Abelisaurus skull fossil

We start our list of dinosaurs with Abelisaurus, a predatory theropod dinosaur of the late Cretaceous Period. Abelisaurus was a medium-sized, bipedal* dinosaur that was probably between 7 and 9 metres (23 and 29 ft.) in length.

* An animal is said to be ‘bipedal’ if it walks on two legs.

Everything that we know about Abelisaurus comes from a single, incomplete skull! From this fossil scientists have been able to deduce the dinosaur’s likely lifestyle, diet and size.

Being able to piece together a picture of how dinosaurs lived from the limited clues available to us is an important part of paleontology. (Paleontology, or palaeontology in British English, is the scientific study of prehistoric life. )


List Of Dinosaurs Albertosaurus
List Of Dinosaurs: Albertosaurus. Click image for more info.

Albertosaurus was a close relation of Tyrannosaurus, and was in the same family, Tyrannosauridae. Looking very much like its more famous relative, Albertosaurus walked on two legs, and had small arms. It would have been a fast runner, and probably sat at the very top of the food chain.

Albertosaurus had crests above its eyes which may have been brightly coloured. Unlike Tyrannosaurus, whose eyes pointed forwards, its eyes were on the sides of its head.


Allosaurus was a large carnivorous dinosaur from the Jurassic period. Click the picture to find out more!

Allosaurus was one of the largest predators of the Jurassic Period. It would have reached lengths of around 12 metres (40 ft.), and weighed between 2 and 5 metric tonnes (2.2 and 3.3 short tons).

Allosaurus preyed on dinosaurs such as Stegosaurus, and may even have hunted huge Jurassic Sauropods such as Diplodocus and Apatosaurus.


dinosaur names and pictures ankylosaurus
Ankylosaurus: click the image for facts about this dino.

Ankylosaurus was a member of a group of dinosaurs called Ankylosauria. Their name means ‘fused together lizards’ on behalf of their joined-together armoured plates.

Ankylosaurians were members of a larger group of dinosaurs called Thyreophora, otherwise known as the ‘shield-bearers’, or ‘armored dinosaurs’. This group also included Stegosaurians such as stegosaurus.

Ankylosaurus was around 10 metres (33 ft.) in length and weighed around 5 metric tonnes (5.5 short tons). It had a bony club at the end of its powerful tail. This would have been an effective weapon against predators.


Apatosaurus was one of the biggest land animals ever to walk the earth.

Apatosaurus was a huge sauropod dinosaur. It lived in the late Jurassic Period. It weighed between 20 and 30 metric tonnes (22 and 33 short tons), and was around 20 to 23 metres (65 and 75 ft.) in length.

Apatosaurus achieved its colossal size by eating plants rather than meat. It may have used its long tail as a whip to protect itself from predators.

Brontosaurus was discovered after Apatosaurus. At the time it was thought to be a different dinosaur, but it was later found to be an Apatosaurus. However, the name ‘Brontosaurus’ had become so widely-used that many people still think that they are different dinosaurs.

There’s a twist in the tail: recent studies have found that the Brontosaurus may not be an Apatosaurus after all!


Archaeopteryx. Click picture for more information.

If you can imagine a cross between a small dinosaur and a bird, then you’ll probably have a good idea of what Archaeopteryx looked like. It had the tooth-filled mouth and bony tail of a dinosaur, with the feathered wings of a bird. It may even have been able to fly, rather than simply glide.

Archaeopteryx lived in the late Jurassic Period. Animals like archaeopteryx (but possibly not archaeopteryx itself) were the ancestors of all today’s birds. Many scientists now consider birds to be dinosaurs!


baryonyx walkeri

Baryonyx was a two-legged, fish-eating dinosaur that lived in the early Cretaceous Period.

In 1983, amateur fossil collector William J. Walker came across a strange fossil. He alerted the Natural History Museum in London, who realised that he had made an important find.

After further digging, palaeontologists uncovered around three-quarters of a new dinosaur. It was named Baryonyx walkeri, in honour of its discoverer.


Brachiosaurus: Click on the photo for more information

This huge sauropod grew up to 25 metres (82 ft.) in length and weighed between 30 and 50 metric tonnes (33 and 55 short tons). It was one of the largest land animals ever. Brachiosaurus’s name means ‘arm lizard’, because of the way its forelimbs joined its shoulders.

Unlike other sauropods, Brachiosaurus’s front legs were longer than its hind legs.


(See Apatosaurus)



Carnotaurus was a large, fast-moving predator that walked on two legs. It was around 9 metres (30 ft.) in length, and weighed around 1.35 metric tonnes (1.5 short tons).

