Leonaspis

LEONASPIS Leonaspis has a wide head, drawn out to the side and rear into exceptionally stout genal spines, and with small, slightly elevated eyes. The ten thoracic segments have wide pleurae, extending into robust spines, and straight pleural furrows. The tail shield is also very spiny. Habitat: A bottom-dweller, this genus used its spines for protection. Remark: This type of trilobite had a long stratigraphic range. Â© 1992 Cyril Walker, David Ward .
