What is the animal Vetulicolia known for?

Vetulicolia is a group of extinct marine animals that lived in the Cambrian period, about 500 million years ago.

They are known for their unusual body plan, which consisted of two parts: a large anterior section with a mouth and five pairs of gill-like openings, and a segmented posterior section that functioned as a tail.

Vetulicolia had no eyes, limbs, or other appendages, and their feeding habits and mode of locomotion are unclear.

They are also known for their controversial taxonomic position, as different studies have suggested that they may be related to arthropods, chordates, or other deuterostomes.

Vetulicolia is one of the many examples of the remarkable diversity and experimentation of life forms during the Cambrian explosion.

Where does the Vetulicolia live?

Vetulicolia is a group of extinct marine animals that lived in the Cambrian period, about 518 to 507 million years ago.
They are known from fossils found in China, Australia, Canada, and the United States.

Vetulicolia had a unique body plan that consisted of two parts: a large anterior forebody with a mouth and five pairs of gill-like openings on each side, and a segmented posterior tail that was used for swimming.
They had no eyes, limbs, or other appendages.
They probably fed on organic particles suspended in the water, using their mouth to create a suction current.

The evolutionary relationships of Vetulicolia are unclear.
They have been variously considered as stem-group arthropods, stem-group vertebrates, or early deuterostomes.
Some recent studies suggest that they are closely related to chordates, the group that includes vertebrates and tunicates, and that they may represent the sister group of tunicates.
However, this interpretation is not universally accepted, and more evidence is needed to resolve the phylogenetic position of Vetulicolia.

What does the Vetulicolia look like?

The Vetulicolia were a group of extinct marine animals that lived in the Cambrian period.

They had a body divided into two parts: a large anterior part with a mouth and five pairs of gill-like openings on each side, and a segmented posterior part that functioned as a tail.

They had no eyes, limbs, or other appendages.

They were probably filter feeders or scavengers.

Some scientists think they were related to the deuterostomes, a group that includes chordates and echinoderms.