This distinctive meat-eater had two horns on its head. Its name means ‘meat-eating bull’ on behalf of these bull-like horns.

Coelophysis is one of the earliest known dinosaurs. It lived in the late Triassic Period. Despite their great age, many Coelophysis fossils have been found.

Coelophysis was a small and lightly-built dinosaur. It would have been nimble and fast, and may have hunted in packs.


Compsognathus. Image by Nobu Tamura ( [CC BY 2.5]
Only two Compsognathus specimens have been discovered. The first was found in Germany in the mid-nineteenth century. The second was found in France over 100 years later, in 1971.

Compsognathus lived during the late Jurassic period.

This bird-like bipedal predator was famous for many years for being one of the smallest dinosaurs. Since the end of the twentieth century, however, several smaller dinosaurs have been discovered.


List Of Dinosaurs Deinonychus
List Of Dinosaurs: Deinonychus

This early Cretaceous dinosaur grew to around 3 metres (10 ft.) in length and weighed around 80 kg (176 lb). Its name, which means ‘terrible claw’, refers to the deadly claw found on each of its feet.

While small compared to other dinosaurs, Deinonychus was built for speed, and would have been an effective predator. It had long forelimbs and powerful clawed ‘hands’.



Diplodocus, like all other sauropods, was a giant, four-legged dinosaur with a long neck and tail. It may have used its long tail as a whip for protection against predators.

Diplodocus was around 25 metres (82 ft.) in length. It weighed between 10 and 26 metric tonnes (11 and 29 short tons). It lived in North America during the late Jurassic Period.


Edmontosaurus. Image by Nobu Tamura ( [CC-BY-SA-3.0]
Edmontosaurus was a large herbivorous dinosaur. It was a member of the ‘duck-billed’ group of dinosaurs, so-called due to their duck-like mouths. Herds of edmontosaurus roamed western North America in the late Cretaceous Period.

Edmontosaurus would have walked on its longer hind legs for most of the time. By studying its teeth, paleontologists can tell it was a grazer. While grazing it would probably have walked on all four legs.


Giganotosaurus List of Dinosaurs
List of Dinosaurs: Giganotosaurus

Giganotosaurus means ‘giant southern lizard’. This giant predator walked on two legs and was even bigger than Tyrannosaurus.

Giganotosaurus was around 16 metres (62 ft.) in length and weighed 8 metric tonnes (9 short tons). It was likely to have had good senses of both sight and smell.

Giganotosaurus was found in South America during the late Cretaceous Period.


Gorgosaurus. Image by Johnson Mortimer [CC BY 3.0]
With a huge skull and jaws filled with sharp teeth, Gorgosaurus definitely lived up to its name, which means ‘dreadful lizard’.

Gorgosaurus was a close relative of tyrannosaurus, being in the same family, Tyrannosauridae. Gorgosaurus lived in the late Cretaceous Period and was found in America and Canada.


Iguanodon feeding by lake
Iguanodon: click image for more information about this dinosaur.

Iguanodon was the second dinosaur ever to be named. The first Iguanodon fossil was a tooth. It was discovered in England by the wife of medical doctor and geologist Dr Gideon Mantell. Mantell named the specimen Iguanodon, because the tooth resembled that of an iguana.

Iguanodon was a large, plant-eating dinosaur, able to walk on two and four legs. It lived in the early Cretaceous Period.

Iguanodon had spiked thumbs. These may have been used either as a means of defence against predators or for fighting with other Iguanodons.


Leaellynasaura. Image by Danny Cicchetti [CC BY-SA 3.0] Click to enlarge image.
This small bipedal dinosaur was just under 1 metre (3 ft.) in length. It was first discovered in the Australian dinosaur hotspot Dinosaur Cove.

Leaellynasaura lived in the early Cretaceous Period. It may have been fully-feathered.


Megalosaurus: click image for more info about this dino.

Megalosaurus was discovered in England. It was the first dinosaur to be named. Surgeon and geologist James Parkinson identified some fossilised remains as being those of a reptile. He named it ‘Megalosaurus’, which means ‘great lizard’. This was in 1824: almost twenty years before Sir Richard Owen invented the word ‘dinosaur’!

Megalosaurus was around 9 metres (30 ft.) in length and weighed around 1 metric tonne (1.1 short tons). It stood on two legs, and was a predator. It lived in the middle Jurassic Period.


Minmi. Click to enlarge image.

Minmi was a heavily armoured small dinosaur of the Ankylosauria family. Its body, including its undersides, was covered with bony plates. It had longer legs than most of its relatives, suggesting that, despite being heavily armoured, it could move quickly.

Minmi fossils have been discovered in Australia. It lived in the early Cretaceous Period.


