Hints of fossil DNA discovered in dinosaur skull

https://www.nationalgeographic.com/science/2020/03/hints-of-dna-discovered-in-a-dinosaur-fossil/?cmpid=org=ngp::mc=crm-email::src=ngp::cmp=editorial::add=Science_20201223&rid=5DFCB8A357462614CEB0AA39E8AF8E74

Evidence of proteins, chromosomes and chemical markers of DNA in exceptionally preserved dinosaur cartilage - https://academic.oup.com/nsr/article/7/4/815/5762999


More than 70 million years ago in what's now Montana, the plant-eating hadrosaur Hypacrosaurus stebingeri roamed. A new study of H. stebingeri nestlings has found fossils of dividing cells, nuclei, and chromosomes?as well as tantalizing hints of preserved DNA.

One-of-a-kind dinosaur removed from Brazil sparks backlash, investigation

https://www.nationalgeographic.com/science/2020/12/one-of-a-kind-dinosaur-removed-from-brazil-sparks-legal-investigation/?cmpid=org=ngp::mc=crm-email::src=ngp::cmp=editorial::add=Science_20201223&rid=5DFCB8A357462614CEB0AA39E8AF8E74

A maned theropod dinosaur from Gondwana with elaborate integumentary structures - https://www.sciencedirect.com/science/article/abs/pii/S0195667120303736


The dinosaur Ubirajara jubatus is the first known non-avian dinosaur with unusually prominent shoulder feathers. The fossil also has sparked controversy amid concern that the fossil's 1995 export from Brazil may have been illegal.

The Role of Sibling Competition and Parental Provisioning on Food Distribution among Ferruginous Hawk Nestlings

https://bioone.org/journals/journal-of-raptor-research/volume-54/issue-4/0892-1016-54.4.376/The-Role-of-Sibling-Competition-and-Parental-Provisioning-on-Food/10.3356/0892-1016-54.4.376.short

Quote: Instead, the first-hatched and second-hatched nestling gained more food by competition, and the third-hatched nestling gained more food through parental allocation.

Partial Incubation and Hatching Asynchrony in the Red-Shouldered Hawk (Buteo lineatus)

https://bioone.org/journals/journal-of-raptor-research/volume-54/issue-4/0892-1016-54.4.364/Partial-Incubation-and-Hatching-Asynchrony-in-the-Red-Shouldered-Hawk/10.3356/0892-1016-54.4.364.short

Quote: Hatching patterns were the result of both the egg-laying intervals and the pattern of partial incubation, which may represent an adaptive mechanism to reduce the hatching interval while maintaining the hatching asynchrony.
