Diania cactiformis- Lobopod
Early Ordovician (Arenigian)
Fezouata Formation
Mecissi-Zagora Region, Draa Valley
Morocco

A rare and scientifically important fossil of Diania cactiformis, an early Cambrian lobopodian often nicknamed the “walking cactus” due to its distinctive spiny, leg-bearing body. This organism is part of the broader stem group leading toward modern arthropods, making it a key specimen for understanding early animal evolution.
