Are Ostriches Related to T. rex?
The Answer:
No not really.
Ostriches are more closely related to other birds like chickens and emus than they are to any kind of dinosaur. The reason people might think they are related is because when scientists first found ostrich fossils they thought they might be related to another group of large extinct animals called theropods. Theropods include animals like T. rex and Velociraptor and they share some similarities with ostriches like having two legs and sharp claws.
However further study has shown that there are many differences between the two groups. For example theropods have a different kind of hip joint and their bones are hollow while ostrich bones are solid. Ostriches also have a different kind of respiratory system and their eggs are different.
So while ostriches might look a bit like dinosaurs they’re actually not very closely related at all.
