The evolution of a fossil

Kimberella reconstructions
Changing reconstructions of Kimberella, a Precambrian fossil invertebrate, which was first interpreted as a jellyfish and later as a snail-like mollusk.
More recently, another fossil creature has undergone a more dramatic reinterpretation: Nectocaris, originally interpreted as a sort of crustacean-eel chimera and, thanks to the discovery of numerous new specimens, now identified as the earliest known squid.
