Evolution of Carnivorous Dinosaurs
When it comes to carnivorous dinosaurs, they can generally be classified into two groups – large and small, with very few medium-sized dinosaurs in between. This is quite different from modern carnivore communities, which showcase a diverse range of sizes. It raises an interesting question: why were there so few medium-sized carnivorous dinosaurs in the fossil record?
One theory suggests that the rapid growth of juvenile carnivorous dinosaurs, such as the mighty Tyrannosaurus rex, could have played a role in the extinction of medium-sized dinosaurs. As these juvenile dinosaurs grew into gigantic creatures, they might have outcompeted their medium-sized counterparts for resources, making it difficult for them to survive.
Alternatively, another theory proposes that we simply haven’t discovered the fossils of medium-sized carnivorous dinosaurs yet. Paleontological research is an ongoing process, and there may be many fascinating discoveries waiting to be unearthed.
