Bolaspidella housensis - Chancelloria sp.
Vendor: Gold Bugs
SKU Number: SQ0220508
A rare combination plate featuring the spiny trilobite species Bolaspidella housensis and the rare and bizarre sponge Chancelloria pentacta.
Bolaspidella is a small species of trilobite, featuring a rack of standing spines on its axial rings. The front of the plate features 2 complete examples, with a very small juvenile example to the bottom of the plate. The Chancelloria appears as a tangled mass of thorns-with its representative spicules interwoven across its surface.
The color of the sponge is striking. On the reverse side of the plate is another larger example of Bolaspidella housensis, along with bits and pieces of trilobites. This is a stunning plate.

Additional Information
The Wheeler Shale formation was named by Charles Doolittle Walcott. The Wheeler is a Konzentrat-Lagerstätte of soft tissued organisms preserved as carbonaceous film on calcareous shale, shaley limestone, mudstone and thin flaggy limestone.
Bollaspidella is a member of the order: Ptychopariida, a large heterogeneous order of trilobite containing some of the most primitive species known. The earliest species occurred in the second half of the Lower Cambrian, and the last species did not survive the Ordovician–Silurian extinction event.
