10 Large Theropods you've Never Heard of

Hello! In this list I am going to list 10 large Theropods a lot of you probably have never heard of. So, lets get started.

10-Oxalaia

Oxalaia was a Spinosaur and was probably the South Amercian version of Spinosaurus. Although they have not been found in the same formation, it is probably safe to assume that this theropod encountered Giganotosaurus because they lived on the same continent at the same time. Like Spinosaurus this theropod had a giant sail on its back, because of this some people think its just a species of Spinosaurus. This theropod was found in Brazil and probably was around 13 meters long and weighed about 9 tons.

9-Becklespinax

Becklespinax was the European version of Acrocanthosaurus. It was found in England and probably lived during the early cretaceous period. It was probably a Carcharodontosaur and had large spines sticking out of its back like Acrocanthosaurus, because of its similarities some people even think it wasthe same animal as Acrocanthosaurus. It was probably 10 meters long and weighed about 6 tons.

8-Epanterias

Epanterias was a close relative of Allosaurus and Saurophaganax, some people think it was the same genus as either of these two theropods. Epanterias was found in the Morrison Formation which has the most late Jurassic fossils in the world. It lived alongside its relatives Allosaurus and Saurophaganax and its more distant cousins Torvosaurus and Ceratosaurus. It probably was about 9 meters long and weighed about 4 tons.

7-Rapator

Rapator was a Megaraptorid and is so far the largest theropod to be discovered in Australia. Some people argue that this large theropod was the same as Australovenator but this is unlikely due to some difference in hand structure and the fact that the two were different in size and were seperated by 10 million years. This theropod was probably about 9 meters long and 4 tons.

6-Beishanlong

Beishanlong was probably the second largest ornithomimosaur that ever existed, only beaten by Deinocheirus which lived alongside it. Beishanlong was found in China and was probably an Omnivore. It lived alongside Deinocheirus, Tarbosaurus, Therizinosaurus, and a lot of other large theropods. It was probably about 8 meters long and about 3 tons, although analysis of the bones suggest that the specimen was not fully grown.

5-Sigilmassasaurus

Sigilmassasaurus was a theropod that was discovered in Morocco. Nobody really knows what this theropod was, some people argue that it was a Spinosaur while others argue it was a Carcharodontosaur. Whatever it was it probably was not the top predator of its ecosystem because it lived alongside large theropods like Spinosaurus and Carcharodontosaurus. It was probably 10 meters long and weighed about 5 tons.

4-Zhuchengtyrannus

Zhuchengtyrannus was a Tyrannosaur discovered in China. It lived alongside Beishanlong which I mentioned earlier on the list and it also lived alongside Tarbosaurus. It may have been the apex predator of Asia when it lived, although its possible Tarbosaurus was larger. Though some people think it was the same as Tarbosaurus. It was probably about 11 meters long and weighed about 5 tons.

3-Siats

Siats was a Megaraptorid discovered in the U.S.A. It lived alongside Acrocanthosaurus probably meaning Siats was not the top predator in its ecosystem. Recent evidence shows that Megaraptorids were probably Tyrannosauroid, if this is true that would probably make Siats the first Tyrannosaurus sized Tyrannosauroid. It was probably about 11 meters long and weighed about 4 tons.

2-Sauroniops

Sauroniops was a Carcharodontosaur discovered in Morocco, it is named after Sauron from the Lord of the Rings. Sauroniops probably was not the top predator of its ecosystem because it lived alongside Spinosaurus, Carcharosontosaurus, and Sigilmassasaurus which I mentioned earlier. It was probably about 10 meters long and weighed about 6 tons.

1-Veterupristisaurus

Veterupristisaurus was found in the Tendaguru Formation of Tanzania and is the earliest known Carcharodontosaur. It was probably the apex predator of its ecosystem. It lived alongside the oldest known Spinosaur Ostafrikasaurus and two other theropods that made it from north america, Allosaurus and Ceratosaurus. Despite being the oldest Carcharodontosaur it was also one of the biggest. It was probably about 10 meters long and about 6 tons.

Anyways I hope you guys enjoyed this list! Tell me below which of these theropods you have not heard of. Also tell me any theropods that you think nobody has heard of. Thanks!

Thanks Mr. Happy! I'm glad there was at least some you have not heard of.

Yeah, kinda like that. A limited overlapping field of vision. It's vision was good enough for hunting, that's for sure. Tarbosaurus and Zhuchengtyrannus hunted more sauropods than T.rex probably did(though it did hunt Alamosaurus from time to time) and binocular vision wasn't quite as important for hunting huge sauropods. It was more important for hunting ceratopsians and hadrosaurs, which Tyrannosaurus did more often than the other two.

That actually makes a lot of sense, because most other large theropods (Carcharodontosaurus, Giganotosaurus) had large sauropods living alongside it. Plus I read something that said that Alamosaurus was only really in the Southern United States and Mexico, meaning Tyrannosaurus did not encounter it in all of its range.

Correct. Many sauropod hunters had somewhat poor vision. And yes, T.rex territory only overlapped with that of Alamosaurus in the south, but they did encounter each other once and a while.

And there is no fossil evidence suggesting that T. Rex preyed on them (Sauropods did get big to avoid predators after all). But imagin a Triceratops charging a straight at a T. Rex with Monocular vision, the T. Rex would not even see him coming! I would actually feel a little bit bad for the T. Rex.

Alamosaurus bones with T.rex bite marks have been found. Whether this indicates predation or scavenging, we don't know.

Where were the bite marks found on the skeleton?

Either way they encountered eachother and rex did not pass up the opportunity to eat the alamosaurus.

Near the neck bones I believe. 

 

PS- found this pic interesting...

Great list. Personally, I've heard of all those before, but for sure, most people didn't (talking generally).

Also, about the Tarbosaurus and binocular vision, why wouldn't Tarbosaurus be able to see things directly in front of it? Its skull structure allows it perfectly to have eyes facing forward = good binocular vision.

The same thing goes for every advanced tyrannosaurus.

 

Also RexFan, just to point this out, Alamosaurus is unlikely to have lived with T.rex. Alamosaurus remains were foundin Texas, south USA, while T.rex is found in Montana, north USA. The gap is too big so that they could have coexisted.

I've only never heard of 7, 6, and 1.

Almost knew all of them, but Beishanlong, Veterupristisaurus and Rapator (although that one sounds kinda familiar) don't ring any bells.

Keep in mind that many people have died for their beliefs; it's actually quite common. The real courage is in living and suffering for what you believe in. -Brom-

DinoSteve, T.rex fossils have been found in the south. Nothing overly great, but some teeth, fragments, and possibly footprints have been uncovered.

Too fragmentary to confirm anything though. I'm not saying it's impossible of course, but the evidence is not enough to confirm it.

I do know that they have actually found a T. Rex in the city of Denver, Colorado. Its in a formation called the Denver Formation. They have also found Triceratops, Edmontosaurus, Ornithomimus, and Pachycepaphalosaurus there too.
