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!

Good list. I'd add pics myself, but that's just me. I got a thing for top 10s, so I always appreciate a good one.

I like the list even though I already herd of all of these. And it's all right to not have pictures I never have any and hey people like my threads, I hope. Btw I have a series that is only about top 10s list.

I do find some of these sizes to be a tad high(the 9 ton Oxalaia for example), but the species chosen are good :)

I can understand that, after all a lot of these theropods have not been studied very well (that is sort of why they are on this list). I just looked at a lot of their closest relatives and went off of that, although that is definitely not the best way to get their sizes.

This is a good list, I never heard of Rapator and Beishanlong before!

I heard that Becklespinax was actually a new genus of torvosaur, but I consider the source unreliable b/c I don't have the link, nor do I remember the website.  Would anyone here think that there is some validity in that hypothesis?

I know when they first found it they classified it as a species of Megalosaurus, which is a close relative of Torvosaurus. Although I think the only Megalosaurs (Torvosaurs) that survived into the cretaceous were the Spinosaurs, except for some possible fossils of Afrovenator and that one theropod from New Zealand. But it is possible that it might have been a Megalosaur, especially because Megalosaurs were abundant in Europe during the Jurassic period.

Let me guess, you've heard of Oxalaia, Epanterias, Zhuchengtyrannus, and Siats. Anyways, thanks!

Personally, I've heard of all of these. But then again, I've been studying dinosaurs since age 2(ok, so not really studying then, but still).

Lets just admit it, anydody who didn't want to be a paleontologist at that age probably did not have a normal childhood.

I can see that, yes, lol. Of this list, "Z-Rex" is my favorite...

Yeah Zhuchengtyrannus is pretty cool. You being a Tyrannosaur expert, I actually have a question to ask about Zhuchengtyrannus. Did Zhuchengtyrannus have binocular vision like Tyrannosaurus? I know Tarbosaurus didn't, so thats why im asking that.

Same, I loved Dinos since I could first talk. My first movie was walking with the dinosaurs. And I am sure you love z- rex because it is the closest to t.rex.

And yes all tyrranosurs did though t.rex had the best. Zuncheng had a lesser vision because they were more placed on the side then forward as in t.rex. it provably ressembled tarbosaurus in terms of skull shape/size. Any more questions just PM me.

Hard to say for sure since a full skull isn't known. However, it seems Tarbosaurus was it's closest relative. If Zhuchengtyrannus had binocular vision, it was pretty limited.

And TK, not all tyrannosaurs had it. Tarbosaurus and Albertosaurus for example. Their vision was kind of limited. Better than earlier carnivores like Allosaurus, but not fully binocular either.

I meant they had at least some binocular vision.

Nice list. The the general population most likely hasn't heard any of these. However, I've heard of all but Beishanlong and Rapator. Interesting creatures they all are though.

Oh I see, so it sort of had a combination of Binocular vision and Monocular vision.
