Paleontologists – fossil scientists – have found that dinosaurs have died from respiratory infections, such as coughing, sneezing, and fever.
In February 2022, palaeontologists documented their evidence that a respiratory infection killed a 15-year-old diplodocid dinosaur.

Scientists have recently documented their findings of the bones of a new species of two-legged dinosaur in Zimbabwe. It is believed to be the oldest ever found in Africa.
The plant-eating dinosaur is the predecessor of the long-necked sauropods. This new species has been named Mbiresaurus raathi.

Did a crocodile eat a dinosaur?
Yes, a crocodile ate a dinosaur. Paleontologists at the Australian Age of Dinosaurs Museum found a crocodile fossil and in its stomach (in its gut) was the remains of a dinosaur. This is very rare because it is the first evidence of a dinosaur predation in Australia – which means that a dinosaur was eaten. The dinosaur was the prey, not the predator. The crocodile was the predator.
Paleontologists are scientists who study fossil animals and plants. Fossils are life forms that existed thousands and millions of years ago.

The Tyrannosaurus (Tyrannosaurus rex) is a large, bipedal, carnivorous theropod dinosaur in the Tyrannosauridae family. Its name means king of tyrants. It is commonly known as Tyrannosaurus Rex or T-Rex.
It lived about 68-66 million years ago in the Upper Cretaceous period.
The Tyrannosaurus had a large head and long, heavy tail. It had powerful hind (back) legs and very small front legs. It is bipedal, which means that is walks on two legs. Its back legs had two clawed digits. Its teeth were long, curved, and crenelated (notched).

The Stegosaurus (Stegosaurus stenops) is a large, four-legged, herbivorous armoured dinosaur in the Stegosauridae family. Its name means roof lizard.
It lived about 155-150 million years ago in the Late Jurassic period.
The Stegosaurus is easily recognizable. It had a small head, short neck, and rounded back. It had large knife-shaped, upright plaques along its back and spikes on its tail. It walked on four legs, with its front legs shorter than its hind (back) legs. It had small, triangular, flat teeth.

The Rhamphorhynchus (Rhamphorhynchus muensteri) is a pterosaur in the Rhamphorhynchidae family of long-tailed pterosaurs in the Jurassic period. Rhamphorhynchus means beak snout. It is a cousin of the dinosaurs, and it is believed to be among the first flying vertebrates.
It had a long tail that ended with a soft tail vane. It had needle-like teeth that were angled forward. It also had a curved, sharp, beak-like tip that lacked teeth. From a study of its teeth and stomach contents, palaeontologists think that its diet was mainly fish and cuttlefish.

The Giraffatitan (Giraffatitan brancai) is a large, four-legged sauropod dinosaur in the Brachiosauridae family. Its name means titanic giraffe. It was found in the country that is now Tanzania in Africa.
It lived about 150 million years ago in the Late Jurassic period.
The Giraffatitan walked on four legs, with its front legs longer than its hind (back) legs. The first toe on its front feet, and the first three toes on its hind feet, were clawed. It had a long neck, like a giraffe’s neck. Its tail was also long. It had spatulate, or chisel-shaped, teeth.
It was a herbivore, because it ate plants.

The Epidexipteryx (Epidexipteryx hui) is a small pterosaur, a cousin of the dinosaur, in the Scansorioptergidae family.
Palaeontologists found a partial skeleton, which was from the Middle Jurassic or Upper Jurassic period.
It had four long tail feathers with central, unbranched rachis (spines) and vanes. Modern birds have branched vanes. It also had simpler body feathers than modern-day birds. It had teeth, but only in the front of the jaw, with long front teeth angled forward.

The Cryolophosaurus (Cryolophosaurus ellioti) is a large well-built theropod dinosaur in the Cryolophosaurus genus. Cryolophosaurus means frozen crested lizard beause it was found in Antarctica (South Pole).
It lived about 180 million years ago in the Early Jurassic period.
The Cryolophosaurus had a high, narrow skull. It had a bony crest just above the eyes. It had long, heavy hind (back) legs and short forelimbs (front limbs), like arms. It had two large clawed digits, and a smaller digit, on each limb. It had a long, thick tail, and a coat of feathers.

The Compsognathus (Compsognathus longipes) is a small, bipedal, carnivorous, theropod dinosaur in the Compsognathidae family. Compsognathus means dainty jaw. Bipedal means that it walks on two legs.
A skeleton was discovered in 1859 in Germany, and also in the south of France.
It lived about 150 million years ago in the Tithonian age of the Late Jurassic period.

The Archaeopteryx (Archaeopteryx lithographica) is a small pterosaur, a cousin of the dinosaur, in the Archaeopterygidae family. Archaeopteryx means ancient wings.
Palaeontologists think it was the oldest known bird that was on the Earth. It lived in the Late Jurassic period around 150 million years ago in the land that it now called Europe.
