Paleontologists in Canada have discovered a new species of sea animal that was 1 1/2 feet long and football-shaped, with a large protective shell over its head, a toothed mouth and a pair of spiny claws.
(It's extinct, so you don't have to worry about one of these brushing up against your leg at the beach. Read on.)
The new species — dubbed the Titanokorys gainesi — is believed to be part of a long-gone animal group from the Cambrian period some 500 million years ago.
According to scientists with the Royal Ontario Museum, who discovered the species in a fossil in Kootenay National Park, located in the Canadian Rockies, the Titanokorys would have been a giant during a time when most sea creatures grew to the size of a pinky finger or smaller.
"The sheer size of this animal is absolutely mind-boggling, this is one of the biggest animals from the Cambrian period ever found," said Jean-Bernard Caron, the museum's Richard M. Ivey Curator of Invertebrate Palaeontology, in a statement.
The Titanokorys belongs to a subgroup of primitive arthropods called hurdiids, which have long heads and a three-part carapace, a kind of hard outer shell.
"The head is so long relative to the body that these animals are really little more than swimming heads," said Joe Moysiuk, a University of Toronto Ph.D. student who co-authored the study of the new species released this week.
The scientists said the broad, flat head of the Titanokorys suggests it swam near the seafloor, using its front limbs to scoop prey toward its mouth.
A similar species, discovered in the same area in 2018, is named the Cambroraster falcatus, because scientists thought its head carapace resembled the Millennium Falcon, a ship from the movie Star Wars.
