giant predators, science

Radiodontan Arthropods are some of the largest and earliest predators which were there around 500 million years ago. Scientists have been studying the fossil of Radiodontan arthropods sine many years to know more about these ancient predators. Now, a new study has suggested that young Radiodontan arthropods could be rapacious predators.

Jianni Liu conducted the study from the Northwest University of Xi’an, China. As per the stud, their babies were also amazing killers. The inspiration behind most of the science fiction monsters is the animal group called the Arthropoda. This group includes crustaceans, spiders, and insects. They all have terrifying appendages.

Most of the oldest arthropod species belonged to the Radiodonta. These species were equipped with large, spiny raptorial appendages on the front. During that time, these are considered as the giant predators, with the one-meter long body. Till now, scientists have not discovered anything about the feeding habits of the species. Liu examined the preserved juvenile of a species named as Lyrarapaxunguispinus, around 518 million-year-old from China and found some important information on arthropods.

The body length is around 18mm and represents world’s smallest radiodontan ever discovered. The Lyrarapaxunguispinus was a proficient killer since their born. The new study has suggested that raptorial feeding habits in juveniles appeared during the evolutionary history of arthropods.

The study also indicates some facts about the rapid evolution of the ancient and first animals, presented on the Earth around one billion years ago. It has theorized that predation was a major factor in the evolution. The predators are placing selective pressures on animal communities that lead to prey animals to change, evolve or lead to their extinction. The scientists are now examining the fossil to learn more about their evolution and their feeding habits.
