As the name implies, "mysterious creatures" are unconfirmed creatures, but there are dozens or hundreds of unconfirmed creatures in this world. Of course, with the exploration of scientists, the veil of many mysterious creatures is slowly being unveiled.
For example, "Flying Cat" was a mysterious creature before the 20th century. It has wings like a bat and looks like a cat, but in fact, "flying cat" is probably a flying mouse.
Most of these so-called "mysterious creatures" have multiple witnesses, and the descriptions of different witnesses are quite different, which casts a thick veil on these unknown creatures, and most of these mysterious creatures appear in the era of underdeveloped technology. Therefore, these mysterious creatures are either creatures that we have not yet explored, or the result of the spread of truth from one source to another.
Extinct ancient animals:
Trilobites are one of the extinct ancient animals. Its back is a solid skeleton called crustacean, and its abdomen is mainly composed of a soft peritoneum and two rows of slender legs. The carapace is divided into head, chest and tail from front to back, and the chest includes several chest segments. Because crustaceans are divided into three parts, obviously, like three leaves side by side, they become trilobites.
