October 31, 2018 -Birds are the only living amniotes with coloured eggs1–4, which have long been considered to be an avian innovation1,3. A recent study has demonstrated the presence of bothred-brown protoporphyrin IX and blue-greenbiliverdin5—the pigments ... October 31, 2018 -And last year, molecular paleobiologist Jasmina Wiemann of Yale University published the first evidence of dinosaur egg coloration, using chemical analysis to detect two pigments—blue-green biliverdin and red-brown protoporphyrin—in the ...
We applied high-resolution Raman ... colour pigments were preserved in all eumaniraptorans:egg colour had a single evolutionary origin in nonavian theropod dinosaurs.... March 10, 2017 -Paleontologists working with fossilized eggs from a dinosaur called an Oviraptor, found that the eggs contain a mix ofblue-greenpigments.
Unsurprisingly, the experimentally-stained eggs were probably not as bright as they were before fossilization. January 12, 2022 -These compounds are important for ... of this particular dinosaur - a beaked, feathery dinosaur called an oviraptorid - wereblue greenin color....
June 17, 2020 -Then, in 2015, Jasmina Wiemann and colleagues reported the presence of two pigments,one blue-green and one red, in oviraptor eggs. But that was one dinosaur. February 20, 2024 -The discovery adds to a growing body of evidence from fossil pigments that is revolutionizing dinosaur science.
The first hints egg color might have originated in nonavian dinosaurs came last year, when Jasmina Wiemann, a PhD student at Yale University, and her colleagues announced their discovery of the pigment responsible for blue-green egg color in fossilized eggshells of several oviraptorid dinosaurs from China. August 29, 2017 -Such a nest arrangement corresponds with our reconstruction ofblue-greeneggs for oviraptors. According to the sexual signaling hypothesis, the reconstructedblue-greeneggs support the origin of previously hypothesized avian paternal care ...

Mesozoic Era. Theropod eggshells could bevarious shades of blue-green and some (like Deinonychus eggs) even had red-brown speckles on them!...
