Saltopus (SALT-oh-pus) was a very small bipedal dinosaur that lived in the Norian Age during the Late Triassic Period, around 221 – 210 million years ago, in what is now Lossiemouth, Scotland, UK. The Earth was considerably warmer than it is now at that time. Saltopus has been variously identified as a saurischian (lizard-hipped) dinosaur, a more advanced theropod, and a close relative of the herrerasaurs, but its taxonomy is in dispute because only fragmentary remains have been recovered. Other Herrerasauria members include Herrerasaurus, Staurikosaurus, Eoraptor and other very early dinosaurs. Saltopus was one of the first dinosaurs to roam the Earth.

Saltopus measured around 2 feet (0.7 metres) in length, about the size of a rabbit or small cat and weighed only 1 kilogram (2 pounds). It was lightly built and had hollow bones like those of modern birds. Saltopus had thin long legs with clawed toes and short fore limbs with 5 fingers on each hand, the 4th and 5th digits being very small, that were also probably clawed. Its head was elongated and it had many sharp teeth. Saltopus could run very fast and its short stiff tail would have helped it to change direction quickly. Scientists think Saltopus may have even been able to jump. Dinosaur speeds are estimated using their like leg length and estimated body mass and fossilized trackways.

Sauroposeidon (Sore-owe-pos-eye-don) is a genus of sauropod dinosaur that lived in the Aptian and Albian epochs during the Late Cretaceous period around 112 – 110 million years ago on the shores of the Gulf of Mexico, the River Delta, which ran through Oklahoma at that time. Its relatives include another huge sauropod dinosaur, Brachiosaurus. Other dinosaurs that livedat the same time were the carnivorous Deinonychus, the armoured herbivores Sauropelta and Nodosaurus, and the sail-backed carnivore Acrocanthosaurus.

Sauroposeidon was a huge dinosaur and measured 112 feet (34 metres) in length, 56 feet (17 metres) in height and weighed a massive 66 tons. It was probably the tallest, longest and heaviest dinosaur ever to walk the Earth beating even the enormous dinosaur Mamenchisaurus. It is thought that when Sauroposeidon walked, it shook the Earth. Sauroposeidon had a short, bulky body and would have stood 23 feet (7 metres) at shoulder height.

Sauroposeidon was a quadrupedal dinosaur that walked on its 4 thick, trunk-like legs. Its fore limbs were longer than its hind limbs and it had a similar body shape to modern day giraffes.

Saurornitholestes (Saw-roar-nith-owe-less-teez) is a genus of dromaeosaurid dinosaur that lived in the Upper Campanian Stage during the Upper Cretaceous period around 75 million years ago in Alberta, Canada, North America. Other dromaeosaurids include the Velociraptor and Dromaeosaurus.

Saurornitholestes was a small, bipedal dinosaur who measured 6 feet (2 metres) in length and weighed 12 kilograms (30 pounds). Like other theropods in the family Dromaeosauridae, Saurornitholestes had a long, curved, blade-like claw on the second toe. It was similar to the Velociraptor as it had large sharp, fang-like teeth in the front of its jaws. Saurornitholestes was lightly built and had long legs and a beak. Some believe that Saurornitholestes may have been covered in feathers. This dinosaur had a relatively large brain.

Saurornitholestes was a carnivore and was perhaps a scavenger who fed up on carrion and small animals and reptiles such as lizards, frogs and early birds.

Shunosaurus measured 40 feet (11 metres) in length and weighed around 19 tons. It is the only sauropod known that had a bony club at the end of its tail, formed by enlarged vertebrae. This small tail club had two small spines on it and was probably used for defence to swipe away predators.

Shunosaurus was a quadrupedal dinosaur and walked on all 4 of its trunk-like legs. Its body was huge and bulky and it had a long neck, a long tail and a short deep skull. Its front and hind legs were similar in length, making its back relatively level with the ground.

Shunosaurus was a herbivore and ate plant material. It would have had to eat a huge amount to sustain its large size, although it was not as huge as other giants such as Argentinosaurus and Diplodocus.

