Hallucigenia lived around 508 million years ago, and it was first unearthed in a famous Canadian fossil field called the Burgess Shale. When Conway-Morris set his eyes upon it, he saw a long tubular body, between 1 and 5 centimetres long.

How old is Hallucigenia?
The tiny sea creature - Hallucigenia - lived 500 million years ago, but all fossils appeared to be without heads. New specimens unearthed in Canada have revealed the missing part, revealing its strange face for the first time.
What era did the Hallucigenia live in?
The tiny sea creature, known as Hallucigenia due to its strange appearance, lived 500 million years ago during the Cambrian explosion, a period when most major animal groups first appear in fossil records.
Is Hallucigenia extinct?
A bizarre extinct creature that has mystified scientists since its 500m-year fossil was first unearthed more than a century ago has finally revealed its teeth – placing it centre stage in the evolution of many complex life-forms living today.
When did Hallucigenia go extinct?
It ended with the Cambrian-Ordovician extinction event, approximately 488 million years ago. The similarity of Hallucigenia to other contemporary 'legged worms', collectively known as lobopodians, has been very controversial.
Was Hallucigenia real?
Hallucigenia is a genus of Cambrian animal known from articulated fossils in Burgess Shale-type deposits in Canada and China, and from isolated spines around the world. ... Hallucigenia is later recognized as part of lobopodians, a grade of paleozoic panarthropods where the velvet worms, water bears and arthropods arose.
Are Hallucigenia still alive?
Weird fossil worm Hallucigenia descendant found and it's ALIVE. Hallucigenia, a bizarre worm that lived around 500 million years ago, was one of the strangest creatures to ever live. ... Despite their name, they are not true worms, as they achieve mobility through the use of a set of short legs.
How did the Hallucigenia live?
Hallucigenia lived deep underwater, where light is scarce. It was probably about to make out organisms swimming overheard, and their shadows.
What did the Hallucigenia eat?
Hallucigenia's lobopodian limbs would have been relatively weak and they terminated in small claws so it is thought that Hallucigenia may have lived by clinging to - and possibly eating - sponges, moving only slowly across the surface of the host whilst protecting itself from predation with its long dorsal spines.
What did Hallucigenia evolve into?
And despite its odd appearance, Hallucigenia isn't an incomprehensible zoological experiment. Paleontologists have been able to place it comfortably on the evolutionary branch that led to a group of invertebrates alive today called velvet worms.
What is the Hallucigenia in AOT?
Hallucigenia, an ancient species of aquatic lobopodian worm from the Cambrian period. This resemblance is made more apparent by the appearance of a Hallucigenia sparsa during Zeke Yeager's discussion of the origin of life.
Can Hallucigenia move backwards?
What is more, early interpretations of Hallucigenia, which was first identified in the 1970s, placed it both backwards and upside-down. The spines along the creature's back were originally thought to be legs, its legs were thought to be tentacles along its back, and its head was mistaken for its tail.
How does Opabinia eat?
Opabinia, another small Cambrian critter, grew to eight centimeters (about three inches). This creature likely caught prey with the grasping claws of its long, tube-like proboscis and then stuffed the food into its mouth — much as an elephant uses its trunk.
How big is a Anomalocaris?
For the time in which it lived, Anomalocaris was gigantic, up to 38 centimetres (1.25 feet) long excluding the tail fan and frontal appendages. Previous estimation up to 1 metre (3.3 feet) is unlikely based on the ratio of body parts (body length measured only about 2 and 2.8 times the length of frontal appendage in A.
Where do velvet worms live?
Velvet worms, otherwise known as Onychophora, are reclusive little animals that have changed very little in the last 500 million years. Scientists have described some 180 modern species. They can be found in moist, dark places all around the tropics and Australia and New Zealand.
What caused the end of the Cambrian period?
Just as the first complex animals were settling into Earth's oceans, oxygen levels fell dramatically and wiped many of them out. The finding shows that the birth of complex life was beset with dangers.
