Description

Phyllocarid
Dithyrocaris sp.
Late Devonian
Yukon Territory United States

Enormous 24 inch (610mm) complete phyllocarid arthropod.
Absolutely spectacular. Easily one of the best fossils and
certainly one of the biggest arthropods we have ever had. Email for shipping information, it is very heavy and will require special handling.

Dithyrocaris is a genus of phyllocarid, a subclass of crustaceans (Phyllocarida) known primarily from isolated carapaces. The fossils of this genus are found in the Devonian to Carboniferous of North America, Bolivia, and Scotland. Phyllocarids, as a group, date back to the Early Cambrian with one order still living today.

This one was completely unexpected. The average phyllocarid might be 2-3 inches long (5-8cm) but this one is TWO FEET LONG. The one scientific paper written about it cites it as the largest phyllocarid ever found. It’s way past gigantic. It’s ginormous! It’s phyllogantic!
