In a 1991 paper, Ramsköld and Hou re-assigned the pre-Cambrian fossil Hallucigenia sparsa to a group of 'armoured lobopods' that had evolved defensive plates and spines. They argued that the sharp bits in the fossils were paired, upward-pointing spines.
This reversed the original reconstructions in which the spikes were interpreted as stilt-like legs.
The re-interpretation was a great relief for everyone who thought the earlier version was a bit silly and hard to animate H. sparsa's movements convincingly so that it could chase Ann Althouse across the screen.

Shirley something dreamed this name up after getting into some special fungi?
