Arctinurus boltoni
Vendor: Fossil Soup
SKU Number: SQ0282063
A stunning example of a classic Middle Silurian trilobite from the famous Rochester Shale “Caleb Quarry” location near Middleport, NY.
Arctinurus boltoni is a large lichid trilobite that is known from reasonably deep water and tropical regions. All of these trilobites show indications of either minor restoration or repair due to the water saturation of the rock and the paper thin fossilization of the carapace. That said, we were hard pushed to categorically identify any restoration or repair that usually occurs on the pleural and pygidial spines.
There is indication of some work taking place on the shale to stabilize the rock, this is also expected and a normal part of the preparation process for these trilobites. This specimen is very typical of the species from Caleb Quarry at around 4 inches in size. It exhibits surface granules or tubercles and is perfectly articulated. A great American trilobite that graces the collections of museums across the world and is becoming increasingly harder to find on the open market.

Additional Information
Arctinurus was first reported in upstate New York during the construction of the Erie Canal as rock was removed from the soft Silurian shales and mudstones. Before the late 1990s, complete Arctinurus fossils were very rare. Lichids are typically spiny, their exoskeletons often have a grainy texture or have wart or spine-like tubercles.

Olenoides vali Middle Cambrian, Wheeler Shale, Millard County, Utah.
This is an extremely rare and spiny trilobite that is very rarely available on the market. The spines are large and free standing with the occipital spine curving back towards the axial lobe.
This is a very high-end trilobite for the very discerning collector. Very likely the only one currently being offered on the open market!!!
Due to some damage, this trilobite is being offered at a very reasonable price. You won’t find another one available anywhere, or at a price anywhere close to this! Sure to go quickly!

Coosella rieri from the Middle Cambrian, Weeks Formation, House Range, Millard County, Utah.
Like many of the trilobites from the Weeks Formation, this is a rarely seen trilobite. This example is quite large at over 2 cm. Coosella trilobites are characterized by opisthoparian facial sutures, which is the most common suture type in trilobites. The suture runs from the front of the cephalon to the posterior margin.
Fossil size:
Length: 2.4 cm
Width: 1.5 cm
Height: 0.1 cm
Matrix size:
Length: 24.0 cm
Width: 15.0 cm
Height: 1.0 cm

Rhombampyx yii trilobite from the Middle Ordovician, Meitan Formation, Zunyi, Guizhou, China.
The distinct oval/rhomboid dome where the anterior needle spine meets the head is the highly inflated glabella. It is slightly compressed but shows the distinctive bulbous shape unique to raphiophorids.
You can clearly see a thin, straight line pointing straight up from the top of the glabella. This is the base of the median snout spine.
The two elongated cheek spines can be seen on either side of the body. In life, these spines flared outward to stabilize the animal or deter predators, but post-mortem movement or burial compaction has curved it around the cephalon.
