No.They went extinct 65 million years ago

well, they aren't equally similar, but they are similar, they cant fly -like a penguin- and it can swim fast and eats fish -like a penguin- but its still a bird -which is gay-

That would be Barney.

Actually it would depend on which one you are talking about. Hesperornis is the penguin like dinosaur with long legs and next to nothing for arms. Archaeopteryx is a not so attractive bird. Daspletosaurus looks like its relative T-Rex. Confuciusornis would be the attractive bird. or the Corythosaurus. The best answer for you is to look at PBSkids.org and look at the dinosaur train segment.

No dinosaurs live in the ocean. Here is a list of prehistoric sea creatures:

1. Cretoxyrhina

2. Caproberyx

3. Dolichorhynchops

4. Enchodus

5. Gillicus

6. Hesperornis

7. Kronosaurus

8. Liopleurodon

9. Megalodon (Biggest shark of all time. As long as 6 cars)

10. Mosasaur

11. Nothosaur

12. Platecarpus

13. Plesiosaur

14. Protostega (Ancestor of all sea turtles)

15. Styxosaurus

16. Temnodontosaurus

17. Tylosaur

18. Bananogmius

19. Basilosaurus

20. Elasmosaurus

21. Leptocodon

22. Baculite

23. Tusoteuthis

24. Cretoxyrhina

25. Squalicorax

26. Xiphactinus

During the late Cretaceous, about 90 to 70 million years ago, Louisiana was submerged under the warm and shallow Western Interior Seaway. Here, animals like Ginsu sharks, plesiosaurs, mosasaurs (huge, carnivorous, marine lizards), huge turtles called Archelon, and even Hesperornis (a fully aquatic bird), lived there. The waters were also fished by flying birds called Icthyornis.

Note that some of these organisms are speculative; the reason being that they were found in very nearby areas with exactly the same habitat and at the same time.
