Oesia disjuncta Walcott, 1911 known as "Margaretia dorus Walcott, 1934"
oilshale posted a fossil in Other Invertebrates
Originally interpreted as a green algae with a relationship to the modern green alga Caulerpa, Margaretia dorus is now considered to be the feeding tube of the hemichordate Oesia. The position of Oesia is uncertain. Originally described as an annelid worm by Walcott (1911), a recent reinterpretation as a chaetognath (Szaniawski, 2005, 2009) has been vigorously rejected, and a position closer to the hemichordates proposed instead (Conway Morris, 2009). Margaretia dorus would now be a junior synonym of Oesia disjuncta Walcott, 1911 References: Simon Conway Morris and R. A.

"In the past, hyoliths have been interpreted as being related to molluscs, which are common today and include squid, clams and snails. The new research suggests the animals are in fact more closely related to a different group of shell-bearing organisms, known as lophophorata, which includes brachipods (lamp shells), among others." http://www.bbc.com/news/science-environment-38585325

QUOTE "As the oldest direct evidence of a creature caring for its offspring, the discovery adds another piece to our understanding of brood care practices during the Cambrian Explosion, a period of rapid evolutionary development when most major animal groups appear in the fossil record," said Jean-Bernard Caron, curator of invertebrate palaeontology at the Royal Ontario Museum and associate professor in the Departments of Earth Sciences and Ecology & Evolutionary Biology at the University of Toronto."

This is my Sanctacaris replica I make.

This is another of my Burgess shale replicas

This is my most recent sculpture I have made. I sculpt the original in clay. It usualy takes me a few months to complete a sculpture. When I am happy with the piece, I make a silcone mold of it. With the mold, I am able to cast a model in Urethane plastic. Once it is cast I can clean up the piece and I can airbrush it.
