 Description:
This fine plaque houses six Onnia superba trilobites in a NATURAL
assemblage (NOT a composite). There are many fine details evident
such as the pitted cephalic ring by which the trilobites fed. They
presumably swam along just above the seafloor, using their legs to
kick up suspended matter into their filter chamber with the water
existing dorsally through the fenestrae (pits, Latin for windows).
Whatever catastrophe overtook them, it provides an opportunity for
a collector to add these for only about $50/example. |
