Here is a very unusual fossil algae specimen. This is Margaretia dorus from the Cambrian of Utah. This specimen was found by Steve Hess in 2005 at the U-Dig 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 is well positioned on the semi-squared plate of matrix. This is a very detailed example of this enigmatic fossil from Middle Cambrian.
