Hallucigenia is a genus of lobopodian known from Cambrian aged fossils in Burgess Shale-type deposits in Canada and China, and from isolated spines around the world. [4] The generic name reflects the type species' unusual appearance and eccentric history of study; when it was erected as a genus, H. sparsa was reconstructed as an enigmatic animal upside down and back to front.

Sauropod necks have been found at over 15 metres (49 ft) in length, a full six times longer than the world record giraffe neck. [45] Enabling this were a number of essential physiological features.

Like all sauropods, Nigersaurus was a quadruped with a small head, thick hind legs, and a prominent tail.
