Morphology

Orstenotubulus was a Mid Cambrian lobopodian. It had an elongated, thin body with pairs of dorsal spines running down the entire top of the body. It also had tiny retractable spines ventral to the leg surface. Orstenotubulus would have crawled along the sea floor like most other lobopodians, using its dorsal spines to deter any predators.
