An article published today (Wednesday) in the journal iScience, revealed that an egg has been discovered inside a dinosaur in China that is at least 66 million years old. The swamp was discovered in an industrial park in Genzhou in southern China in 2000, but has since been preserved for more than ten years along with other fossils until a history museum was established in the province that was discovered, after which local staff began testing the swamp.
The analysis of the egg revealed that the fetus reached a length of 27 cm and probably belonged to the group of ubiquitorosaurs, dinosaurs covered with feathers that walked on two legs that lived about 66 to 72 million years ago. The feet on both sides of the body and the back are curled up along the blunt end of the egg.According to the study, this is a unique position not previously seen among dinosaurs, but similar to the way modern bird embryos lie down before hatching from the egg.
“It’s one of the best dinosaur embryos ever discovered in history,” said Pion Weissum Ma, a doctoral student in fossil fuels at the University of Birmingham who led the study, adding: For the same behavior before hatching. “
