The crocodile family is a typical group of killers lurking in freshwater, with only a few species such as bay crocodiles occasionally entering the ocean. During the Mesozoic period when dinosaurs ruled the earth, some crocodiles were so well adapted to life in the ocean that they didn't even have the appearance of crocodiles!
<h1>Germany's "dinosaur teeth"</h1>
Germany has an important place in the history of the discovery of paleontological fossils, and fossils from Sorenhofen and Hodsmarthen have shocked the fossils time and time again. In the Solenhofengraphic limestone (Solenhofengraphic limestone), archaeopteryx, megalosaurs, beaked pterosaurs and other paleontology have been discovered.

In addition to small dinosaurs, pterosaurs and various marine life, some large and sharp tooth fossils have also been found in the limestone layers. In terms of the shape and characteristics of the teeth, it is clear that they belong to some kind of larger theropod carnivorous dinosaur, so in 1856, the paleontologist von Quenstedt named Dakosaurus (also translated as Dakosaurus, Duck crocodile), which means "biting lizard", because its full mouth of fangs was born for biting.

After Dakron was named, paleontologists found more fossils, not only in Germany, but also in Europe and even Central and South America (Mexico and Argentina).

More and more fossils have been revealed to the true face of Duck dragon, which is not actually a dinosaur, but a marine crocodile! Why is there such an error in the classification of Dakron? The problem is in Dakron's teeth. Common crocodiles, the teeth are conical, but the teeth of the Dakron are very different, and they are flattened. Dakron's teeth are not only flattened, but also have serrated structures on the edges of the sides, which is a typical carnivorous dinosaur tooth feature, and among all known crocodiles, dakron's teeth are also unique, no wonder it is wrong.

The distinctive teeth exposed the ferocious nature of the Dakron, with the crocodile-conical teeth mainly used to pierce and immobilize prey, while the Dakron's teeth were more suitable for biting and cutting. As the dakron scientific name originally meant, it is an animal that is good at "biting".
<h1>The least "crocodile-like" crocodile</h1>
The standard shape of a crocodile is a flattened head, a thick body, a slender tail behind it, short limbs, and webbing between the fingers. If you incorporate the above characteristics into the Dakron, you will find that the Dakron is not a crocodile at all.

Dakron's large head is tall, triangular on the sides, pointed at the front and wide at the back. Dakron's pair of nostrils are located in front of the head, and there are a pair of large eyes on either side of the skull. As mentioned earlier, in the large mouth of The Duckloon there are two rows of sharp teeth, and the muscles on its skull and mandible provide great bite force.
Dakron 's head was followed by a short, thick neck and cylindrical body , with a tapering tail at the back of the body , but with a tail fin at the end of the tail. Corresponding to the caudal fin, the limbs of the dakron healed, forming a paddle-like fin-like limb that functions to steer and control the balance of the body.
Are the characteristics of the Dakron described above different from those of crocodiles? The Dakron Place has such a shape, which is completely adapted to life in the ocean. While abandoning the ability to return to land, Dakron has the shape of a fish, able to swim and turn quickly in the water, and this marine crocodile with a body length of between 4 and 5 meters is the most adapted crocodile to marine life.

<h1>The killer who dominates the shallow sea</h1>
From the strata where the Dakron fossil was found, its life time is still very long, from 157 million years ago to 137 million years ago, from the Jurassic to the Cretaceous.

Dakron is home to the shallow sea, in the case of the Sauronhoven limestone formations, where fossils were first found, representing the subtropical shallow sea environment of the Late Jurassic. In addition to Archaeopteryx and Megalosaurus that lived on the island, the most commonly found in this formation is a variety of marine life, including ammonites, squid, fish, as well as ichthyosaurs and sea crocodiles. In addition to Duckloids, sea crocodiles have been found in the limestone formations of Sorenhofen as well as larger ground dragons (Plesiosuchus) and smaller narrow lizard crocodiles (Steneosaurus). The Earth Dragon and the Dakron were the top hunters in the ocean at that time, and the small narrow lizard crocodile became the prey of the Dakron.

The large and unusually fierce Duck dragon did not look at small fish and shrimp, and its main food was ichthyosaurs, such as Aegirosaurus, which was only 2 meters long. The Duck Dragon would rush up, open its mouth and bite violently, and the huge bite force could even bite the body of the ichthyosaur in two. Living in the shallow seas from the Jurassic to the Cretaceous, the most important thing to watch out for is the Dakron, if it bites, it is not far from the ghost gate.
