Unveil the secrets of giants past! Our guide explores the 8 most incredible real dinosaur bones on display at the Zigong Dinosaur Museum. Immerse yourself in the Jurassic era and come face-to-face with these awe-inspiring fossils. Real dinosaur bones await!

What are the real dinosaur bones?

What is the composition of dinosaur bones?

Dinosaur bones are fascinating examples of natural engineering. Primarily composed of hydroxyapatite, a mineral rich in calcium and phosphate, they also contain collagen, organic molecules, and trace elements. This unique combination provided the strength and structure needed for these fossil bones to support the massive bodies of dinosaurs.

How can experts tell if a relic dinosaur fossil is real?

Experts have a more sophisticated toolkit. They compared bone structure to dinosaur anatomy, checked surrounding rocks for geological consistency, and even analyzed the chemical makeup and age of the bones. Microscopic views revealed the internal structure of the bones, and comparisons were made with known dinosaur specimens. By combining these methods, experts can determine whether a fossil is a genuine window into the past or a clever recreation.

Where Were The Dinosaur Fossils Found In Zigong Dinosaur Museum?

The Zigong Dinosaur Museum in Zigong City, Sichuan Province, China, houses a world-renowned collection of dinosaur fossils. These fossils were unearthed in the Sichuan Basin, specifically in two nearby geological formations: the Shaximiao Formation and the Dashanpu Formation.

The Shaximiao Formation, located about 7 km northeast of downtown Zigong, was once a vast lake during the Jurassic period. This tropical and humid environment was ideal for dinosaurs, and their remains are exceptionally well-preserved after being buried in mud and sand on an ancient sandbank. The museum itself is built on top of a rich concentration of fossils from this formation.

The Dashanpu Formation is another treasure trove of dinosaur fossils in the Sichuan Basin. The formation is known for its abundance and diversity of dinosaur remains, including sauropods, theropods, and other prehistoric organisms.

Is there a real dinosaur fossil? Of course, the answer is YES! Zigong Dinosaur Museum’s collection of fossil specimens includes nearly all known dinosaur species from the Jurassic period between 201 and 145 million years ago, making it the largest collection and display of Jurassic dinosaur fossils in the world. Let’s talk about the 8 best real dinosaur bones in Zigong Dinosaur Museum.

1. Sauropod

Shunosaurus lii

Shunosaurus was a medium-sized sauropod, measuring about 12 meters (40 feet) long and weighing about 8 tons.

Shunosaurus lii’s skull was moderately tall and long, and its teeth were elongated and spoon-shaped. The tail had a bony tail hammer at the end that functioned like the membranous tail hammer of ankylosaurids. This type of short-necked sauropod dinosaur is the main member of the Zigong Dashanpu dinosaur fauna. To date, more than 30 relatively complete individual materials of all sizes have been discovered.

Tianfuosaurus

Tianfuosaurus was a large sauropod, measuring about 23 meters (75 feet) long and weighing about 30 tons. “Tianfuosaurus” means “Heavenly Capital lizard”, referring to the city of Chengdu, which is the capital of Sichuan Province.

Tianfuosaurus had a relatively large skull with spoon-shaped teeth and a neck consisting of 17 vertebrae. The longest cervical vertebra is approximately 3.5 times longer than the longest dorsal vertebra. It has thick-boned limbs and lives mainly on broad alluvial plains, feeding on the crowns of tall trees. The well-preserved skeleton is 20 meters long.

Young’s Mamenchisaurus

Young’s Mamenchisaurus is estimated to have grown up to 22 meters (72 feet) in length and weighed around 25 tons. It was known for its incredible neck length, which could reach up to 11 meters (36 feet) – longer than the entire body of many other dinosaurs!

The Young’s Mamenchisaurus dinosaur teeth were spoon-shaped, and its long neck was composed of 19 vertebrae. The longest cervical vertebra was about 3.5 times the longest dorsal vertebra. It has thick bones in its limbs and mainly lives in vast alluvial plains, feeding on the crowns of tall trees.

2. Theropod

Jiansheqilong

Jiansheqilong was a small theropod, measuring about 1.4 meters (4.6 feet) long and weighing about 25 kilograms (55 pounds).

​Its skull was large but structurally light, and its teeth were sharp, dagger-like, with serrated edges, perfect for picking muscles. Its neck and trunk are short, while its tail is long. The forelimbs are reduced and suitable only for grasping food. The hind limbs are robust, with sharp claws on the toes. It was a ferocious bipedal predator.

Szechuanosaurus

The Szechuanosaurus is estimated to be a medium-sized theropod, reaching lengths of around 7.3 meters (24 feet)

​Szechuanosaurus had large bones but a light structure, and sharp, dagger-shaped teeth with serrated edges that were well-suited to picking muscles. The neck and trunk are short, while the tail is long. The forelimbs are reduced and suitable only for grasping food. The hind limbs are robust, with sharp claws on the toes. It was a ferocious bipedal predator.

Hepingchuanosaurus

The Hepingchuanosaurus is estimated to be a large theropod, reaching lengths of about 9 meters (30 feet)

The bones of Hepingchuanosaurus were more than a meter long, and the teeth were relatively small and dagger-shaped. The forelimbs are degenerate, and the strong hindlimbs have sharp, stout claws at the end of the toes, which are used to catch prey or to cut the skin. The intact skeleton, about nine meters long, is the most complete carnivorous dinosaur known from Asia.

2. Theropod

Sichuan Gigantspinosaurus

Sichuan Gigantspinosaurus was a herbivorous stegosaur that lived in the Late Jurassic period, estimated to be around 4.2 meters (14 feet) long.

It was a medium-sized stegosaur. The skull is relatively small, has few teeth, is spoon-shaped, has a short neck, and has 15 pairs of symmetrically arranged small dorsal plates on the back of the body, which are variable in shape and often triangular. This species usually lives in the jungle near the banks of rivers and lakes, feeding on the leaves of young shrubs.

It was a large, stegosaur-type dinosaur. The skull was relatively small, with few teeth and a spoon-shaped shape, and the neck was short. The 15 pairs of symmetrically arranged dorsal plates on the back of the body are broader than those of Huayanglong but do not vary much in shape and are mostly triangular. This species usually lives in the jungle near the banks of rivers and lakes, feeding on the leaves of young shrubs. The relatively intact skeleton is seven meters long.
