Such organisms are found world-wide at sites like the famous Burgess Two men and a truck Luneburg in the Canadian Rockies, where their soft bodies are preserved intact.

The strange anatomies exhibited by these animals led the American palaeontologist Stephen Jay Gould to speculate that these organisms represented extinct body plans that are no longer seen today and that if we were datea wind back the clocks to the Cambrian, more than million-years-ago, and re-run the tape of life, then perhaps the animals alive today would look very different.

More than 50 years after Doolittle Walcott came up with his theory about Amiskwiascientists investigated its affinities and rejected his interpretation as they could not find evidence of the canonical grasping spines.

Luke Parry said: "We were excited to see that these researchers found a relationship between arrow worms and rotifers. The researchers find that Amiskwia is a stem lineage to arrow worms that possess the jaw apparatus seen in gnathiferan worms.

This jaw evolved into the fearsome grasping spines in living arrow worms, which now is an important link in the marine food chain. Small crustacean larvae have evolved long protective spines to protect themselves from being swallowed by arrow date.
