Top 10 Most Dangerous Dinosaurs Ever

From Allosaurus to Troodon and Sinosauropteryx to Tyrannosaurus Rex, these were some of the deadliest and most dangerous dinosaurs that ever roamed our planet Earth. Just imagine their powers and abilities of destruction if they were alive today!

10. Sinosauropteryx

This was among the first dinosaurs discovered from the Yixian Formation. They were indigenous of north eastern China and were found there during early Cretaceous period. They belong to the Compsognathidae family. They had short arms and a long tail as shown in the above image. Unlike many other large members in this list of most dangerous dinosaurs, Sinosauropteryx was of small size.

 9. Troodon

Genus name of Troodon is Greek for “wounding tooth,” a reference to the single incisor by which it was originally known. As shown in the image, they were also small dinosaurs (larger than Sinosauropteryx) and in general, had appearance of a bird. They lived in late Cretaceous period. They belong to the Troodontidae family. Their fossils were found in North America and unlike most dinosaurs, Troodon flourished in colder climates. Their body length was up to 2.4 metres (7.9 ft) and had mass of up to 50 kilograms (110 lb).

8. Ankylosaurus

Ankylosaurus belongs to the family of Ankylosauridae and meaning of their name is fused lizard. Being huge armored dinosaurs, their maximum body length was up to nine meter (30 feet), having weight of around 6,000 kilograms (13000 lb). Their time period was also late Cretaceous and they were found in Northern America.

7. Sarcosuchus

These giant size dinosaurs were in fact SuperCrocs i.e. largest crocodiles that ever lived on earth. They belong to the Pholidosauridae family. Their living period can be traced back to around 112 million years ago. These were probably among the largest crocodile-like reptiles that ever lived in the world. Their normal length was 12 meters and they weighed over 8 tonnes. Their fossils were found from Sahara Desert of African continent.

6. Allosaurus

Allosaurus belongs to the Allosauridae family and they were found in around 155 million years ago. Allosaurus means “different Lizards”. Their normal length was 9 meter and according to the one of opinion, they may grow to the maximum length of 12 meters. And they were 2.3 metric tons in weight. Oh my God! such a monstrous creatures they were.

5. Liopleurodon

Liopleurodon belongs to the Pilosauroidea Suborder and this was the mightiest aquatic predator of all time. Their fossils were found in England and France and the longest confirmed Liopleurodon fossils are estimated to have grown up to 25 meters.

4. Kronosaurus

Kronosaurus was a short-necked plesiosaur, a pliosaur. It was a Mesozoic marine reptile and not actually a dinosaur, but they were very large in size. Their fossils were found in Australia and Colombia. The meaning of their name is “Lizard of Kronos”. Their average length was 10 meters. They had large teeth, up to seven centimeters long and which may sometimes grow up to 30 centimeters in length.

3. Amphicoelias Fragillimus

These dinosaurs belong to the Diplodocoidea Superfamily. Their average length was forty to sixty meters and they were 122 metric tons in weight. I guess these are the largest and tallest species of its family. Their fossils were lost so there is no vast information available about them.

2. Velociraptor

These vibrant dinosaurs were found about 75 million years ago. They were as well part of Cretaceous period. They were found in China and Mongolia. They belong to the Dromaeosauridae family. Their average length was two meter and they were up to fifteen kilogram in weight.

1. Tyrannosaurus Rex

They belong to the Tyrannosauridae family. The meaning of their name is “Tyrant Lizard”. Their fossils were found in Western North America.
