In outcrop, the radiating pattern of this trace is not as obvious as when seen along bedding planes. Species. Asterosoma is a trace fossil, rather than a specific animal or plant fossil. It is given a genera name as a distinctive pattern or trace.

Geoconservation emphasises the conservation of geodiversity for its inherent geoheritage and ecological value.
