Large Inflated Salterocoryphe Trilobite from Portugal |
||
|
|
||
Name:
Salterocoryphe
saltori Phylum: Phacopida Family: Calymenidae Age: Ordovician Size: The trilobite is 1 7/8” in length on a 3 x 6” plate. Fossil Location: Valongo Formation, Covelo, Portugal Comments: This specimen exhibits all the hallmark attributes of the best-preserved Valongo trilobites. One is struck immediately by the exquisite preservation, color and aesthetics of this specimen. It is fully prone and inflated, resting comfortably on the matrix. Valongo trilobites are easily recognized by their ghostly appearance. They are normally compressed, distorted, and the matrix has a slatey appearance. This formation is a monotonous succession of marine silty mudrocks transformed into dark slate by low regional metamorphism.

Premium Ellipsocephalus hoffi Trilobites Mass Mortality Plate |
||
|
|
||
Name:
Ellipsocephalus
hoffi
Age: Middle Cambrian Size: The trilobites average ½ to 1” in length on a 3 ½ x 5” plate. Fossil Location: Jince Formation, lower part ot the Hydrocephalus lyelli Zone, Czech Republic Comments: Description: This abundant species could form monotypic cluster of tens to hundreds of specimens. This plate has 11 complete and many partials. The specimens well defined 3D and contrast well against a dark background. It’s a very pretty plate and shows quite well. There are more that 1300 described species of Barrandian trilobites. An amazing statistic when you consider the area collected is only a few hundred square miles. Bohemia is the historical name given to the area of central Czech Republic where these species are found. Barrandian trilobites refer to the trilobite fauna found here. The term comes from the seminal work done by the J. Barrnade (1799-1883) who spent over half his life describing these trilobites and helping establish the science of paleontology.

Lonchodomas drummuckensis Trilobite from the Girvan Starfish Beds of Scotland |
||
|
|
||
Name:
Lonchodomas
drummuckensis
Age: Upper Ordovician Size: The trilobite is 1 5/8” in length. Fossil Location: Ashgill Series, Rawtheyan Stage, Drummuck Group, Aryshire, Scotland Comments: Presented is rare treat from an old collection that I managed to acquire. Lonchodomas drummuckensis are from the classic “Starfish” Beds of Girvan. This location is now protected and off-limits to any kind of fossil collecting. This is an excellent quality specimen, only the right genal spine is missing. (It is highly unusual to find complete specimens from this site.) It has a dark chocolate color, is inflated and shows very well. The species is readily identified by the long nose spine and flaring genals.

Classic Bohemian Trilobite Otarion diffractum |
||
|
|
||
Name:
Otarion
diffractum
Age: Silurian Size: 9-mm on a 4 x 4-cm plate Fossil Location: Kopaninske Fm., Kosov, near Beroun, Czech Republic) Czech Republic Comments: This species is somewhat rare and I have only received a few of them. This is my last one to offer. It apparently is from the Aulacopleuridae family, and closely resembles Aulacopleura koninckii and comes from the same formation. Note the excellent preservation including the eyes and long genal spines. To the upper left is a partial of what appears to be an Odontopleura.

Large Bizarre Crotalocephalus Moroccan Trilobite |
||
|
|
||
Name:
Crotalocephalus
gibbus
Age: Devonian Size: The specimen is 7.9 cm (3 1/8”) on a 13.3 x 8.8 cm (5 ¼ x 3 ½”) piece of flat-lying matrix. Fossil Location: Hamar Laghdad Formation, Djebel Issoumour, Alnif , Morocco Comments: Presented is an excellent example of this unusual and bizarre looking trilobite genus. Take special note of the highly inflated, pronounced glabella, set in extreme opposition to the small eyes. Well preserved example of a member of the Order Phacopida, Family Cheiruridae with many fine details present. The most diagnostic features of this taxon are the sharp pleural and pygidial spines and the distinctive cephalon. The describer of this one thought it bore a resemblance to the head of a rattlesnake (Crotalus), hence the genus name. The spines may have aided it in staying at the surface of the soft seafloor.

Surprise Moroccan Oryctocephalidae Trilobite |
||
|
|
||
Name:
Shergoldiella
vincenti (Geyer 2006)
Age: Lower-Middle Cambrian Size: The trilobite is 7/16” in length on a small plate. Fossil Location: Lower Jbel Wawrmast Formation Tarhoucht area, eastern Anti-Atlas, Morocco Comments: If you have ever attended the Tucson Gem and Fossil Show, you know how difficult it can be to navigate the many Moroccan fossil dealers. There are so many fakes and commercial junk to wade though to find the real relevant fossil treasures. Here is one that was lying in a cardboard box under a table in the tent of a quite innocuous Moroccan dealer; far away from the main hotel showrooms. This Shergoldiella vincenti is the only known genus of Oryctocephalidae found in Morocco. Only a few have been discovered. Surely, this would be a treat for the Moroccan trilobite specialist. It is quite well preserved, fully prone with a bright rust/orange patina. It’s the only one I have to offer. Price: $170.00 - Code PFT729 - Purchase |

Large Robust Bolivian Hoekaspis yahuari Trilobite |
||
|
|
||
Name:
Hoekaspis
yahuari (Hoek 1912)
Age: Middle Ordovician Size: The trilobite is 4” in length. Fossil Location: Bolivia Comments: Description: Another fossil that was readily available about seven years ago has now become rather uncommon. I would assume the quarry site was exhausted. Most Bolivian fossils are found in concretions. This one was as well, though, the negative is lost. Importantly, it retains its free cheeks. Note the light rust/orange patina covering most of the trilobite. Most of the Hoekaspis recovered were molts with their free cheeks missing. This is a high-grade specimen, and is one of only two I have available. Price: $225.00 - Code PFT777 - Purchase |

Ectillaenus
giganteus
Order: Corynexochida Family:Illaenidae Placoparia tournemini Order: Phacopida Family: Pliomeridae Age: Ordovician Location: Valongo Formation, Covelo, Portugal Size: (25.4mm=1 inch): The Ectillaenus is 3 1/2” in length, the Placoparia ¾”. The plate size is 8 5/8 x 5 1/2” Comments: Valongo trilobites are easily recognized by their ghostly appearance. They are normally compressed, distorted, and the matrix has a slatey appearance. This one is part of a small batch of exceptionally well-preserved specimens that I recently procured. One is struck immediately by the exquisite preservation, color and aesthetics of this large two species association plate. Both the Ectillaenus and Placoparia are fully prone and inflated, resting comfortably on the matrix. Special attention needs to be paid to the fact that both specimens show none of the distortion, crushing and stretching normally associated with Valongo trilobites.