Spinosaurus was instantly recognisable with a beautiful sail that went down the length of its back. Brightly coloured to attract mates or frighten its rivals, Spinosaurus was a beautiful but also a highly effective predator.

Spinosaurus was from a family of dinosaurs called Spinosaurids. This unusual family of dinosaurs all had tall spines or sails along their backs and included the terrifying Spinosaurus.

Spinosaurus was a Theropod, carnivorous, and as it lived comfortably on both land and water scientists believe it would have eaten both water and land prey. Spinosaurus was such a large predator it would have been able to tackle anything it wanted. However, scientists believe that Spinosaurus would have eaten more aquatic prey. Around 110 million years ago there would have been giant sea turtles, large fish such as the Mawsonia and perhaps even small plesiosaurs.

Spinosaurus lived in North Africa, with bones of this dinosaur found in Egypt and Niger. Spinosaurus lived around 110 million years ago in the Cretaceous period.

Stegosaurus (steg-oh-saw-rus) from Greek stegos (στέγος), which means roof, and sauros (σαῦρος), which means lizard – is without doubt one of the most recognisable dinosaurs.

With its beautiful and rather large plates along its back make it instantly recognisable all over the world. 

Stegosaurus is the largest and most famous member of the stegosaur family and would have been an incredible sight to see roaming the open plains of what is now North America in the late Jurassic Period 150 million years ago.

The types of plants that were around at the time include cycads, ferns and horsetails were Stegosaurus’ diet. Stegosaurus may have also eaten the occasional conifer tree saplings, but we’ll never be 100% sure.

Unfortunately, Stegosaurus wasn’t the smartest dinosaur in the world. Stegosaurus probably had the smallest brain out of any dinosaur that’s ever been discovered. Stegosaurus’ brain was around five centimetres long which is roughly the size of a walnut. Experts are still really puzzled as to why such a large animal had such a small brain.

Stegosaurus had incredibly strong back legs, which were nearly twice as long as its front legs. Its flat feet had three big toes and one tiny one designed for carrying weight. Stegosaurus was not built for speed and was probably comparable to a modern day an armoured tank, slow but very powerful.

Styracosaurus (sty-RACK-oh-SAWR-us) was a genus of ceratopsian dinosaur who lived in the Campanian stage during the Cretaceous Period, around 76 to 75 million years ago. Styracosaurus lived in Alberta, Arizona, Montana, North America.

Styracosaurus measured 18 feet (5.5 metres) in length, 6 feet (1.8 metres) in height and weighed around 3 tons. It had 6 horns extending from a neck frill and a smaller horn above each of its eyes. Their skull was massive, with a large nostril and a tall straight nose horn. Each of the 4 longest frill spines was comparable in length to the nose horn, at 50 to 55 centimetres long.

Styracosaurus was quadrupedal and had 4 short, thick legs, a thick, pointed tail and a powerful body and shoulders. Like most ceratopsids, Styracosaurus had large fenestrae (skull openings) in its frill. The front of the mouth had a toothless beak.

Supersaurus (super-SAW-rus) was a sauropod dinosaur that lived in the Kimmeridgian – Tithonian stages during the Jurassic period, around 155 – 145 million years ago, in Colorado. USA. Supersaurus is very closely related to Apatosaurus. Jurassic was a time of huge sauropods including Diplodocus, Camarasaurus, Apatosaurus and Brachiosaurus. Also around at that time was Stegosaurus and the fierce carnivore, Allosaurus.

Supersaurus measured 131 feet (40 metres) in length, 54 feet (16.5 metres) in height and weighed 55 tons. It had a very long neck that measured 39 feet (12 metres) long and a small head. It may have had very limited vertical neck mobility. Supersaurus held its neck more or less parallel to the ground. Its long neck would have been useful for foraging in trees in forests where it would not otherwise be able to venture because of its great size.

Supersaurus was a herbivore and would have used its spoon-like teeth to strip foliage and grind up prehistoric plant material such as conifers, gingkos, cycads and ferns. It would have eaten a huge amount of vegetation to sustain its huge size and may have swallowed gastroliths (stomach stones) to help with the digestion of tough plant material.
