They find the fossil of a huge Cambrian animal | Digital Trends Spanish

Palaeontologists from the Royal Ontario Museum have discovered lthe remains of a huge new species belonging to a group of extinct animals corresponding to the Cambrian period.

The 500-million-year-old fossil has been located in Kootenay National Park, in the Canadian Rockies. The species has been named as Titanokorys gainesi and according to experts. It stands out for its disproportionate size in comparison with the rest of contemporary species. Its length was 0.5 meters, so the Titanokorys was quite a giant if we consider that most of the animals that lived in the sea at that time were barely the size of a little finger.

“The size of this animal is absolutely mind-boggling, it is one of the largest Cambrian animals ever found,” says Jean-Bernard Caron of the Royal Ontario Museum. Titanokorys gainesi belongs to a group of primitive arthropods called radiodonts that inhabited the Cambrian. This period was a momentous time in the history of our planet, as almost all major forms of animal life appeared suddenly in an event known as the Cambrian explosion, something that had never happened or happened again.

Radiodonts, like this Titanokorys, had multifaceted eyes (grouping between 12 and several thousand receptive units) as well as a tooth-lined mouth, claws under their head to capture prey, and a body designed for swimming. In the case of the Titanokorys, it differs from those found so far in one key aspect: its outer shell. And it is that this is wider and flatter than the rest of radiodonts, so it seems that the animal was adapted to life at the bottom of the sea.
