This paleontological restoration is inaccurate, or its accuracy is disputed.
Reason: Hallucigenia sparsa with tail, distalmost 2 leg pairs with subequal length and paired claws (tail absent, distalmost 2 leg pairs shorter each with only 1 claw according to Smith & Caron 2015), and displaced anterior lobopods (should be ventral to the 1st dorsal spine pair); Tail of H. hongmeia and H. fortis exaggrerated; Lack of anterior lobopods in H. fortis (2 pairs evident).
