Here is a very fine example of an unusual fossil. This is a double Dictyonema retiforme, a graptolite, from the Silurian of New York. Dictyonema was a fan-like colony that attached to the bottom of the sea with a fibrous holdfast. This wonderful specimen has two very nice examples of the fan-like colony preserved on the large plate. The distinct fossils have excellent color and contrast and very fine detail preserved. This is a very uncommon pair of enigmatic fossil graptolites from New York.
A Certificate of Authenticity from EXTINCTIONS is included with this specimen.
