYWHERE. Co-occurring with fish, in fact. The sedimentary characteristics suggest that this was not an ephemeral body of water, but a permanent body of water. #jeholbiota

#Confuciusornithids, which lived in the Early #Cretaceous #JeholBiota, are a very unusual group of early #birds. Over the past 30 years, they have been the most deeply, broadly studied avian group in the Jehol Biota.

A new specimen illuminates the story of flight evolution in an iconic group of early birds

Confuciusornithids only lived in the Early Cretaceous Jehol Biota are indeed a very unusual group of early birds. We are very lucky to encounter Confuciusornis shifan, a new member of this group. This blog post is contributed by Dongyu Hu and Corwin Sullivan.
