Colors Of Modern-day Birds’ Eggshell Linked To Ancient Ancestral

Headlines Science

The tiny harmless birds like sparrows can ever be connected to the vicious and mighty dinosaurs like Tyrannosaurus rex is quite shocking and is something unthinkable. After a detailed study, there has been a connection found. The recent research has been able to link the ancient ancestors and modern avians. The researchers from Yale University, the University of Bonn, and the American Museum of Natural History have found that the birds’ eggshell coloration has evolved from the dinosaurs something that can be concluded as an independent trait.

The variation in the colors of the eggshells can be seen right from the American Robin’s egg to the Jackson Pollock-esque. The diversity in the color patterns in the modern avians basically is derived from two pigments such as red and blue or blue-green biliverdin and red-brown protoporphyrin IX. The birds have been well thought-out as exclusive owing to their eggshell colors which are similar to the coloration found in the ancestral dinosaurs. The researchers used the instruments like a non-destructive laser method and Raman microspectroscopy to identify the two pigments in 18 of the fossilized dinosaur eggshells found from around the world. The pigments were found in the Eumaniraptoran dinosaurs’ eggshells and these belong to theropods group such as velociraptors which are assumed to have evolved into the modern birds.

The research also found that the eggs of the dinosaurs burying their eggs tend to have no pigments whereas the eggs of the open nesting theropods are being held responsible for the egg coloration evolution. According to lead researcher Jasmina Wiemann from Yale University, the ecological, reproductive, and nesting behaviors does not fossilize thus the egg color is the only best substitute. The new research is set to open new doors for more studying on the subject and also on the surface nest eggs plus egg color pigmentation. The modern birds are being considered to a part of the pedigree of the dinosaurs. A Paleontologist Adam Marsh at Petrified Forest National Park has made a novel, detailed anatomical report of the finest conserved specimens of a car-sized sauropod that can supposedly help the palaeontologists in untying the ambiguity of why several dinosaurs got so gigantic in a recent study.
