Remarkable Fossil Sea Creature -- 525 Million Years Old -- Shows Soft Parts of Body Including Tentacles (http://www.sciencedaily.com/releases/2011/03/110324153024.htm)
QuoteScienceDaily (Mar. 28, 2011) â€" Researchers from China, Leicester and Oxford have discovered a remarkable fossil which sheds new light on an important group of primitive sea creatures.
The 525-million-year-old fossil belongs to a group of tentacle-bearing creatures which lived inside hard tubes. Previously only the tubes have been seen in detail but this new specimen clearly shows the soft parts of the body including tentacles for feeding.
The detail in the fossil record continues to increase and our understanding of the very early soft bodied multi-cellular organisms grows along with it.
