Top 10 Unique Dinosaurs

In my opinion, this list of dinos are one of the coolest and strangest dinosaurs ever to inhabit Earth. From a poisonous bite to a ridiculous mating call, every one of the dinos on this list are unique in their very own way. - RaptorOnfRie1206

The Top Ten

1 Therizinosaurus Cheloniformis

My favorite

No other dinosaur like this (tell me if I am wrong)

Therizinosaurus holds the record for the largest claw ever found from any dinosaur. With claws at almost 4 feet long, none but the bravest dinosaurs dared attack the Asian sword-bearer. At 33 feet long, it was large enough to drive away the largest predators of its time and place, such as the tyrannosaurs Tarbosaurus and Alectrosaurus and the oviraptorid Gigantoraptor (watch A Walking With Dinosaurs Special: The Giant Claw, for more information). - RaptorOnFire1206 - RaptorOnFire1206

2 Sinornithosaurus Millenii

Sinornithosaurus Millenii is one of the first dinosaurs that had the ability of flight, and the first dino discovered with a poisonous bite (watch Planet Dinosaur, Episode 2: Feathered Dragons, for more information). At only 3-4 feet long, this tiny imp didn't look like a big threat. But, jumping off the trees of prehistoric China, one bite of the stealthy Sinornithosaurus had enough poison to kill a small herbivore within the hour. - RaptorOnFire1206 - RaptorOnFire1206

Guys! Watch Planet Dinosaur, Episode 2: Feathered Dragons! The Sinornithosaurus scene is awesome! - RaptorOnFire1206

Most awesome dinosaur

Sinornithosaurus's poison is similar to a Gila Monster's, recently discovered by today's technology. :P - RaptorOnFire1206

3 Spinosaurus Aegyptiacus

Spinosaurus! The T-Rex-chasing villain of Jurassic Park III, Spinosaurus isn't THAT powerful, and might overpower Tyrannosaurus in a 1-1 fight, though Spinosaurus would probably die soon after from the T-Rex's bacteria coursing through its veins. At 60 feet long and 20 feet tall, Spinosaurus is the largest land carnivore ever to be discovered. Though its long, weak jaws were probably suited for fishing, not crushing bone such as T-Rex's, Spinosaurus's huge arms were its real weapon, with enough force from its claws to smash through solid steel. Spinosaurus also has an unique "sail" on its back, stretching up to 6 (some scientists estimate 7-8) feet tall, as tall as a full-grown man. The sail was probably used for warming up Spinosaurus when cold. It is also possibly used for attracting mates. - RaptorOnFire1206 - RaptorOnFire1206

4 Gigantoraptor Erlianensis

An overgrown chicken.

Gigantoraptor was one of the first oviraptorids that grew to a gigantic size. At as long and as tall as an Allosaurus Europaeus (a smaller specimen of Allosaurus), the 29-foot-long killer had a beak as powerful as a terror bird's, and large and scary enough to drive away smaller tyrannosaurs such as the 20-foot-long Alectrosaurus (watch Planet Dinosaur, Episode 6: The Great Survivors, for more information). - RaptorOnFire1206 - RaptorOnFire1206

5 Megaraptor Namunhuaiquii

Megaraptor holds the record for the largest claw found from any carnivorous dinosaur, at about 20 inches long. Though Therizinosaurus holds the record for the largest claw found from any dinosaur, the claw wasn't from a carnivore, but an insectivore, which meant Therizinosaurus probably used its claws for defense, unlike Megaraptor's offensive claws, used for ripping apart prey. Though Megaraptor isn't really a big carnosaur, at only about 25-30 feet long and 10 feet tall, its killer claws tell the real story. - RaptorOnFire1206 - RaptorOnFire1206

6 Tyrannosaurus Rex 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 more.

This thing isn't even CLOSE to being unique. It's the same as all other theropods. - Mooshry

Yes! It's the famous "tyrant king", star of the unrealistic but cool film series Jurassic Park! If you think the man-eating car-chasing T-Rex from JP isn't scary enough, I have another secret to tell about this 43-foot-long killer: Tyrannosaurus's bites were supposedly "poisonous". Well, not "poisonous", as in injecting venom into a victim's blood vessels, but rotted flesh, stuck in T-Rex's teeth after its last meal, flowing into the veins of the victim, the bacteria flowing through the bloodlines, slowly breaking down the victim's heart system. So if the 7-ton bite force doesn't kill the prey in one bite, the bacteria will slowly consume the helpless victim as the Triceratops drives T-Rex away with man-sized horns. - RaptorOnFire1206 - RaptorOnFire1206

I can pronounce this one.

