Top 10 Biggest Carnivorous Dinosaurs Ever

1. Spinosaurus

The largest dinosaur on this list and the only one to have spent more than half its time in the water, Spinosaurus measured 50 feet in length and is believed to have weighed up to a massive 22 tons– roughly equal to the anchor of a cruise ship. First described by paleontologist extraordinaire Ernst Stromer in 1915, Spinosaurus (“spined lizard”) had 7-foot-long spines that grew out of its back, forming a fin. Researchers also believe Spinosaurus was the first dinosaur that could swim, spending more time in the water than on land. While prowling the North African swamps 97 million years ago, the dinosaur survived on a diet of fish that it chomped up in its long, razor-toothed snout.

2.Carcharodontosaurus saharicus

Carcharodontosaurus saharicus was a genus of large Theropod that lived in the Late Cretaceous in Africa and grew to be about 39–44 feet long, about 11.5-13 feet tall at the hips and about 6.5 – 8 tonnes (7.2-8.8 tons) in weight. It was among the largest theropods, longer than Tyrannosaurus rex but not quite as big as Spinosaurus.

3. Tyrannosaurus Rex

In 1991, researchers in Canada discovered the bones of the largest T. Rex ever. Dubbed “Scotty,” the specimen is calculated to have weighed nearly 10 tons and measured 42 feet in length. Scotty lived 66 million years ago on Canada’s then-subtropical coast and bore a broken rib, infected jaw, and a bite from another T. Rex on its tail. Perhaps the most famous dinosaur of all time, T. Rex’s place on this list has often been disputed by researchers, with some believing the dinosaur to be the largest of all time.

4. Giganotosaurus

According to LiveScience, Giganotosaurus was once thought to be the largest meat-eater of all back when it was first discovered in the mid-’90s, though larger specimens of other dinosaurs have since been found. Weighing in at over 14 tons, the first specimen found in Southern Argentina measured 41 feet from head to tail, with its skull over five feet long. A study from 2001 done with a model suggested that Giganotosaurus couldn’t chase its prey over 31.3 mph or else it would lose its balance, so as long as you’re in your car and not in a school zone when you meet one, you should be fine.

5.Chilantaisaurus tashuikouensis

Chilantaisaurus tashuikouensis was a gigantic carnivore belonging to the Neovenatoridae family of theropod dinosaurs. It was discovered in the Ulansuhai Formation in China and lived during the Late Cretaceous period. This colossus measured up to 40 feet in length, 4 meters (13 feet) tall at the hip, and had a mass of 6 tonnes. Though at first confused with Shaochilong due to superficial similarities, their size disparity soon cleared this mistake and while they both shared an ancestor to theropods like Allosaurus, carcharodontosaurids, and neovenatorids are closely related.

6. Bahariasaurus

First described by famed paleontologist Ernst Stromer in 1934, Bahariasaurus was a four to nine-and-a-half-ton theropod (ancestrally carnivorous dinosaurs with hollow bones and three-toed legs and arms) that prowled the jungles of Africa 95 million years ago. Similar in its general look to the T. Rex, Bahariasaurus could measure up to 16 feet high and 39 feet long, with little spines that cropped up on its head and back. The only bones of the dinosaur (originally found in Egypt) were kept in a Munich museum that was unfortunately destroyed by Allied bombs during World War II. New Baharariasaurus remains have yet to be found.

7. Yangchuanosaurus

There is much evidence that Yangchuanosaurus was a clever predator. Could it indeed plan its actions in advance? For obvious reasons we are not physically capable of verifying the truth, however, it does not rule out creating more or less convincing theories about that predatory dinosaur. The Yangchuanosaurus shangyouensis skull measures 82 cm (2ft 8in), and its total body length is estimated to oscillate around 8 meters (26 ft). The Yangchuanosaurus Magnus dinosaur could measure even more- over 10 meters (33 ft) – the found skull is 111 cm long (3ft 8in).

8. Deinocheirus

Originally, scientists only had a pair of arm bones with big, long claws to learn about Deinocheirus. But in 2014, new material revealed that it had a unique, large hump on its back, supported by its backbones. Now we know that it was a truly bizarre-looking creature, with huge, clawed hands, a beaked head like a duck, and a hump like a camel. It’s about 32feet long.

9. Siats meekerorum

Siats meekerorum, meaning Man-Eating Monster, was the apex predator of the Cenomanian Stage. It was named after a man-eating monster and the Meeker family, who are museum donors. The holotype specimen is found in Utah, Cedar Mountain formation (Mussentuchit Member), which also gave us the well-known Deinonychus. The holotype is also the only known specimen from this genus, described by paleontologist Lindsay E. Zanno in the year 2009. It is one of the largest theropod dinosaurs known from North America. It was initially classified as a maniraptoran, a group with controversial relations. The group may be tyrannosauroids, allosauroids, or basal coelurosaurs. lt is accepted that the first found specimen was over 9 meters (29ft 6in) long and could weigh over 4tons.

10. Torvosaurus

One of the biggest fields of study regarding Torvosaurus is its supposed size and possible claim to being the largest known Jurassic era theropod dinosaur. ‬Though known from only partial remains, ‬fossils from the Morrison Formation have been compared to other better-preserved theropod genera of the time to yield estimates of around nine meters long. ‬However further fossil material, ‬namely a maxilla(‬upper jaw bone) ‬has been found to be larger than equivalent remains in North America, ‬and when the North American remains are scaled up for comparison a new estimate of up to eleven meters long come to light. It is about 29ft in length.
