Fossil conulariid

Fossil conulariid

Distinctive fossils like this conulariid have been found in 200–205 million-year-old rocks from Southland. The identity of this extinct group of animals is unknown, but many scientists consider that they represent a polyp stage of ancient staurozoan jellyfish. About 5 centimetres high, the fossil has the shape of an elongated pyramid. The alternate rows of markings on the surface are a feature of conulariids.
