Some mosasaurs were larger than a T-rex, with the smaller ones being about the size of a dolphin. What intrigues you the most about these great marine reptiles?

It boggles the mind to think that creatures like this used to roam the same Earth we do. Nature is amazing.

Why does that Mosasaur looks like he would be the villain in a animated movie about fish?

Mosasaurus is basically the T rex of the sea

I just want to say, the narrator is perfect. She has such a smooth and comforting voice. I don't know why but I just wanted to compliment her.

If Mosasaurus were alive today, nature documentaries would say "they generally avoid humans" 😂

[AzlianaLyana]

Looks like this beasts used to be everywhere. But then again, we used to have one supercontinent anyways. Thanks for sharing National Geographic.

I’ve actually had the pleasure of being able to discover and dig up some of these in northwest Kansas.

This is beyond fascinating! My 6 year old son just became homeschooled and this is the dinosaur he chose to research. We are learning about how the asteroid that hit the GOM effected and caused extinction to almost all living dinosaurs. Thank you for this information!

Mosasaurs straddle that fine line between cute and scary. I love them!

[chewedupgum]

The thumbnail made me spit out my drink, why does it look so goofy lmao ?

[BDZILLA]

🇧🇷 I LOVE the way this lady narrates the video. Her voice is super enjoyable and plesurable to hear.

[SMDoktorPepper]

It is amusing how it starts saying how deadly they were, then give it the goofiest animation ever.
