Показать описание
What was the largest dinosaur? And how did it get so big? If you're shouting 'Diplodocus!' and 'Brachiosaurus!', you're on the right track.

Sauropods such as these were enormous. But the true champions were the titanosaurs, the last-surviving group of long-necked sauropods. Titanosaurs such as Puertasaurus, Patagotitan and Argentinosaurus were the longest and heaviest dinosaurs of them all. In fact, they were by far the largest animals to ever live on land.

Watch our animation to find out how these dinosaurs were able to grow so big and what this meant for their survival.

That Triceratops walking sadly away in defeat was hilarious!

Looking forward to seeing the Patagotitan when it arrives at the NHM. Went to see my old chum Dippy in Coventry last weekend, which was also a treat!

I'm curious if the Natural History Museum to create a series of video clips of different facts about The Titanosaur for my documentary-styled special video for my Future Is Prehistoric Series called The Titanosaur: The Story Of The Giant Dinosaurs.

Sauropods show that eating plants is beneficial for every species 😄

Sauropods. Didn't exist as far as I'm concerned.
Btw. I'm not saying all dinosaurs just saurpods

An elephant eats 150 kg per day and spends 18 hours eating per day

An Argentinosaurus needs 850 kg per day
So please explain how many hours it would need to be eating per day? Because upscaling it would seem like 100 hours eating per 24 hours period

So what am I missing?
Did vegetation back then contain 10 times as much nutrition?

Please explain. Because based on what I know about elephants. Saurpods seem impossible. Biologically.

I have not found an explanation so far🤷‍♂️🤷‍♂️
