Here is an extremely large fossil algae specimen. This is Margaretia dorus from the Cambrian of Utah. This specimen was found by Steve Hess in 2008 at the public quarry. Margaretia was probably a thin, frond-like algae similar to modern kelp. The fronds are perforated by a network of small oval holes. This type of algae is also found in the famous Burgess Shale deposits of Canada. This specimen has wonderful form and very good detail. The algae frond is over five inches long - it is extremely rare to have a Margaretia specimen so large. The algae is well positioned on the large, natural plate of matrix that also has many trilobite parts on the back side. This is a textbook example of this enigmatic fossil from Middle Cambrian.
