Labels:text | screenshot OCR: COMPARING EGG SIZES F " VEN THE LARGEST dinosaurs would have laid quite small MATASAURA EGG eggs. The reason for this is that 20 cm (8 in) long; a very large egg would have a parent 9 m (30 ft) long large volume of contents and would need to have a thick containing shell. This would prevent oxygen from passing ALLIGATOR EGG through to the embryo, and 9 cm (31/2 in) long; would be too tough for the parent 4 m (13 ft) long young dinosaur to penetrate. CHICKEN EGG 6 cm (21/2 in) long; parent EGG SIZES 70 cm (271/2 in) long Eggs of large and small creatures differ in size much less than their parents.
