Conquering the World with its Spikes: Biber the Stegosaurus

Stegosaurus is a large dinosaur covered by solid protective armor. Biber was an adult male Stegosaurus, 30 feet (9 meters) long, weighed 4 tons and 9 feet tall at its hip. If we count its bone plates, its height could reach 11 feet.

Zhuangzhuang the Huanghetitan: Asia’s Fattest Dinosaur

The Huanghetitan was a large sauropod. Its body can be as long as 49 feet (15 meters) and its toes could reach up to 7.9 inches (20 centimeters). Did such a big body serve some practical purposes? Yes. The Huanghetitan made full use of its body, so that when the Luanchuanraptors attacked en masse with fangs and claws, it could simply knock them away. 

Gamba the Carcharodontosaurus: Biting and Tearing Rapidly

Carcharodontosaurids were a group of relatively large theropod dinosaurs that appeared in the Late Jurassic Period. They lived in many parts of the world. Fossils of Carcharodontosaurus were first discovered in North Africa. Despite the large head, Carcharodontosaurus’s brain was only half the size of a T-rex’s. In other words, Carcharodontosaurus was not as intelligent as the latter.

Even so, in the Early Cretaceous in present-day North Africa, Carcharodontosaurus had almost no rivals. It played its strength to the limit; its large body, sharp teeth, quick bites, strong hind legs, and powerful tail, all helped it to become the top land predator of its habitat.

A reconstruction of a Torvosaurus embryo

The most powerful weapons of Conard the Torvosaurus were its teeth and claws. Its teeth were sharp with serrated edges. These could pierce the flesh and bones of most prey. It had three claws on each forelimb. The keratinous claw on the first digit was as large and sharp as a sickle. Although its forelimb had only a limited swinging range, it could easily pull the prey towards its powerful mouth and prevent it from escaping. When Conard encountered its favorite prey it could deliver a fatal bite while the forelimbs held it firmly. 

In Portugal, scientists discovered a dinosaur nest with dinosaur embryos inside. They concluded these were Torvosaurus’s eggs, judging from one of the their maxillary bones.

Conard the Torvosaurus: King of the Jurassic Period

Do you know which dinosaur was the most powerful predator in the Jurassic period?

Some say Allosaurus. Allosaurus was certainly a capable hunter, but there was a group of little-known but equally powerful dinosaurs – Torvosaurus. They have an average body length of 36 feet (11 meters), even bigger than the largest Allosaurus. Conard, a Torvosaurus, was 36 feet long and weighed about 5 tons. Its sturdy skull could withstand strong impacts from fierce fighting and extreme predation with no injury.

An-an the Beibeilong : The Biggest Hatchling Dinosaur

What is it?

Paleontologists have been wondering since the fossils were found in Henan, China, in 1991. Since no answer was available at the moment, paleontologists named the fossil "Baby Louis." Sixteen years later, paleontologists discovered a new species named Gigantoraptor in Inner Mongolia, China. Since Gigantoraptor is a giant oviraptor that could grow as long as 26 feet (8 meters), it isn’t surprising that they laid huge eggs. In 2017, “Baby Louis” was eventually identified as an oviraptor and was named Beibeilong.

The first fossils of Yutyrannu

In 2009, the first fossils of Yutyrannus were discovered on a rock slab with the skeletons of two individuals: a large one and a small one. In 2010, another one was found – this time a baby.

All these fossils were very well preserved, and all had feathers: on the bigger adult’s tail, the smaller one’s legs and hips, and the juvenile’s neck and forelimbs.

Yutyrannus “Huali” - A Dinosaur With Beautiful Plumage

When we hear the word "feather", we would normally associate it with small- to medium-sized birds; however, that was not the case in the prehistoric era. Some dinosaurs that existed 129 million years ago in present-day Liaoning, northeastern China, were as long as 30 feet with feathers covering their ENTIRE bodies. Among these feathered giants was Yutyrannus huali, meaning the “feathered tyrant”. The specific name consists of the Mandarin “huali” (“beautiful” in English), in reference to the perceived beauty of the plumage.
