Argentinosaurus for JP4?

While it would be cool, I've got one word to say no: Brachiosaurus

I agree with MrHappy. Argentinosaurus is a titanic dinosaur, but Brachiosaurus has already established itself as the "biggest dinosaur" in JP. It'd be like the situation with Rex being replaced(although not as extreme). Not to mention the fact I'm sure they're focussing on new predators more than new herbivores.

I agree with them two. Maybe the most likely chance to get another sauropod apart Brachio, is Mamenchisaurus.

Maybe they'll have Brachiosaurus and one other sauropod. Mamenchisaurus and Argentinosaurus were both probably shorter than Brachiosaurus, so if they're walking alongside Brach, it'll still "look" bigger. If that makes sense.

Agree with you. I'll be happy if at least Brachio returns.

i'm totally not agree ! Brachiosaurus Is The tallest creature ever exists but theres another sauropod that catches my eyes and it is the Seismosaurus ! it is the longest creature ever exist because the adult can streched for almost about 53 meters long !

Brachosaurus was not the tallest.

Also, Seismosaurus turned out to be a larger-than-usual Diplodocus. Some 30m long, not 50m.

You have to remember that dinosaur had an "Indeterminante Growth" so if a seismosaurus live long enough, had plenty of food and no predator it could reach up to 50 meters long.

Probably.

The distinction between Seismosaurus and Diplodocus is sketchy though. 50 meters is a reasonable upper estimate with 40 meters being a good average size.

PS- Sauroposeidon was likely the tallest dinosaur at about 18 meters tall.
