Inaria is an extinct genus of Ediacarian animalswith radial symmetry, which may have similarities to the cnidarians .
Initial description
The genus Inaria was first scientifically described in 1888 by Berthold Hatschek . The species name Inaria karli was designated in 1987 by James G. Gehling .
Occurrence
Inaria fossils are from the Rawnsley Quartzite ( Pound Subgroup ) in the Chace Range in South Australia and the White Sea coast of Russia .
description
The radially symmetrical organism reached a height of between 10 and 12 centimeters with a diameter of up to 12 centimeters. It had a sack-like body that resembled a bundle of garlic or an Erlenmeyer flask . Its broad, bulbous base, from which a tube protruded, was stuck in the mud. Inaria's body cavity , which served as the stomach, consisted of a single chamber, the wall of which was divided into various septa by deep grooves.
Habitat
Inaria lived in the deeper beach area and was obviously the only inhabitant of this ecozone.
