Ask Dinosaur George #28

You're great Dinosaur George!

Dinosaur George, I agree with you about the T-Rex vs Triceratops fight. It would certainly be epic, but I agree that it was probably rare. I honestly, because Triceratops is so well defended, don't think T-Rex would attack Triceratops, unless it was REALLY hungry and there was nothing else around to hunt.

George, Do You Reckon Megaladon Is Still Alive Todate?

[centrarchid]

George says that birds and pterosaurs aren't related at all but if pterosaurs are related to dinosaurs than of course birds are related to pterosaurs. Dinosaurs and pterosaurs both fall within Ornithodira (Avemetatarsalia) a clade within Archosauria so while pterosaurs may not be dinosaurs, they most certainly are related.

Dear Mr . Dinosaur George, do you think in Mesozoic era, especially in Cretaceous Period, there were a feathered dinosaurs existed, which adapted to the water like today's ducks and geese?

In America, I heard there are fossils of ducks were found in Cretaceous Formation. It tells that the ancestor of water-birds before T-Rex appears. How do you think sir?

@ayu1ban i dont think he's going to comment back...lol

[KevinLeeAshby]

what are the weapons on megalania that make you think that it owns that honor?

[GamingGenius]

@KevinLeeAshby I can probably answer that. Megalania has very sharp teeth and a whiplike tail, but he also has a secret weapon. Like his Komodo Dragon cousins, Megalania also has venom glands in his lower jaws. It was originally thought that Komodos had very high bacteria levels in their drool and this was what killed their prey, but it's been discovered that they have venom glands similar to the Gila Monster's venom glands.

Darren Naish believes that the nibbling front teeth of theropods may have also been used in grooming.

[dinosaurgeorge]

Very nice. Dr. Bakker agrees with you. One day we were looking at a rex skull, and he gave me his insight into the design of the front teeth,and how he thought that were used from grooming. Very interesting stuff.

[Muppephile]

Wow, it's great to hear that Bakker keeps up with the latest theories. Of course, I also remember hearing that theropods may have used those teeth to nip the last shreds of meat from hard-to-reach parts of a carcasse.

Hey Dinosaur George! Thank you for answering my questions about megalania on video. There will be more questions on megalania for you soon, and I hope you're able to answer them.
