The Early Euthycarcinoidic arthropod, Kalbarria (1982)
Phylum : Arthropoda Order : Euthycarcinoidea Genus : Kalbarria Species : K. brimmellae
- Silurian (440 Ma)
- 14 cm long (size)
These arthropods lived in water but also ventured onto wet sand flats, perhaps to find food. They left some of the first animal tracks on land, now preserved in fossils near Kalbarri, Western Australia. Kalbarria’s tough outer coat gave it some protection from drying out when it was out of the water.
