Resisting the urge to Um Actually this dragon novel because it has the dragon eggs be like three or four feet wide but there is simply a limit to how large hard-shelled terrestrial eggs can be. No matter how large the animal is, the embryo needs oxygen, and oxygen needs surface area. The larger an object is, the lower its surface area relative to volume, and the less oxygen the embryo can receive. We think of large animals as having porportionately large young because mammalian pregnancy has the unique benefit of allowing for the size of the young to scale with the adult because their oxygen is provided directly through the placenta, and almost all the megafauna remaining on Earth are mammals. But this is not the case for species which lay eggs! For fuck's sake even the sauropods hatched out of eggs barely larger than basketballs! Your hatchling dragon would be impressively enormous if it were the size of a house cat. Stop trying to make me believe that this (ROUND!) dragon egg somehow supplied enough oxygen to develop an infant the size of a large dog or even bigger. If it were possible the dinosaurs woulda been doing it!!!!
I love you /lh. Experts going off on their particular fascinating cool topics and adding unexpected context to things we take for granted is like my favorite thing this was delightful. Talk to me more about eggs and geometry and biology all you want :D
Amazing concept
OK so now can we reverse it and maths out the minimum atmospheric oxygen pressure based on the described size of a dragon egg?
What does it say that my immediate response was to start imagining how an egg might be larger and yet have an adequate surface area to provide appropriate quantities of oxygen and my instant solution was PINE CONE DESIGN EGG
... Suddenly the common modern depiction of dragon eggs covered in scales makes sense, they're not dragon scales, they're additional surface area for diffusion
