The largest a Biped can get is 14 tons(this will rule applies to all 2 legged animals so this will apply to theropods) and the Amphicoelias is 200+ tons. Spinosaurus is almost at that barrier. It is EXTREMELY unlikely that something out there is actually bigger than Spinosaurus for a land carnivore. There is a tiny chance that there was a predator only 1 ton heavier than Spinosaurus but it is unlikely we will ever know of a terrestrail predator larger than Spinosaurus. true true but it isn't impossible... Nothing would need to be that big, most dinosaurs known to hunt large sauropods were tiny compared to their prey, like Mapusaurus and Argentinosaurus. They would probably hunt in packs instead of being really damn large. Spinosaurus lives at the limit of what is possible for a biped, and it's already a slow-moving creature. It wouldn't be much faster than an Elephant while running. A theropod at 14-16 tons would be really slow, a blow from it would certainly kill anything smaller than itself, but it's not worth it because it would be really slow and hunting would be hard. That would explain why Spinosaurus fed on fish (I'm not saying it was 100% a fish-eater, it's the same thing as saying T. rex was pure scavenger, most predators scavenge if they find themselves in need), since it would not have to run. Once again I am not saying fishing is easy, but since Spinosaurus could not run really fast it would stick to that most of the time. That's what I believe.

If there was a predator larger than Spinosaurus it would have been a carnosaur.

breviparopus taghbaloutensisNOTE:Ignore the T. rex its size is bullshit Breviparopus is massive dinosaur only known from a few foot prints but is close to the size of brachiosaurus nougaredi but is slightly smaller. Its about 34-37 metres long and weighs 110-117 tons. The Taxon of this animal was a mystry for a while until a paleontologist called Michel Monbaron said its most likely a brachiosaur. He and his colleages said this. " Breviparopus is quite distinct from the prints made by Atlasaurus. However, the presence of a small medially directed thumb-claw print makes it likely the animal was a brachiosaur, since they have small thumb claws at ground level (as opposed to diplodocids and camarasaurids, whose thumb metacarpals are short and hold their thumb claws off the ground), and the narrow-gauge stance also fits with a brachiosaur body shape."
So its a really big brachiosaur very similar to Brachiosaurus Nougaredi but slightly smaller at Max size for Breviparopus but significantly smaller if you take the smaller estimate.

Breviparopus is the largest one in the chart BTW and here is the labled chart with all the names of the animals

Apatosaurus officially is on this list of largest known dinosaurs: svpca.org/years/2013_edinburgh/abstracts.pdfDo a find for Apatosaurus and you'll see what I mean. A new specimen of Apatosaurus (nicknamed the Oklahoma Giant) was recently announced at the Symposium of Vertebrate Paleontology and Comparative Anatomy by Matt Wedel, and has bones roughly 11-30% larger (linearly) than the previous record-holder. The OK Giant is estimated to be somewhere between 36 and 80 tons, which makes it alone among the ranks of many big Titanosaurs, but that's not all. The OK Giant also has a visible neurocentral fusion line and a cervical rib which is unfused, both of which are features seen in skeletally immature sauropods. This means that despite being so big, the OK Giant (and all other known Apatosaurus specimens) is still a juvenile, and according to Wedel's estimates, it was less than 80% linear size, or about 50% adult size. So, when half-grown Apatosaurus exceeded the maximum known adult size of Supersaurus and Brachiosaurus and rivaled the largest Titanosaurs known, and full-grown adult Apatosaurus are completely unknown, but may have even gotten into the Amphicoelias-range.

That is an amazing discovery, Apatosaurus is really one large animal. Thanks for sharing this info with us.

Amphucoelias or however you spell that is the all together largest to our current knowledge being 58 meters long and weighing around 120 tons. However there are theories that there was another sauropod that could have weighed as much as 200 tons but that again is just a theory.
