Top Ten Weirdest and Most Bizarre Dinosaurs

The Top Ten
1 Masiakasaurus

Very poorly known, so it really deserves a spot. I mean, it's teeth are just so scary yet surprisingly cool and bizarre.

2 Pelecanimimus
3 Concavenator

The Concavenator is a weird dinosaur with a weird bone on its back! Its very weird.

4 Sharovipteryx
5 Procompsognathus
6 Therizinosaurus Therizinosaurus is a genus of very large therizinosaurid that lived in Asia during the Late Cretaceous period in what is now the Nemegt Formation around 70 million years ago.

No dinosaur will ever be as weird and bizarre as Therizinosaurus and it's kin. It's a theropod, so you'll be expecting it as a carnivore judging by it's infamous claws when in reality it's a herbivore that used it's claws as either defense or to pull branches towards it. Another amazing factor is that when it was first discovered, scientists speculated that it was a gigantic turtle. Heck, it even looks like a reptilian sloth!

Who did you expect? This dinosaur is just so weird that it is actually really cool. Man, with 1-meter long claws, you'd be thinking that this is going to be one terrifying monster yet it is a herbivore despite its status as a theopod! And plus, even it's whole family tree is consisted of herbivores. Therizinosaurus still stands out as the most bizarre and weirdest dinosaur in existence. Also, don't get fooled, this beast can sure slice up a Tarbosaurus with it's awesome claws :)!

7 Spinosaurus Spinosaurus is a genus of theropod dinosaur that lived in what now is North Africa, during the lower Albian to lower Cenomanian stages of the Cretaceous period, about 112 to 97 million years ago.

Spinosaurus is one of my favourite dinosaurs ever, probably in my top 3. And No, I'm not going for Jurassic Park III.

Partly why I love Spinosaurus is because of how unique and bizarre it looks. No dinosaur could be just as ridiculous-looking as that (Maybe except Therizinosaurus, but who cares). It's a fish-eater, despite being, well, theropod and that snout just steals people's attention. The sail itself just makes it's appearance more appealing and lastly, it's a quadrupedal animal. And that's coming from a theropod, something that always walks on two feet.

I don't think it holds a candle to the Rex, but I love Spinosaurus for being it's own. Weird, big and just amazing to look at, It's one dinosaur you wouldn't think about until actually seeing it :).

You certainly can't forget about this monster after seeing JPI!. Spinosaurus gets this spot mainly due to it's bizarre snout, body structure, the tall spines on it's back and (possibly) for being a piscivore. It's actually hard to imagine that the largest theropod dinosaur would actually be spending most of it's time on the shores munching up some tasty seafood!

8 Ornitholestes
9 Amargasaurus Native to what is now Argentina, Amargasaurus is a sauropod dinosaur from the Early Cretaceous period. It features distinctive, elongated neural spines on its neck and back, possibly for display or protection. Unlike other sauropods, it was relatively small, measuring about 30 feet in length.

A small sauropod with long, spiky spines on it's back formed into a double sail, now that's genius for something like Amargasaurus.

10 Carnotaurus Carnotaurus, meaning "Meat eating Bull" in Ancient Greek, is a genus of abelisauridae theropod dinosaur that lived in what is now South America about 70 million years ago in the Late Cretaceous period.

I wouldn't forget my third favorite dinosaur on this! Carnotaurus sure does look weird. A bulldog-like head, a well preserved body with bony bumps on it's back and surprisingly puny arms are just as enough to make this land on this list. Oh, and it looks demonic too :).

I always found Carnotaurus to be one my favorites, and it, well... Looks like a bull/dinosaur. It's long legs for speed make this big-headed dinosaur look very interseting while running. Or so I presume.

One of the theropods who were capable of wiping out humanity!

The Contenders
11 Mononykus

Small, puny and very poorly known. But however, this guy has only one finger and just looks kind of weird to me as well.

Is it stranger that the bird Masked Lapwing also has one finger?

12 Dilophosaurus Dilophosaurus is a genus of theropod dinosaur. It contains a single known species, Dilophosaurus wetherilli, known from fossil remains found in the Kayenta formation of Arizona.

The first "King of the Dinosaurs", Dilophosaurus is now one of the most famous (Nice job Spielberg). And plus, those crests are just so cool-looking. No frill and poison, those were just imaginary.

It didn't have frills or shoot acid, it was a dangerous dinosaur though and it did have those round horns.

I want to know if this creature had a poisonous spit.

13 Microraptor

While very revolutionary in terms of evolution and paleontology, this guy gets a spot mainly due to it's wings. I mean, who would like a gliding dinosaur?!

14 Tyrannosaurus Tyrannosaurus, meaning "tyrant lizard", from the Ancient Greek tyrannos, "tyrant", and sauros, "lizard" is a genus of coelurosaurian theropod dinosaur. It also had a tremendous bite force, the strongest of any Dinosaur and living terrestrial animal. Its bite force reached up to 12,800 pounds (roughly 5805 Kilograms).
15 Dracorex Dracorex is a dinosaur genus of the family Pachycephalosauridae, from the Late Cretaceous of North America.
16 Suzhousaurus
17 Obamadon
18 Acrocanthosaurus Acrocanthosaurus is a genus of theropod dinosaur that existed in what is now North America during the Aptian and early Albian stages of the Early Cretaceous.
19 Balaur bondoc

This dino came from Romania (my homeland) and was a raptor bigger then the velociraptor. It was weird because it had TWO killing claws on bothe feet so this thing was killer and its name means dragon.this is my favorite raptor

20 Any Ceratopsian

I mean, they have so many weird frills and intricate designs, it's just so hard to choose from which one. We've got Styracosaurus, Pachyrhinosaurus, Medusaceratops and quite a lot of more! So, I just thought if I could just compile all of them into one spot. My personal favorite would have to be Diabloceratops though...

Even if styracosaurus may look weird it is
Still cool and actually a lot of people like it
Like me. Styracosaurus is so cool
And my most favorite dinosaur ever

21 Any Lambeosaurinae

Just too difficult to choose which one. There's just too many to choose from (Parasaurolohpus, Corythosaurus, Lambeosaurus, Tsintaosaurus). Just like No. 9, I thought it was better if I could just but them into one list. Parasaurolophus would be my favorite, it's crest is just way too nostalgic...

22 Scansoriopteryx
23 Parksosaurus
24 Utahraptor Utahraptor is a genus of theropod dinosaurs. It contains a single species, Utahraptor ostrommaysorum, which is the largest known member of the family Dromaeosauridae.
25 Baryonyx Baryonyx is a genus of theropod dinosaur which lived in the Barremian stage of the early Cretaceous Period, about 130–125 million years ago.
