How much big is dinosaur egg?

I'm curious to know, just how big is a dinosaur egg? We've all heard about the massive size of these prehistoric creatures, but how does that translate to the size of their eggs? Are they as colossal as we might imagine, or are they more modest in size? Understanding the dimensions of dinosaur eggs could give us insight into the reproductive biology of these ancient beasts. So, what's the typical size range for a dinosaur egg, and how does it compare to the eggs of modern animals?
