Trilobite from Canada
Time: Middle Ordovician
Trenton Group, Neuville, Quebec, Canada
plate displays a rarely seen example of a trilobite found in the
Middle Ordovician Trenton Group deposits of Neuville, Ontario, Canada.
This one is different from most trilobites of the region in large
measure due to the sweeping genal, pleural, and pygidial spines.
The spines presumably in addition to a deterrent to predators probably
served to keep the trilobite near the surface of the substrate,
much as snowshoes do. This is a very fine, 3-D example of the type.
