Why dinosaur eggs didn t hatch?

Could you please elaborate on the reasons why dinosaur eggs failed to hatch? Were there any specific environmental factors, such as changes in climate or lack of sufficient nutrients in the soil, that contributed to this phenomenon? Were there any inherent defects in the eggs themselves, or were there predators that posed a threat to the hatching process? Additionally, did the evolution of dinosaurs play a role in the decreased success rate of egg hatching? I'm eager to understand the complex interplay of factors that led to this intriguing aspect of dinosaur biology.