Ornithomimus. Image by Tom Parker [CC BY-SA 4.0]
Ornithomimus was an ostrich-like dinosaur. Around 3.5 metres (11.5 ft.) long, Ornithomimus had long legs and a long, thin neck. It would have been able to run at high speeds, possibly reaching over 40 mph (64 km/h).

Ornithomimus means ‘bird mimic’. It is so-named due to its bird-like feet. Fossils suggesting Ornithomimus had feathers have been found.


Parasaurolophus. Click image for more information.

Parasaurolophus was a Late Cretaceous herbivore. It was around 10 metres (33 ft.) in length and weighed around 3.5 metric tonnes (4 short tons).

Parasaurolophus had a distinctive crest at the back of its head. Tubes inside of this crest were connected to its nostrils.Scientists speculate that this arrangement may have been used to produce sound.

Parasaurolophus had a tall but narrow tail. Males may have had brightly-colored tails in order to attract females.


Protoceratops andrewsi

Protoceratops was a sheep-sized dinosaur of the late Cretaceous Period. It had jaws shaped like a parrot’s bill, and a mouthful of teeth for eating tough vegetation. A frill on the back of its head may have served to protect its neck.

In Mongolia, a fossilised protoceratops was found entwined with a fossilised velociraptor. The velociraptor may have been attacking the protoceratops before a land slip buried both animals.


spinosaurus dinosaur
Spinosaurus. Click the photo to find out more.

Spinosaurus was a meat-eating dinosaur of the late Cretaceous Period. Growing up to 15 metres (49 ft.) in length and 23 metric tonnes (25.35 short tons) in weight, it was larger than the mighty Tyrannosaurus Rex.

Spinosaurus was quite possibly the largest predator ever to have walked the earth.

Spinosaurus means ‘thorn lizard’ or ‘spine lizard’. The name comes from Spinosaurus’s most distinctive feature: a large ‘sail’ on its back, which consisted of spines covered by a layer of skin.

Scientists think that this bony sail helped spinosaurus to warm up faster than other dinosaurs, allowing it to hunt when others could not.


Stegoceras. Click image to enlarge.

Stegoceras was a bipedal herbivore that lived in North America during the late Cretaceous Period. It was around 2 metres (6.5 ft.) in length and stood around .75m (2.5 ft.) tall.

Stegoceras was a Pachycephalosaurian; a ‘dome-headed dinosaur’ with a very thick skull. It was probably a herd animal.


Stegosaurus/ Click image to find out more about this dinosaur.

Stegosaurus was a large plant-eating dinosaur in the Stegosauridae family. It roamed America during the late Jurassic period.

Stegosaurus grew to around 9 metres (30 ft.) in length, and weighed around 2 metric tonnes (2.2 short tons). This large dinosaur was no rocket scientist; its brain was around the size of a walnut!

Stegosaurus had a row of large bony plates running along the top of its back. There are various explanations as to what the plates were for. Some scientists think that they offered protection from predators, others believe that they helped the animal stay at the correct temperature.

Stegosaurus was able to defend itself with a cluster of spikes on its tail.


Suchomimus. Image by ДиБгд [CC0]. Click image to enlarge.
Suchomimus was a member of the Spinosauridae family of dinosaurs, and a relative of Spinosaurus.

Like Spinosaurus, Suchomimus had a spiny sail on its back and a long, crocodile-like face. It lived in Africa during the early Cretaceous Period.


Triceratops. Click image to find out more.

Triceratops’ name means ‘three-horned face’. This fearsome-looking herbivore was found in western America during the late Cretaceous Period. It may have lived in herds.

Triceratops was a large, heavily built dinosaur. It would have been able to put up quite a fight if attacked by meat-eaters such as Tyrannosaurus or Albertosaurus.


Troodon dinosaur names with pictures
Dinosaur names with pictures: Troodon. Click image to find out more.

Troodon was a small, bird-like dinosaur of the Late Cretaceous Period. It grew to around 2 metres (6.5 ft.) in length, and would have stood waist-high to a man.

Despite its small size, troodon was well armed. It had sharp teeth, clawed fingers, and an enlarged, sickle-shaped claw on each of its feet. This intelligent dinosaur was fast, agile, and equipped with good eyesight.


tyrannosaurus rex
Dinosaur names with pictures: Tyrannosaurus Rex. Click image for more information on this dinosaur.

Tyrannosaurus is perhaps the most famous type of dinosaur in the world, and no list of dinosaurs would be complete without it! One species in particular, Tyrannosaurus Rex, is particularly well-known as being the archetypal ‘killer dinosaur’.

