Vietucnews – An intact fossil of a completely new species in the class trilobite (trilobite) has just been found in a rock at Emu Bay, on Kangaroo Island (Australia), which is world-famous as a “mine site” “full of prehistoric creatures.

The interesting features of the strange creature just discovered in Australia led researchers to name it Redlichia rex, with the word “rex” taken from T-rex – tyrannosaur.

The most surprising thing is the terrifying size of this “bug”: up to 30 cm long. It was twice the size of the largest trilobite ever discovered, and too massive for all the bugs that exist in the world today.

This “tyrant” beetle lives on the bottom of the sea, has terrifying legs and spines to crush and shred food. Its diet can be very diverse, including smaller trilobite congeners.

This specimen is also valuable in that the “stone tomb” preserved the animal’s soft parts, including antennae and legs, which are extremely rare in the world of paleontology. This monster and its kind – other trilobites – appeared on earth at the beginning of the Cambrian period (about 540 million years ago) and became extinct about 252 million years ago, or the end of the Permian period.

The work, led by Diego García-Bellido, a researcher at the University of Adelaide and the Museum of South Australia, has just been published in the Journal of Systematic Palaeontology.