7 Amphicoelias Fragillimus

Amphicoelias is the largest animal ever to walk the Earth, and obviously the largest dinosaur ever found. At a massive 190-200 feet long, two times longer than the largest animal alive today, the Blue Whale. This diplodocid weighed over 130 tons, shaking the Earth with every enormous step. With no fear of anything, it holds the record of the largest animal ever to appear on the face of Planet Earth. - RaptorOnFire1206 - RaptorOnFire1206

8 Ankylosaurus Magniventris

At 30 feet long and 7 feet tall, Ankylosaurus is the actual living tank. With enough bony armor to stop a bullet, Ankylosaurus's armor protected itself against killers such as T-Rex and Dromaeosaurus of the time. Even T-Rex's bacteria-full bite wouldn't do any damage: The teeth couldn't even cut through Ankylosaurus's flesh! Ankylosaurus also had a gigantic club at the end of its tail, so strong it could break bone. - RaptorOnFire1206 - RaptorOnFire1206

9 Utahraptor Ostrommaysorum

The largest "raptor"/dromeosaurid ever discovered, this unique killer has a very interesting edge on its side. The largest Utahraptor found was 23.5 feet long in length and 8 feet tall at the head. That made this raptor about the size of a small allosaurid, though most raptors only are about as long as a human and as tall as a child. But recent studies were even more amazing. In the last decade, scientists have studied the bones of Utahraptor and presumably discovered that the fossil(s) found were those of a juvenile's. A full-grown Utahraptor, as some paleontologists predict, had to be at least 36 feet long and 16 feet tall in total. That is just slightly less than the average size of a full-grown Allosaurus! - RaptorOnFire1206 - RaptorOnFire1206

10 Nyctosaurus Nyctosaurus is a genus of pterodactyloid pterosaur, the remains of which have been found in the Niobrara Formation of the mid-western United States, which, during the late Cretaceous Period, was covered in an extensive shallow sea.

A pterosaur with a antler crest that lived near coast and spent most of it's time flying. Nyctosaurus in movies- Thunderclap from The Good Dinosaur. Not a dinosaur but still unique.

Thunderclap! The Good Dinosaur.

The Contenders

11 Bruhathkayosaurus Matleyi

Though Amphicoelias holds the record for the longest dinosaur, Bruhathkayosaurus is obviously the heaviest. The monster is almost 150 feet long, about 40 feet shorter than Amphicoelias, but it weighed more than 220 tons, almost double the weight of Amphicoelias. You don't wanna get stepped on by this gentle but gigantic sauropod. I bet this "gentle giant"'s footsteps could make craters as high as a RV is long! - RaptorOnFire1206 - RaptorOnFire1206

12 Microraptor Zhaoianus

Watch Planet Dinosaur, Episode 2: Feathered Dinos, for more information about Microraptor and Sinorthosaurus! - RaptorOnFire1206

Micoraptor! The smallest dinosaur ever found, this specimen (Microraptor Zhaoianus) is the smallest specimen of the smallest dinosaur found. Whew! Microraptor Gui, a larger specimen of Microraptor, is 3.3 feet long and nearly one-and-a-half foot tall. Another specimen, mid-sized, Microraptor Hanqingi, was 2.7 feet long and about one foot tall. This specimen, the smallest specimen, Microraptor Zhaoianus, is a mere 1.3 feet long and half-a-foot tall. Preyed upon by the other Chinese flying raptor, Sinorthosaurus, Microraptor was a better flyer than Sinorthosaurus, though Sinorthosaurus, the largest specimen at 7.7 feet long and the smallest at 2.2 feet long, could easily take down a Microraptor Gui with it's poisonous bite. But, with its perfection at flight, Microraptor could escape even the most agile and deadly Sinorthosaurus there is! - RaptorOnFire1206