Tyrannosaurus is one of the largest land-based meat-eaters of all time. Not only was it strong; it was also intelligent, fast, and equipped with excellent senses of both sight and smell.

One feature of tyrannosaurus is its huge skull. The skull would have been able to support large jaw muscles, giving tyrannosaurus a powerful bite.

Tyrannosaurus grew to around 12 metres (40 ft.) in length, and weighed up to 8 metric tonnes (9 short tons). It lived right to the end of the Cretaceous Period, becoming extinct along with all of the other non-bird dinosaurs in the Cretaceous-Paleogene Extinction Event.


Artist’s impression of a velociraptor. In reality, the velociraptor was quite a small dinosaur, and possibly had feathers.

Velociraptor was a small, bird-like, predatory dinosaur of the late Cretaceous Period. Its name–which means ‘swift plunderer’–accurately describes this speedy, fierce carnivore.

Velociraptor was armed with sharp teeth and sharp claws. Its most fearsome weapons were the large, curved inner claws on either foot. These were probably used not only for slashing and ripping, but also to grab and restrain the velociraptor’s unfortunate prey.

In many films, velociraptor is portrayed as being taller than a man. In real-life, however, it would have been waist-high at most. It may also have been fully feathered.

    • Good question,
      Some dinosaurs (e.g. Albertosaurus and T. rex) were “bipedal”, meaning that they walked on their two (hind) legs. Some dinosaurs (e.g. Apatosaurus and Brachiosaurus) were “quadrupedal”, meaning they walked on all four legs, and others (e.g. Edmontosaurus and Iguanodon are thought to have alternated between walking on two and four legs, depending on whether they were walking, running, browsing, grazing, etc.

  1. How are the ichthyosaurs classified? I guess they diverged before the archosaurs evolved, and then the dinosaurs branched off from them. I live in Nevada, and we have a state park devoted to their fossils.

    • Great question!

      The early evolution of the ichthyosaurs is quite cloudy but yes, what you say does seem to be the case.

      The early ancestors of ichthyosaurs probably branched off from other diapsid reptiles in the early Triassic, before the emergence of the archosaurs.

      The dinosaurs then evolved from the archosaur branch (not from the Ichthyosaur branch, which became extinct in the Cretaceous).

      We assume you mean the Berlin-Ichthyosaur State Park? It sounds a fascinating area and we would love to visit it one day!

  2. Fact:
    Stegosaurus pump blood into their plates and it goes different colours and also it is used to scare other predators away.
    Ankylosaurus’ tail can break a T. rex’s bones in 1 swipe

  3. Fact
    The stego pumped blood into the plates on there back and it comes in so many different colours and it is used to scare the apponents away
    The bone on the tail of a ankilosaurus can break a trex’s bone in 1 shot

  4. What about cryolophosaurus I heard about this on dinosaur king plz can give me a description of what it looks like and facts about it thx

  5. others that should be here


  6. You should add stuff like Therizinosaurus and Deinocheirus and Erlikasaurus. You could also add Ostafrikasaurus and Irriator and more.

    • Never heard of
      I am a bit of a Dino nerd I know quite a bit about dinos but not them names thx

    • Great suggestions (we’ve never even heard of #3!). They’re not dinosaurs, so we may add them to a prehistoric animals page in the future.
      Thanks again 🙂

    • Sorry to be that guy but…. In your article of Carnotaurus you say it is the only horned theropod, this is inaccurate. Ceratosaurus was a horned as well. On that note I love that you describe Carnotaurus as being agile and an exceptional hunter. I have read other articles that say the meat eating bull was a slow scavenger. Looking at the skeleton you can definitely tell this creature could run fast and be agile.

      • Hi Chad,

        No need to apologize, we appreciate your comment. You’re quite correct; Ceratosaurus did indeed have horns (the genus name even means ‘horned lizard’). We’ve amended the Carnotaurus page accordingly.

  7. I wonder is there a specific site that has a lot of dinosaurs i have been to zoom it is awesome but i need more I would love to see new ones. i have 7 books but a lot of the dinosaurs are multiple . I heard there were new dinosaurs i am not sure but i think China .i am kind of addicted but i wish some of them would of survived .

  8. Love your animals and facts sheets. Our staff provide 14 supported playgroups across Canterbury Bankstown NSW and teach children and parents about animals and many more topics. Would love your newsletter. Love science and exposing children to a significant area.

    Dom, 15 year old from PA

    • Hi,

      Thank you for your comment, well spotted!

      It’s actually a pterosaur – a flying reptile – rather than a bird.

      The actual species isn’t given. However, judging by the crest we think it may be a member of the family Pteranodontidae, which, like Triceratops, were around in North America in the Late Cretaceous period.

      We hope this helps!
