Dinosaur Bone Study Unveils Varied Growth Patterns Among Giants.
A study of 42 different dinosaur species, published in Science, reveals that the "get big fast" mode of growth was less predominant than researchers have assumed. The study shows that some dinosaurs grew slowly, while others grew quickly. Understanding growth strategies helps explain why some dinosaurs got enormous while others stayed small. The study also provides insights into the key developmental or genetic mechanisms underlying body size variation across animals.
