Cuenca Dragon Hunt: Cretaceous Hunchback Killer Cuenca Dragon Hunter: Cretaceous Hunchback Killer Mention the hunchback animals, everyone must think of camels, in fact, some dinosaurs also have a hunchback-like structure on their backs, including a carnivorous dinosaur that lived in Spain during the Cretaceous period, this dinosaur is the strange-looking Cuenca dragon.

When it comes to animals with hunchbacks, everyone will definitely think of camels, in fact, dinosaurs will also rise hunchback structures!

In the central part of Spain is the province of Cuenca, where the climate is dry and the land is barren, and geological features such as cone mountains and canyons are common. Beneath the earth's exposed rocks, fossils of paleontology can often be found. In 2002, paleontologists in Spain found a relatively complete dinosaur fossil in these rock formations, and when people cleared the rocks covering the fossils, a dinosaur fossil that maintained a skeletal connection was presented in front of people. Judging from its degree of preservation and the state of the bone link, this dinosaur stayed in place after death and belonged to the burial in situ.

Dinosaur fossils unmistakably show that they belong to carnivorous dinosaurs. Since the fossil was found in the province of Cuenca, it was named concavenator.

The most prominent feature of the Cuenca Dragon is the structure of the nerve spines protruding from its back. In the recovery of the Cuenca Dragon, its back protrudes, like a hunchback protrusion. The hunchback structure has undoubtedly become a recognizable symbol of the Cuenca dragon hunter, but paleontologists cannot determine the role of this structure. Some argue that the hunchback structure of the Cuenca dragon was suitable for regulating the temperature of the body, while others believe that the hunchback was a visual identifier.

The hunchbacked Cuenca Dinosaur was a medium-sized carnivorous dinosaur with a body length of about 6 meters, a hip height of 1.8 meters, and a weight of about 800 kilograms. As a carnivorous dinosaur, the Cuenca Dragon had a large head and a pair of large round eyes on either side of its head, so it had good eyesight. In the mouth of the Cuenca dragon hunter, there are two rows of sharp curved teeth, which are their prey weapons.

The Cuenca Dragon was strong, with a long tail behind it to maintain balance in its body as it walked and ran. The Cuenca Dragon has long forelimbs, three fingers on its hands, and sharp claws at the ends of its fingers. Compared with the forelimbs, the hind limbs of the Cuenca Dragon are longer and stronger, which means that it has a fairly strong athletic ability, and the Kunca Dragon runs really fast.

While studying fossilized bones of Cuenca dragon hunters, paleontologists found a feather nodule structure on the ulna of its forearm, a row of small bony protrusions that are very common on the ulna of today's birds and function as attaching long feathers. It is precisely because of the feather structure left on the ulna that paleontologists believe that the forelimbs of the Cuenca dragon have feathers, but the role of its feathers is also a mystery.

Spanish killer of the Cretaceous

The Cuenca Dragon lived during the Early Cretaceous period, 130 million years ago, in Spain. Based on the formations in which the fossils were found, scientists determined that the Cretaceous Spanish climate was much warmer and wetter than it is today, when large inland lakes existed and stretches of green forests grew around them.

In freshwater lakes and forests, a variety of animals live, including many dinosaurs. Paleontologists have found dromiceiomimus belonging to the ornithistorans and mantellisaurus belonging to the iguanodonate. Both dinosaurs were prey to the Cuenca dragon hunters, but when it came to hunting them, the Cuenca dragon hunting strategy was completely different. For emu-like dragons, the Cuenca Dragon Hunter needs to be hunted quickly; for the Mantel Dragon, the Cuenca Dragon Hunter must be a hard-hitting contest of strength.

There is no doubt that the Cuenca Dragon Hunter was the top killer of Early Cretaceous Spain, a hunchbacked carnivorous dinosaur that was the ruler of Spain at the time. ps: The Cuenca Dragon Hunter once appeared in the movie "Jurassic World 2", if you look closely, you will find that there is a strange guy with a hunchback structure in the dinosaur restoration scene under the castle, that is a Kunka Dragon Hunter!
