Longest dinosaur ever

[lio99]

Hi guys
could one of you give me a list of the longest dinosaurs ever because i am not 100% sure that it is the a amphicoelias or bruhathkayosaurus.

[zopteryx]

According the Princeton Field Guide to Dinosaurs by Gregory S. Paul, the biggest dinosaurs
(which I'd consider 25 m/80 ft +) are:

Hudiesaurus -- 25m/80ft
Mamenchisaurus (M. sinocanadorum) -- 35m/115ft
Turiasaurus -- 30m/100ft
Barosaurus/Tornieria -- 25m/80ft
Diplodocus -- 25m/80ft
Seismosaurus -- 32m/105ft
Amphiocoelias -- 60m/150ft (maximum)
Supersaurus -- 35m/110ft
Sauroposeidon -- 27m/90ft
Ruyangosaurus -- 30m/100ft
Argentinosaurus -- 30m/100ft
Puertosaurus -- 30m/100ft
Futalognkosaurus -- 30m/100ft
Pellegrinosaurus -- 25m/80ft
"Antarctosaurus" giganteus -- 30+m/100+ft

Many of these sauropods are known from minimal remains, so most of these lengths are speculative.

And just for fun some other dinosaurs that were the largest, or one of the largest, members of their group:

Spinosaurus -- 14m/45ft (greater lengths are possible)
Giganotosaurus -- 13m/42ft
Carcharodontosaurus -- 12m/40ft
Tyrannotitan -- 13m/42ft
Tyrannosaurus -- 12m/40ft
Therizinosaurus -- at least 10m/33ft
Plateosaurus -- 9m/30ft
Ankylosaurus -- 7m/23ft
Triceratops/Eotriceratops/Torosaurus -- 8.5m/28ft
Iguanodon -- 8m/26ft
Zhuchengosaurus -- 16.5m/55ft
Edmontosaurus/Anatosaurus/Anatotitan -- 9m/30ft
Saurolophus -- 12m/40ft

[Meso-Cenozoic]

Amph is estimated to be longer than Bruh, but Bruh is suppose to be heavier.

This site I found to have generally good basic info. (Although the notion that dinos are reptiles is a bit old-school.)