13 Saltasaurus
14 Troodon Inequalis

This tiny, deadly sickle-clawed raptor isn't known for its size or ferocity: It is known for its smarts. Possibly the smartest dinosaur of all (though some paleontologists say Utahraptor was the smartest dinosaur), Troodon could literally outfox a crow. Smarter than the door-knob-turning Velociraptor of Jurassic Park, Troodon is a 5-foot-long, 1.5-foot-tall, Dinosaur Genius. - RaptorOnFire1206

15 Dreadnoughtus Schrani

Used-to-be heaviest dinosaur before the recent discovery of Bruhathkayosaurus, scientists are still arguing about whom should be the heaviest. The only Dreadnoughtus skeleton found was only about 90 feet long and 50 tons heavy, but the specimen found was only a juvenile. The estimates for a full-grown are 130-150 feet long and 210 to 250 tons heavy. The Bruhathkayosaurus weighs 150 feet long and 220 tons heavy. If the full-grown Dreadnoughtus weighs in the 220+ tons area, then Bruhathkayosaurus would be knocked away. But if Dreadnoughtus is under 210 tons heavy at full-growth, Bruhathkayosaurus would keep the record in its hands (or feet). - RaptorOnFire1206

16 Dakotaraptor Steini Dakotaraptor is a genus of large carnivorous theropod dromaeosaurid dinosaur from the Late Cretaceous of North America.
17 Oxalaia Quilombensis
18 Stegosaurus Armatus Stegosaurus is a type of armored dinosaur. Their fossil bones have been found in rocks dated to the Late Jurassic period, between 155 and 150 million years ago, in the western United States and Portugal.

Stegosaurus! One of, probably the, most famous herbivorous dinosaur of all time (even featured in the comedy stickman series, asdfmovie 1-10, as the dinosaur that steps on a guy when he enters the Jurassic Period through a time machine. Though it says the dino is a stegosaur, in the series it looks more like a short-necked Brontosaurus). What makes it so special if not because of the famous part? It, as popularily known, has huge, red, "plates", running down the dinosaur's back in pairs. Though many suggest it uses it as defense, new research shows that the plates could flush red with blood, so it could be used to attract mates or scare away large predators such as Allosaurus. Also, you can't miss the deadly part! The four-spiked tail at its end could stab through light steel, as well as cut through bone. Don't attack a stegosaur... Unless you excel at dodge ball, for that instance. - RaptorOnFire1206 - RaptorOnFire1206

19 Cryolophosaurus Ellioti
20 Shamosaurus

Don't be ashamed, we are all beautiful in our own ways

No face no case

Big Crest Bigger than Two feet

21 Balaur Bondoc

Think of a little smaller velociraptor with two demon claws on each of it's feet instead of one. Awesome little guy.

THIS thing is a wierdo!

22 Concavenator

When it comes to strange dinos this wins. It is a large carnivore with a hump which is weirder then a sail in my opinion

23 Plesiosaurs

We love this swimming pleasant dinosaur. Hoorah - airbb

24 Sauroposeidon Proteles

Though Amphicoelias and Bruhathkayosaurus get all the fame for being the longest and the heaviest, you can't miss the tallest! Every young child recognizes the famous Brachiosaurus as the tallest of all dinosaurs... Wrong! Brachiosaurus is an amazing 75 feet tall... Taller than the 50-foot-tall longest dino, Amphicoelias! But wait... SAUROPOSEIDON is 90 feet tall! And at 125 feet long, the only predator at its time that was brave enough to attack a full-grown Sauroposeidon is the T-Rex-sized carnosaur Acrocanthosaurus Atokensis, whom is more than capable of taking down Sauroposeidon if it hunted in packs. - RaptorOnFire1206

25 Triceratops Triceratops is a genus of herbivorous ceratopsid dinosaur that first appeared during the late Maastrichtian stage of the late Cretaceous period, about 68 million years ago in what is now North America.
26 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.
27 Amargasaurus
28 Shunosaurus
29 Irritator
30 Ouranosaurus

The only iguanodont with a sail and also the only herbivore with one.

31 Parvicursor

Smallest dinosaur in the world!

32 Iguanodon Iguanodon is a genus of ornithopod dinosaur that existed roughly halfway between the first of the swift bipedal hypsilophodontids of the mid-Jurassic and the duck-billed dinosaurs of the late Cretaceous.
